The post Hirox Power Hiscope KH-2700R appeared first on BMI Surplus.

This is a 'not-quite-complete' Bausch & Lomb Dynazoom metallurgical microscope that has been modified for the observation of extra opaque samples. This was accomplished by the addition of a spacer block which raises the limb about an inch higher from the base. The stage carrier has been modified so the stage sits a similar distance further from the viewing head, thus providing extra room for the vertical illuminator assembly.

These microscopes are very modular, so it is helpful to state how this one is configured. The stand itself features a low-set coaxial coarse and fine adjustment mechanism that is comfortable to use with the hands resting on the table surface. The stage is the plain type without any mechanical stage attachments. It is provided with a fixed condenser sleeve underneath the stage into which a simple single-lens condenser and iris have been clamped. The condenser does not appear to be factory original.

The base of the stand includes an optional hi-intensity illumination housing with a lamp socket. This housing has a centerable field iris diaphragm with built-in filter recess. There is no transformer for the transmitted light illumination, it will need to be sourced elsewhere. The plug on the end of the transmitted light socket is missing.

The stand is provided with the most elaborate version of the many tubes that were available for this instrument. This microscope tube has binocular observation and a control knob to switch the light path into a port on the top of the tube. It also features a 1x to 2x continuous zoom mechanism that operates in both the photo and binocular ports. The zoom knob is graduated. The microscope pod may be turned through 180 degrees so the limb of the stand may either be away from or close to the observer (the vertical illuminator prevents continuous rotation). A pair of B&L 10x wide field oculars is supplied as is a photo-port adapter collar. This collar would be used with various shutter housings that Bausch & Lomb manufactured for their camera systems. No cameras are included.

The vertical illuminator is the most elaborate of the several Bausch & Lomb provided for the Dynazoom. Called the 'Trivert', it has provisions for bright field, dark field, and (when so optioned) polarized light. Please note that no polarized light accessories are included with the equipment! The illuminator has separate field and aperture diaphragms and a slot for receiving filters. A selector knob next to the beam-splitter swings in a central stop for observations in dark field (field and aperture diaphragms must be fully opened). This illuminator is missing the socket for the lamp (it was tested with the socket from another instrument). Also missing is the Jeffey transformer for regulating the missing GE 1630 low voltage lamp.

The base of the illuminator carries a quadruple nosepiece positioned away from the observer allowing better viewing of the specimen. The objectives are all of a special version with annular lucite collector lenses for the dark field illumination. The objective threads are actually turned into the lucite eliminating the need for a special large-thread objective � all threads are standard RMS 20mm. One port is vacant. The three 215mm tubelength objectives include:

8x / 0.20 � working distance 0.530 inches, largest field-of-view 0.093 inches
20x / 0.40 � working distance 0.035 inches, largest field-of-view 0.036 inches
40x / 0.65 � working distance 0.030 inches, largest field-of-view 0.018 inches

As far as it goes, the stand is in really fine condition cosmetically. The microscope body has been completely rebuilt so the binocular portion interpupillary system works smoothly as well as the zoom mechanism and the viewing port selector. Binocular alignment was touched up so both eyepieces are perfectly coincident. Regarding mechanical condition, the fine focus adjustment is a bit stiff, but functional. It should be relubricated for best functionality � sometimes the stiffness is such that the coarse adjustment knob begins to turn along with the fine. The coarse adjustment is working very well. Optically, the diaphragms in the Trivert illuminator are not perfectly aligned nor are the objectives exactly parfocal. I will leave it up to the purchaser to correct these things should they wish to do so.

The post Bausch and Lomb EM-14 Dynazoom Trinocular Microscope appeared first on BMI Surplus.

This is a wonderful example of a classic Bausch & Lomb Dynazoom microscope that is adapted for the examination of thicker opaque materials. The stand has been slightly modified by the addition of a spacer block which raises the limb about an inch higher from the base. The stage carrier has been modified so the stage sits a similar distance further from the viewing head, thus providing extra room for the vertical illuminator assembly.

These microscopes are very modular, so it is helpful to state how they are configured. The stand itself features a low-set coaxial coarse and fine adjustment mechanism that is comfortable to use with the hands resting on the table surface. The XY mechanical stage has low-set coaxial control knobs and a pair of removable specimen holders for an unobstructed stage surface. The stage has the rack & pinion substage assembly that is provided with an Abbe condenser with aperture iris.

The base of the stand includes an optional hi-intensity illumination housing with a lamp socket. This housing has a centerable field iris diaphragm with built-in filter recess. There is no transformer for the transmitted light illumination, it will need to be sourced elsewhere.

Called the 'Trivert', it has provisions for bright field, dark field, and (when so optioned) polarized light. Please note that no polarized light accessories are included with the equipment! The illuminator has separate field and aperture diaphragms and a slot for receiving filters. A pre-centered GE 1630 lamp provides more-than-adequate light intensity. The lamp includes a Jeffey transformer with continuously regulating transformer. A selector knob next to the beam-splitter swings in a central stop for observations in dark field (field and aperture diaphragms must be fully opened).

40x / 0.65 � working distance 0.030 inches, largest field-of-view 0.018 inches

The stand is in near-flawless condition cosmetically. The microscope body has been completely rebuilt so the binocular portion interpupillary system works smoothly as well as the zoom mechanism and the viewing port selector. Binocular alignment was touched up so both eyepieces are perfectly coincident. Regarding mechanical condition, the fine focus adjustment is fully functional and turns easily, but feels a bit 'dry'. The coarse adjustment works very smoothly. Both stage controls work smoothly. The only optical 'issues' are the alignment of the diaphragms in the Trivert illuminator. Unless one slightly stops down the field diaphragm (still outside the viewing field, however), there is an annoying halo that appears during dark field observations. This halo is also present in bright field but is less obvious. Slightly stopping down the field diaphragm appears to block this spurious illumination. The objectives are not perfectly parfocal. However, the microscope works well the way it sits. All optical surfaces are in perfect condition.

This is another wonderful example of a classic Bausch & Lomb Dynazoom microscope that is adapted for the examination of thicker opaque materials. The stand has been slightly modified by the addition of a spacer block which raises the limb about an inch higher from the base. The stage carrier has been modified so the stage sits a similar distance further from the viewing head, thus providing extra room for the vertical illuminator assembly. The excursion of the stage is such that a specer is needed to lift the sample high enough so it may be focused by the objectives. Minimum distance between the stage and 'focal plane' is about 10mm.

These microscopes are very modular, so it is helpful to state how they are configured. The stand itself features a low-set coaxial coarse and fine adjustment mechanism that is comfortable to use with the hands resting on the table surface. The XY mechanical stage has low-set coaxial control knobs and a pair of removable specimen holders for an unobstructed stage surface. This stage carrier has no provision for a substage system and the base of the stand has cover plates installed where the transmitted light illumination system would otherwise go.

The stand is provided with the most elaborate version of the many tubes that were available for this instrument. This microscope tube has binocular observation and a control knob to switch the light path into a port on the top of the tube. It also features a 1x to 2x continuous zoom mechanism that operates in both the photo and binocular ports. The zoom knob is graduated. The microscope pod may be turned through 180 degrees so the limb of the stand may either be away from or close to the observer (the vertical illuminator prevents continuous rotation).

The stand is in superb condition cosmetically. The microscope body has been completely rebuilt so the binocular portion interpupillary system works smoothly as well as the zoom mechanism and the viewing port selector. Binocular alignment was touched up so both eyepieces are perfectly coincident. Focus mechanism and stage controls both work very smoothly. Optically, the stand is in superb condition, however there is some minor misalignment of the field and aperture diaphragms in the vertical illuminator. Images are still excellent and I will leave it up to the purchaser as to whether he wishes to address that issue.

The Model 1860 Industrial Microscope stand has a very large yoke and is able to accommodate stages with up to 6 by 6 inches of travel. The stage is rigidly clamped to the microscope base and does not move during focusing. Instead, the nosepiece carrying the objectives is the only part that moves. The infinity corrected optics of the system allow moving the objectives relative to the rest of the stand without any loss in optical corrections.

The stand has a special super-long-life 20w halogen lamp (life rated at 10,000 hours) that is situated at the back of the stand. A filter turret has four positions � one open, one diffusion disk, a daylight blue filter, and a strong green filter. A fully adjustable field iris is situated just forward of the filter turret.. The illumination train has a swing-out beam-splitter used for brightfield vertical illumination. When swung to one side using the lever on the right side of the microscope, the illumination flux is directed to an annular mirror just above the revolving nosepiece. The nosepiece will accommodate five objectives using RMS threads. The continuously regulating transformer is built into the base of the stand.

The stand includes a trinocular microscope tube, type 1103. This tube is a Seidentoph arrangement so tube length remains constant no matter what the setting of the interpupillary distance. A lever switches the image between the binocular and the phototube port. It is also possible to mount an optional image erection tube (type 3002) between the microscope stand and the observation tube. This tube is not included but is available as a separate item on our website..

The stand and tube are in excellent condition and fully functional. Please note that the microscope does not include the stage, stage mounting bracket, or any optics. Please check our website for availability of these items.
