  • Mounted 2X Anamorphic Prism Pair, 780 – 1550 nm

    $175.00

    Mounted 2X Anamorphic Prism Pair, 780 – 1550 nm

    This anamorphic prism pair in a cylindrical mount is used to magnify a laser beam diameter in only one axis by a factor of 2x. Although not marked on the barrel, this was determined to be the prism pair used for the wavelength range of 780 to 1550nm by measuring the beam offset of the mount which was 5.7mm. (The only other 2x prism pair offered by Melles Griot has a 5.lmm offset).

    The polarization state of the laser beam is unaltered. The prisms are coated to minimize reflection losses. Beam deviation may be altered by up to one degree, typically less. The output side of the housing is counterbored to accommodate interchangeable diode laser objectives in mounted cells (not included).

    Input beam diameter can be up to 8 x 4mm. Outer black-anodized aluminum housing diameter is 30.15mm. Length is 38.1mm. Wavefront error held to less than � wave at 830nm.

    The prism system is in superb condition both optically and cosmetically. The set screw for retaining the optional objective is absent.

  • Anamorphic Laser Beam Prism Pair 2.2x at 820nm

    $149.00

    This device is used to selectively amplify an image (or beam) in one direction while leaving the orthogonal direction unchanged. A typical application is that of laser diodes in which the output beam cross-section is elliptical instead of circular. By suitable arrangement of a pair of triangular prism wedges, various anamorphic magnification ratios can be established.

    One consequence of this modulation is that the output beam, while parallel to the input beam, is offset relative to the input beam in the direction of the modulation. Special Optics have housed these prism pairs in sturdy black anodized aluminum cells. The input and output faces are threaded with the proper amount of offset relative to each other.

    � Anamorphic magnification – 2.2x
    � Beam offset – ~5mm
    � Antireflection coating 820 nm
    � Part number – 18-2009
    � Thread inside diameter – 1.08 inches
    � Base dimensions – 2.25 inches wide, 2.11 inches long
    � Centerline height, including base – approximately 1 inch

    These prisms housings do show very light signs of previous use, but the glass appears to be without flaws.
