  • Hewlett Packard 10700A 33% Splitter

    $105.00

    This item is an HP 10700A 33% Beam Splitter. It is a basic component of the Hewlett Packard Laser Interferometry Distance Measuring Apparatus. It is one of several components based on a 1� steel cube. The cube has a beam-splitting reflector set at 45-degrees and face-centered to three adjacent faces. The mirror surface is coated. These components are useful when it is desired to have three axes tied to a single laser (each axis will require its own interferometer and detector, however). The first beam-splitter in the system would be the 33% splitter, leaving roughly 66% of the beam to travel to a second 50% beam-splitter for the other two axes. In that manner each receiver will be working at approximately the same power level.
    , 2nd Grade
    The angle of the beam-splitter is not critically set within the cube in order to keep component prices reasonable. For precise positioning it is recommended that the beam-splitter is fixtured using a small leveling base (HP 10710A). These mounts allow for corrections in two directions. Pitch may be adjusted through several degrees about the axis of the mirror component by resetting the cradle position in the base, and yaw may be adjusted using the play in the elongated slots for securing the base. The base of the mount has an open aperture so the beam path may be directed through the base of the fixture. Beams should ONLY be deflected at right angles in each laser / detector assembly in order to avoid depolarization of the laser beams. Beams can be deflected through an aperture in the base of the mount for utmost versatility.

    These components have been removed from various fixtures. They meet our requirements for second quality used interferometer components. All optical surfaces are free of serious blemishes and there are no gouges or distortions in any of the parts that would in any way impede accuracy of measurements. Cosmetically these components appear in very fine condition, although not new. Unlike new components, no hardware is included.

  • Insp L Objective from Small Nikon Profile

    $20.00

    This is a specialized objective lens taken from a modest-sized Nikon Profile projector. It is engraved merely ‘Insp. L.’ – no magnification or any other marks on the lens. The projector was woefully incomplete and was parted out some time ago.

    Cosmetic condition of the barrel is very good – however the lens itself does suffer from numerous fine scratches from careless cleaning (last photo shows them much more pronounced than they actually are – the wonders of digital photography). The objective thread is 28.1 mm in diameter – rather odd. . . � We are also offering the other objectives from this projector as well as the original turret. Please check our other listings.

The stage runs on opposing single-row ball bearings in captive cages. Klinger model number including the spindle is 338 070. These stages differ from the MRS stages in that they do have restoring springs installed and one of the two end plates is threaded to receive a micrometer spindle.

    Overall length of upper platform � 92mm
    Overall width of upper platform � 80mm
    Height of platform � 18.5mm
    Fixed mounting plate 0.5mm proud of moving platform
    Fixed platform area � 53mm long by 53.6mm wide
    Aperture clearance � 35mm diameter
    Straightness � better than 200 micro radians

    The stage is in excellent condition both mechanically and cosmetically.

  • Oriel 17701 Adjustable 2 inch Mirror Mount

    $210.00

    This is a Oriel 17701 Adjustable 2 inch Mirror Mount.

    This item is an Oriel High Precision Mirror Mount, model 17701. The mount will accept mirrors of 50mm diameter and up to � inch thickness. There are two orthogonal motions that are completely independent of each other. The range of motion is 4 degrees for each axis. The controls are side mounted so it is easy to adjust them without disturbing the optical path. Sensitivity (resolution) for each axis is 0.1 arc seconds. The mounts are very temperature stable – the leadscrew for adjustment of the axes are designed with a similar coefficient of expansion to the aluminum used in the mounts themselves.

    The mirror mount is only about 5 1/8� wide including the adjustment knobs. Clear aperture with the mount at a 45 degree angle is 0.55�.

    This mounting is in very fine condition – both axes work perfectly. The mounts may have signs of modest use.

    Photo set 1630.

  • Tropel 9000 Laser Interferometer

    Call 781-871-8868 for Price

    This is a Tropel Model 9000 laser interferometer. It is used for checking the flatness of wafers and masks up to 5 inches in diameter. It uses a HeNe laser as a monochromatic source, and has a built-in video camera for fringe display on a Sony Black & White monitor.

    The interferometer is in spectacular condition with the exception of a small scratch near the upper center of the reference prism (outside the field of view of all but the largest wafers). The wafers are held in place by a vacuum chuck and fringe spacing and direction is adjusted via three very fine setting screws located to either side and beneath the chuck holder.

    The interferometer includes the following chucks:
    � 2 inch vacuum chuck
    � 3 inch vacuum chuck
    � 4 inch vacuum chuck
    � 5 inch ‘bow’ chuck
