  • 2-inch Gimbal Mount less Lens Holder, less Bracket

    $120.00

    This is a Burleigh gimbal mount for optics or mirrors of 2 inches diameter. It is a true gimbal – both the azimuth and elevation axes are co-planar with the front surface of the mirror cell. The mounts are exquisitely made from three basic castings – two for each of the gimbal planes and one for the supporting plate. There are three basic subassemblies to the mounts. The gimbal mount with the micrometer spindles; the removable optic carrier mount; and the angle support plate. This mount lacks the optic carrier and the angle support plate.

    This version is a bit earlier – the micrometer spindles lack the large plastic adjustment rings for increased setting sensitivity. Each axis has internal springs to keep the gimbal plates in contact with the micrometer spindles, and in addition, a spring-loaded plunger to augment stability. The position of the plunger can easily be changed so it will be effective in the range of motion required.

    The removable optic carrier is missing from this mount – currently there is a clear bore of 2.255 inches diameter. One could easily fabricate a mirror holder to fit the bore.

    Dimensions:

    � Gimbal support plate – 4 inches wide, 4.75 inches tall (0.500 inches thick)
    � Optic axis height = 2 inches
    � Range of motion (azimuth and elevation) – approximately plus or minus 2 degrees
    � Modified Starrett 263 micrometers with large thimble rings
    � Overall depth with micrometers – 4 inches
    � Minimum / Maximum mirror thickness – 0.25 / 0.60 inches.

    Condition of everything is superb. The mounts have been rebuilt and the micrometer spindles cleaned and relubricated. This version of the mount is cast of light aluminum alloy as opposed to steel. Please note that the elevation spring plunger missing in the photos has been replaced!

  • Burleigh 2-inch Gimbal Mount with Elevation

    $275.00

    This is a Burleigh gimbal mount for optics or mirrors of 2 inches diameter. It is a true gimbal – both the azimuth and elevation axes are co-planar with the front surface of the mirror cell. The mounts are exquisitely made from three basic castings – two for each of the gimbal planes and one for the supporting plate. There are three basic subassemblies to the mounts. The gimbal mount with the micrometer spindles; the removable optic carrier mount; and the angle support plate. These mounts all come complete with all three components.

    This mount includes a special Piezo actuator bearing pad for the elevation micrometer. The actuator does not include the connection cable or the control unit to ramp the Piezo. The special Piezo system allows extraordinary positional sensitivity.

    Both axes have internal springs to keep the gimbal plates in contact with the micrometer spindles, and in addition, a spring-loaded plunger to augment stability. The position of the plunger can easily be changed so it will be effective in the range of motion required.

    The second assembly is the optic cell. This entire assembly is held in place by a large knurled collar from the back. It is possible to remove the cell from the gimbal mount in order to install the optic of interest. The cell is designed so the reference plane of the mirror sits precisely in the gimbal plane. The front of the cell is chamfered so almost the entire mirror surface may be used when the incident light angle is less than or equal to 45 degrees. The cell will accept mirrors between 0.25 and 0.50 inches in thickness without additional spacers (thinner mirrors require spacer rings). The optic carrier includes a threaded retaining ring for the mirror.

    The last component is a right-angle bracket for attaching the gimbal mount to a table. The gimbal mounting support plate attaches to the bracket with four Allen cap screws.

    Dimensions:

    � Gimbal support plate – 4 inches wide, 4.75 inches tall (0.500 inches thick)
    � Optic axis height = 2 inches
    � Range of motion (azimuth and elevation) – approximately plus or minus 2 degrees
    � Modified Starrett 263 micrometers with large thimble rings
    � Overall depth with micrometers – 4 inches
    � Minimum / Maximum mirror thickness – 0.25 / 0.60 inches.

    The base plate adapter (right-angle bracket) raises the optic axis height to 2.375 inches. Overall baseplate dimensions are 4 by 4 inches. The reference plane lies approximately 0.875 inches from the front of the base plate.

    Listing includes gimbal mount, 2 inch optic cell with retainer, support bracket and Piezo units. Condition of everything is superb. The mounts have been rebuilt and the micrometer spindles cleaned and relubricated. The gimbal plates in these mounts are cast steel, not the much lighter aluminum alloy.

The gimbal mount with the micrometer spindles; the removable optic carrier mount; and the angle support plate. These mounts all come complete with all three components.

    The micrometer spindles have large diameter plastic rings attached to the spindle drum to make it easier to accomplish very precise adjustments.

  • Cylindrical Lens, +100mm f.l., Unmounted

    $50.00

    This is a plano-cylindrical lens. These lenses have a defined magnification in one direction, and perpendicular to that direction they are effectively ‘unpowered’. Cylindrical lenses find numerous applications in holography, as well as imaging elongated slits in spectrometers and monochromators.

    Characteristics of this lens include:
    � Focal length – Positive 100mm
    � Length – 40mm
    � Width – 25mm
    � Manufacturer – Unknown
    � Part number – Unknown
    � Glass type – BK7 ?
    � Uncoated
    � Condition – no visible defects

    Please note – unless we are able to determine that a lens is a higher precision type (either by part number or by nomenclature on the lens itself) then it should be assumed that the lens has a low precision figure. When we have determined that a lens is definitely a low precision grade, then that will be stated in the lens characteristics.

    Please note – unless we are able to determine that a lens is a higher precision type (either by part number or by nomenclature on the lens itself) then it should be assumed that the lens has a low precision figure. When we have determined that a lens is definitely a low precision grade, then that will be stated in the lens characteristics.

    This lens has been mounted in a circular cell, 52mm in diameter. This cell is in turn mounted in an outer ring of 65mm diameter. The clear central aperture of the inner lens support is 18mm.

  • Cylindrical Lens, +40mm f.l., Mounted

    $55.00

    This is a plano-cylindrical lens. These lenses have a defined magnification in one direction, and perpendicular to that direction they are effectively ‘unpowered’. Cylindrical lenses find numerous applications in holography, as well as imaging elongated slits in spectrometers and monochromators.

    Characteristics of this lens include:
    � Focal length – Positive 40mm
    � Length – 40mm (cut down)
    � Width – 25mm
    � Manufacturer – Unknown
    � Part number – Unknown
    � Glass type – BK7 ?
    � Uncoated
    � Condition – no visible defects

When we have determined that a lens is definitely a low precision grade, then that will be stated in the lens characteristics.

    This lens is mounted in a nested ring mount. The inner ring is 54mm in diameter with a 40mm central aperture. There is a cover plate to bridge the milled gap for the lens. This cell in turn fits into another ring 60mm in diameter.
