Unknown Salt Window ~1.550 inches by < 0.25
$60.00This lot consists of two windows of an unknown salt crystal. They are suspended inside fiberboard tubes by slightly smaller tubes inserted into either side of the larger tube. I did not wish to remove the tubes, so I can only guess at the thickness, being on the order of 0.15 to 0.25 inches. The diameter is less than 1.6 inches, and may be as small as 1.550 inches. The crystal windows are in excellent condition � I could not detect any degradation. The outer tubes are lined with desiccant packages. There appear to be two identical windows � unfortunately, no markings as to compound, or dimensions. Listing includes both pieces.

Ealing 50mm Diameter Neutral Density Filter Set
$400.00This is a very nice selection of Ealing neutral density filters. All the filters are 50mm in diameter, five of which have plastic cells. Clear aperture of the filters within the cells is 40mm. The filters appear to have a quartz substrate (they are very light, and Ealing typically used quartz for their reflective neutral density filters). Two filters do not have the plastic rings, nor is their any indication of transmission directly on the filters, however there are labels in the cabinet that match the transmission characteristics observed in the filters.
The list of filters includes
ND 0.1 � no cell, reflective type
ND 0.3 � in Ealing Cell, reflective type
ND 0.6 � in Ealing Cell, reflective type
ND 1.0 � in Ealing Cell, reflective type
ND 2.0 � in Ealing Cell, reflective type
ND 3.0 � in Ealing Cell, reflective type
ND 4.0 � no cell, reflective type, sandwichedAll of the filters are in perfect condition with the exception of the ND 3.0, which appears to have several microscopic pin-holes. There is also a darkish blemish on the surface of the filter (visible in the third photo), but this does not seem to show up in transmitted light. The filters are supplied in a nice fitted walnut cabinet with elastic retaining bands. There are no transmission curves for any of the filters.

Laser Precision Power Meter RT20C
$100.00This is a Laser Power Monitor manufactured by Laser Precision Corporation. This particular model is an RT-20C with an analog readout.
PLEASE NOTE: this listing includes ONLY the indicator unit � the BNC cable and detector shown in the photos belong to another instrument
Front panel controls include the power switch, a �set zero� multi-turn pot for dark current compensation, and a selector switch for meter range. Full scale is adjustable in a 1 � 3 � 10 sequence from 10mW to 30 Watts. Output indication of the detector perfectly matched that obtained with the digital meter (13mW).
The rear panel has banana plug jacks for recorder output, line input selector switch, input for BNC cable from detector, fuse holder, and line cord.
The system was tested with a 15mW HeNe laser with the range selector set to 30mW. The reading was 13mW and this varied slightly depending on the position of the laser on the detector. Detector area is about 20mm in diameter. I did not adjust the calibration pot.
The meter was functioning properly when put into storage at our facility, although it was not tested with a higher power laser. No documentation is supplied. Cosmetic condition is outstanding.

CVI Laser Corp. 2-inch Mirror Mount
$85.00This item is a CVI Laser Corporation mirror mount for 2 inch optics. It is not a true gimbal mount � the tilting plate is referenced against a large ball bearing in one corner of the mount, and the adjacent corners bear against a pair of micrometer spindles.
These mounts are quite compact � the overall size of the tilting plate is only 4 by 4 inches, with an additional 0.125 inches provided as a reference surface for the optional mounting plate (not included with these mounts).
Range of tilting motion in both the azimuth and elevation axes is on the order of plus or minus 2 degrees. The recess for the mirror is 0.465 inches deep and is threaded for a retaining ring. The retainer rings are not included with the mounts. Mirrors thinner than 0.200 inches require a shim. Diameter of the recess is 2.005 inches.
The mounts are only about 1.125 inches in thickness, and use special stubby micrometer spindles to minimize the mount footprint. Total thickness of the assembly with the micrometer heads is only about 2.650 inches.
The mounts are in very good condition. The anodizing on some of them has faded more than on others, but mechanically they are in perfect functional condition.

Dimensions of the foot are 4 inches wide by 2.63 inches deep. The foot is configured in a manner that the front does not extend beyond the optic mounting plate.
The mounts are in very good condition. The anodizing on some of them has faded more than on others, but mechanically they are in perfect functional condition.

Spectra-Physics / Coherent 2-inch Mirror
$75.00This item is a Spectra Physics / Coherent mirror mount for 2 inch optics. It is not a true gimbal mount � the tilting plate is referenced against a large ball bearing in one corner of the mount, and the adjacent corners against a pair of micrometer spindles.
These mounts are quite compact � the overall size of the tilting plate is only 3.75 by 3.75 inches, with an additional 0.125 inches provided as a reference surface for an optional mounting plate (not included with these mounts).
Range of tilting motion in both the azimuth and elevation axes is on the order of plus or minus 2 degrees. The retaining cell for the mirror will accommodate mirrors up to 0.500 inches in thickness, and of 2 inches diameter. Mirrors thinner than 0.250 inches will require some sort of shim.
The mounts are only about 1.125 inches in thickness, and use special stubby micrometer spindles to minimize the mount footprint. Total thickness of the assembly with the micrometer heads is only about 2.500 inches.
The mounts are in very good condition. The anodizing on some of them has faded more than on others, but mechanically they are in perfect functional condition. The mounts DO NOT include the plastic threaded retaining rings for the mirrors

Spectra-Physics / Coherent 2-inch Mirror
$145.00This item is a Spectra Physics / Coherent mirror mount for 2 inch optics. It is not a true gimbal mount � the tilting plate is referenced against a large ball bearing in one corner of the mount, and the adjacent corners against a pair of micrometer spindles.
These mounts are quite compact � the overall size of the tilting plate is only 3.75 by 3.75 inches, and the supporting plate adds an additional 0.625 inches to the nominal optic axis height (2.500 inches with base included).
Range of tilting motion in both the azimuth and elevation axes is on the order of plus or minus 2 degrees. The retaining cell for the mirror will accommodate mirrors up to 0.500 inches in thickness, and of 2 inches diameter. Mirrors thinner than 0.250 inches will require some sort of shim.
The mounts are only about 1.125 inches in thickness, and use special stubby micrometer spindles to minimize the mount footprint. The baseplate is 2.375 inches deep, and 2. 813 inches wide. It is secured to the carrier plate in such a way that the front of the mount is still proud of the front of the base.
The mounts are in very good condition. The anodizing on some of them has faded more than on others, but mechanically they are in perfect functional condition. All include the mirror retaining rings.
