Spex Paired 1 Meter Monochromator Mirrors
Spex Paired 1 Meter Monochromator Mirrors.
This is a pair of spherical mirrors of 5 inch diameter mounted on a common carrier.
They are not marked but it is certain that they were removed from a SPEX monochromator.
Radius of curvature was not measured, but it is probable the monochromator was either 750mm or 1 meter focal length.
Both mirrors are provided with adjustments for setting azimuth and elevation.
The carrier base is 6 inches wide and 4 inches long. It has a 0.75 inch wide guide slot and a screw for positioning the base within the monochromator (see third photo).
The mirrors appear to be aluminum coated. They are in excellent condition, but there is a very light haze in portions of the coating, and a few very minor coating blemishes. We did not attempt to clean the mirrors.

Unitron Multibeam Interference Objective,
This is a most interesting microscope objective. It is intended for use in reflected light applications for the quantitative study of surface finish or very small-scale step height profiles. The objective is a complete multi-beam interferometer. The objective threads into the microscope nosepiece like a normal lens. The front of the objective is threaded and carries a small interchangeable reflective beam-splitter. Once the sample is focused, the beam-splitter may be lowered until it touches the sample. Contact with the sample produces interference fringes that relay information about the surface topography of the sample.
The beam-splitter mirror included with the objective is marked ‘FLAT’, and appears to have a reflection coating of approximately 60%. In practice, it is best to come close to matching the reflectivity of the sample to that of the beam-splitter. For highly reflective samples, such as mirrors and silicon wafers, the nominal beam-splitter value would be closer to 90%.
The surface of the reference mirror appears to be free of scratches, however the reflective beam-splitter surface has several voids. Fringes will still be seen in these areas, but they will be far fainter. It would be best to have the mirror re-coated. Because of the contact nature of this type of interference, and the fact that the reference mirror is rotating is it is brought to bear on the sample, exceptional care should be exercised when employing this type of objective. Ideally, the mirror should be ‘pre-focused’ � easily done using the voids in the surface, then the fine focus of the microscope used to bring the sample to the proper position. Samples should never be scanned when the interferometer plate is touching the sample!
The reference mirror cannot be tilted independently of the optic axis, so it would helpful if the sample were supported on some sort of cup-bearing stage with very fine tilt adjustments. This would enable one to adjust the spacing and the direction of the fringes. Also required for fringe coherence and measurements would be a precision line filter or a spectral lamp source of known wavelength. We have several different monochromatic filters available. Please inquire!

Jarrell Ash Rectangular Mirror from
This is one of a pair of collimation mirrors removed from a 50cm Jarrell-Ash monochromator. The mirrors have the following characteristics.
Size � 84.15mm x 68.07mm
Thickness (at corners) � 17.5mm
Focal length � approximately 515mm
Coating � Al
The mirrors coatings are in rough shape. These will need to be recoated before they are useful. Substrate appears to be undamaged (one of the two mirrors has a very small corner chip that does not impinge upon the coated area). This listing is for a single mirror.

American Holgraphic SP00298-01 Hyperspectral Imaging
American Holgraphic SP00298-01 Hyperspectral Imaging.
When we got this instrument it was covered in reflective tape � obviously prepped for some spacecraft or high-altitude mission. There are no adjustments to the monochromator, so there must have been a camera system that acquired the spectrum. The slit is fixed in one position and not adjustable in width. It appears to be about 0.1mm wide (rough estimate). The system appears to be in near-perfect condition, however, there are a couple of rub marks on one of the collimation mirrors near the margin.
There is a circular mounting plate that I assume held the acquisition system. There are a few degrees of freedom in the alignment of the plate. The slit is in the base of the monochromator (as seen in the first photo) whereupon the light is directed to a mirror that sends it to the first collimation mirror. The grating element itself is just beneath the large aperture facing forward in the second photo. The grating substrate is convex and fixed in place. It appears to be about 25 to 30mm in diameter (I did not open up the instrument), and the two collimation mirrors appear to be about 75mm in diameter � again, just an estimate. The second collimation mirror directs the spectrum to the camera port.
There is a sticker on the instrument that identifies the manufacturer as �American Holographic�. The same sticker identifies the item as a catalog SP00298-01, serial number M2-016.

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