Jarrell Ash Adjustable Slit with Micrometer Actuator.

This is a fully reconditioned adjustable slit from a one-meter Jarrell-Ash double monochromator..
The slit is mounted on a cylindrical sleeve 1.5 inches in diameter.
The sleeve has a threaded focusing disk which would be held captive in the monochromator (the holding assembly is not included).
There is a micrometer drum for governing the slit width.
The micrometer reads ‘0’ when the slit just closes.

Enclosure size (for slit) � 100mm wide, 58mm tall, 25mm deep
Maximum slit opening � 4mm
Micrometer reads to 0.02mm
Calibrated adjustable mask for governing slit height � zero to 20mm plus four additional 2mm square apertures at differing heights

The mechanism works perfectly. When knife edges meet micrometer reads zero. Cosmetic condition is superb.

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.

This is an unusual accessory for the McPherson Model 218 UV � Vacuum Scanning Monochromator.
It is a camera attachment for use with pieces of specially cut film. The film may be translated vertically (parallel to the slit) via a micrometer spindle.
The film is exposed via a simple sliding shutter arrangement.

In order to install the attachment, it is necessary to remove the knife-edge slit system from the exit port of the monochromator. This modification is something that may not be easily reversed.

The camera attachment is in excellent and fully functional condition, although very obsolete.
