Eppley Thermopiles Set of Two with Manual
$500.00This set of Eppley Thermopiles came from a working environment but have not been tested.
Please call us for more information.From manual: One of the earliest devices employed to measure radiant energy was the thermopile. A circular and linear type of thermopile were introduced by W. W. Coblentz who subsequently arranged with the Eppley Laboratory for their commercial manufacture and improvements. In principle, they are have been referred to as �compensated thermopiles�, which applies to their thermal compensation where the total area (mass) of the shielded cold receivers is equal to that of the single hot receiver.

Custom Pellicle Neutral Density Filter, 2 Inch
$40.00This is an unusual neutral density filter on a wafer-thin glass substrate. The optical density is marked on the surface of the filter (0.96) in blue ink. I have not attempted to remove the marking. The filter is very uniform in density (the gradation visible in the photo is an artifact of the lighting). There are a few fine scratches in the coating near the edge with the marking. There is also a fine scratch in the glass on the side opposite the coating (see second photo). It extends most of the way across the filter.

Newport HVM-.5 Vertical Drive Kinematic Optical
$85.00This item is a used Newport HVM-.5 Vertical Drive Kinematic Optical Mount in excellent working condition.
From manufacturer website: The HVM-.5 Vertical Drive Kinematic Optical Mount is unlike any optical mount in its class. The HVM�s unique ball-and-wedge drive mechanism enhances the overall performance of the 1/2 inch (12.7mm) diameter optical mount by reducing stiction and backlash to negligible levels while maintaining a compact and robust package. This unique drive mechanism also allows substantial angular tilt without adjustment screws protruding from the back of the mount, where fingers can block the beam. At a scant 0.68 inch thickness the HVM can be placed in optical systems requiring minimum footprint. Newport�s in-line spring mechanism provides targeted tension at appropriate points to ensure the HVM is stable both short-term and long-term. The high resolution adjustment screws have a locking mechanism to prevent inadvertent adjustment. This same mechanism provides the ability to customize the feel/tension of each adjustment.

American Holgraphic SP00298-01 Hyperspectral Imaging
$575.00American 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.

Newport BUP-2 Universal Base
$30.00This used Newport BUP-2 Universal Base is in good working condition. This unit is missing one (1) of the ball bearings.
From manufacturer website: Newport�s BUP-2 Universal Base incorporates a patented mounting device that gives unprecedented positioning flexibility. A freely rotating disk, inset into each base, has an eccentric clearance slot to accommodate a 1/4-20 or M6 tie-down bolt. This single bolt firmly clamps the assembly to your table surface. The slot permits 0.707 in. of translation � at least half the diagonal distance between holes in Newport�s English and metric tables, breadboards and mounting components like lab jacks and stages. Thus it is always possible to find a mounting hole through the clearance slot by rotating the trapped disc; the bases can be freely positioned anywhere, at any orientation, on your table surface

Broadband Metallic Mirror, Pyrex, 50.8 mm Diameter
$110.00This item is a new Newport 20D20ER.2 Broadband Metallic Mirror.
From Manufacturer Website: The 20D20ER.2 Broadband Metallic Mirror is an excellent general purpose, broadband reflector. This 2 inch (50.8 mm) diameter mirror is made from a 12.7 mm thick Pyrex substrate. Pyrex has low thermal expansion and is an excellent substrate for most applications. The ER.2 protected silver coating is composed of a low emissivity silver film fully encapsulated by a multilayer dielectric stack to prevent oxidation. This coating has excellent broadband reflectivity in the IR, while maintaining very good performance in the visible and near IR. Average reflectivity is greater than 96% from 480�1100 nm and greater than 98.5% from 1.1�20 um. This mirror has a 1/10 wave surface flatness and a 15-5 surface quality.

Camera Attachment with Micrometer Displacement
$300.00This 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.
