Chroma Dichroic, Band Stop 460 ? 600nm, lines
$100.00This Chroma filter is in decent condition, having been removed from some prototype equipment. It has the following characteristics:
� Dimensions = 25mm x 18mm
� Thickness = 3mm
� No mounting cell
� Filter type – interference dichroic
� Part number – 625DCXRThe filter appears to be dual-excitation dichroic. The wavelength characteristics are rather complicated. There is a sharp band stop region that extends from 460nm to 600nm, with transmission lines at 554 and 567nm
Transmission characteristics are measured with the filter mounted at 45 degrees to the optic axis. The reflection characteristics are complementary to the transmission characteristics. The edges of the filter may have a bit of the coating missing (photo is typical), but the central region of the filter is excellent.

Chroma Dichroic Band Stop 460 – 600nm lines at 554 and 567nm
$120.00Chroma Dichroic Band Stop 460 – 600nm lines at 554 and 567nm.
This Chroma filter is in very good condition, having been removed from some prototype equipment. It has the following characteristics:� Diameter = 25mm
� Thickness = 2mm
� No mounting cell
� Filter type – interference dichroic
� Part number – 625DCXRThe filter appears to be dual-excitation dichroic. The wavelength characteristics are rather complicated. There is a sharp band stop region that extends from 460nm to 600nm, with transmission lines at 554 and 567nm.
Transmission characteristics are measured with the filter mounted at 45 degrees to the optic axis. The reflection characteristics are complementary to the transmission characteristics. The surface of the filter may have a very fine void or two, but the ‘mottled’ appearance in the photo is actually a reflection artifact – the filter coating is very even.

Chroma Dichroic Filter Band Stop 490 ? 525nm
$140.00Chroma Dichroic Filter Band Stop 490 ? 525nm.
This Chroma filter, in excellent condition, has the following characteristics:
� Diameter = 25mm
� Thickness = 3mm
� Free aperture = 23mm
� No mounting cell
� Filter type – interference, with high-Q stop bandBandpass characteristics were measured with the filter at 45 degrees to optic axis. This filter appears to block the spectral region between 490nm and 525nm. Reflected color in photo appears ‘wrong’ because it was taken normal to optic axis. If needed, I can measure characteristics at normal to optic axis.

Chroma Dichroic Filter, Multiband, 450-465, >478,
$160.00This Chroma filter is in excellent condition, having been removed from some prototype equipment. It has the following characteristics:
� Dimensions = 25mm x 18mm
� Thickness = 3mm
� No mounting cell
� Filter type – interference dichroicThe filter appears to be dual-excitation dichroic. The wavelength characteristics are rather complicated. There is a sharp bandpass region that extends from 450 to 465nm. Then again, starting at 478nm it behaves for the most part like a long-pass filter. In addition, there are two very strong blocking lines at 538nm and 633nm.
Transmission characteristics are measured with the filter mounted at 45 degrees to the optic axis. The reflection characteristics are complementary to the transmission characteristics. The part number of the filter is not known. There is a bit of mounting medium (appears to be silicone) still clinging to the edge of the filter. Filter surface is free of blemishes.

Klinger 1-inch Gimbal Mount
$280.00Klinger 1-inch Gimbal Mount BM micrometer
This item is a Klinger (also known as Micro-Controle, and now manufactured by Newport) SL type Gimbal optic mount. The SL gimbals are characterized by massive steel construction with two mounting flats for orthogonal positioning of the tilting axes so the controls are on the right or left side of the beam path. The two planes of tilt perfectly intersect the plane of the optic (often a mirror) so adjusting azimuth or elevation results in the reflection point always being stationary on the optic axis. The elements are held in place by a spring-loaded ring. There are three small bearing points to precisely locate the optic in the main yoke, and another three within the spring-loaded clamping ring. The securing screws are not quite symmetrically placed to aid in removal of elements through the slightly larger opening.
This particular gimbal mount uses the standard �BM� type micrometer. Readings do not correspond to angular rotation, but they are repeatable, and graduated to 10 microns (sensitivity of setting is approximately 1 micron).
Specification on this particular gimbal mount include:
Optic diameter � 25mm
Optic thickness � between 1 and 12.5mm
Outside diameter � 89mm
Clear aperture of mount � 21mm
Approximate thickness of mount � 30mm (less micrometers)
Angular adjustment range � plus /minus 3 degreesThe mount is in excellent condition � micrometers fully functional throughout range. There is a small hole drilled in one of the base flats (see photo). The mounts do NOT come with the adapter plate. Those are listed independently as SKU number DP252 (they are only available with the purchase of a matching type gimbal).
