Newport 10RP32 -532 Wave Plate
$500.00Unit is a Newport 10RP32-532 zero-order precision wave plate.
Specifications:
-Diameter 25.4mm
-Wavelength: 532nm
-Thickness: 6.35mm..Manufactures description:
The 10RP32-532 True Zero-Order Wave Plate consists of a birefringent polymer film cemented between two high-precision, high efficiency, broadband antireflection coated BK 7 windows. This construction ensures excellent transmitted 532 nm wavefront quality and /2 retardation, while minimizing beam deviation and surface reflection losses. The assembly is mounted in a 25.4 mm outer diameter black anodized aluminum housing for protection and ease of mounting and has a 17.8 mm clear aperture. The wave plate fast axis marked for alignment reference. Polymer wave plates offer benefits over quartz wave plates such as better angular acceptance and less sensitivity to wavelength change. Polymer wave plates have excellent angular field of view. Retardation changes by less than 1% over a �12� incidence angle. The polymer material has very low birefringence that is nearly constant with wavelength..

US Laser Polarizing Prism Attenuator 1064nm
$425.00US Laser Polarizing Prism Attenuator
U. S. Laser Adjustable Attenuator, Model 1005-3-B-2 on carrier fitting US Laser optical benches. Carrier has sprocket-driven belt linkage to rotatable wave plate. Polarizing prism is adjustable through 360 degrees and can be locked via a clamping ring. Prism is about 12mm square in cross-section. Free opening of holder is 10mm diameter. The wave plate may be rotated independently of the prism. It has it�s own locking collar. Attenuation adjustment range has a ratio of approximately 100 to 1, with a less than 15% insertion loss.
Optics are in perfect condition as is the main rotating mount assembly. However the countershaft with the sprocket has been slightly bent and there are some teeth missing on the belt. The stainless steel lever for adjusting the initial orientation of the polarizing prism is missing. Axle and belt could be replaced very easily (axle is held in place with two �E� clips). Handle for polarizer simply threads in place and threads are not damaged. The drive mechanism has the advantage of allowing attenuation adjustment without having to open the laser enclosure. The external actuator knob and system connecting the carrier to the external actuator are not present.

US Laser Polarizing Prism Attenuator with Rotating Waveplate
$500.00US Laser Polarizing Prism Attenuator with Rotating Waveplate for 1064 nm
U. S. Laser Adjustable Attenuator, Model 1005-3-B-2 on carrier fitting US Laser optical benches. Carrier has sprocket-driven belt linkage to rotatable wave plate. Polarizing calcite prism is adjustable through 360 degrees and can be locked via a clamping ring. Prism is about 12mm square in cross-section. Free opening of holder is 10mm diameter. The wave plate may be rotated independently of the prism. It has it�s own locking collar.
All parts of the assembly are in flawless condition including the optics. Attenuator allows adjustment of laser intensity over a range of approximately 100:1 with a less than 15% insertion loss. The drive mechanism has the advantage of allowing attenuation adjustment without having to open the laser enclosure. The external actuator knob and system connecting the carrier to the external actuator are not present..

Laser Calcite Polarizing Prism
$199.00We are not sure of the manufacturer of this item � it has no maker�s markings anywhere.
We suspect Wollaston may be the manufacturer.This is a holder with a calcite prism installed. It splits an incident laser beam (shown in the photos with a small HeNe laser) into two beams perpendicularly polarized to each other. One beam appears to be much more divergent than the other, but this was not tested on an optical bench so no measurements were made. However, the beam that is �single� seems to process about the beam with the ghost images. I am not sure if the prism is a single oriented crystal of Calcite, or if it is actually a type of Wollaston prism. As can be seen in the third photo, the beam is split into two primary beams, one of which has the ghost reflections. I took additional photos with a polarizer alternately blocking the primary beam, and after a 90-degree rotation, the secondary (extraordinary) beam.
The cell mounting for the prism is 1 inch in diameter, not including the cap. The larger aperture on the smaller diameter side is about 5mm, that of the �cap� only about 3mm. There are two scribe marks on the cap which I would have thought indicated the permitted vibration directions of each beam, but they appear to be turned relative to the plane of polarization (perhaps the holder for the cell has the matching indications similarly offset).
The holders and prisms appear to be in perfect condition. The prism has some sort of anti-reflective coating but I am not sure what it is, or if it is optimized for a particular wavelength region. The prism appears to be approximately 7 or 8 mm square, but I was unable to measure this since access to the prism is precluded by the cap.
