This item appears to be some sort of gold-coated CO2 laser beam direction mirror. It is marked as having a type �PO� coating, which I assume is a variant of the MaxR coating optimized for 10.6 micron wavelength (angle of incidence is not stated). Please see the first photo for the information label attached to the case…

There is a part number on the mirror � 7R028072-13 B. It is manufactured by Laser Power Optics and is secured in a protective container. The mirror appears to be new, and I could see no flaws in the surface. The shape is rather unusual � about 2.75 inches in diameter, but with one corner squared. There are three bolt positions..

Laser Beam-Combining Assembly with Camera Port…

This device appears to be a laser beam combining port so a camera system can image the workpiece on the same optical axis as the laser. This would be important for initial workpiece setup. There is no manufacturer�s mark anywhere, but the device is very nicely constructed. The camera port is completely open, with a smooth bore of 50mm aperture. On the beam delivery side, there is a focusing optic of 40mm diameter. This lens can be focused through a range of about 12mm via a small micrometer spindle.

The combining element appears to be some sort of dichroic filter � as expected, it remains stationary as the lens is focused. On the input side of the module are two components. The first appears to be a Schott Glass BG 38 blue glass filter. Mounted with that filter in the same bore is a lens of 24mm diameter. The inside diameter of the input port is 49mm, with a step down to 35mm after a depth of 6mm. There are three set screws placed equidistant in the 49mm portion of the bore.

Overall length of the assembly is 220mm with the lens fully extended. On the distal end of the objective is a thin slot that appears may have held a dark slide � presently it is empty. First photo shows the device from the side, camera port facing downwards. The second photo shows the camera port with the dichroic inside. The last photo shows the beam �input� port. The device appears to be in perfect condition with the exception of a trace of haze at the margin of one surface of the blue filter � barely visible at the edge. The objective, the smaller relay lens, and the dichroic beam-splitter are all flawless..

This item is one of several interchangeable pinholes available for the Spectra Physics Type 332 Spatial Filter. This one is marked simply �APERTURE-3, 6.8 microns�. It threads into the collimator side of the spatial filter.

PLEASE NOTE The pinhole is only available with the purchase of a Type 332 spatial filter � it will not be sold individually. The pinhole is in perfect condition, although a bit of the foil label with the nomenclature is missing (see second photo).

This is a Model 336 Multi-Wavelength Collimator manufactured by Spectra-Physics. It features a three-element construction. The focal length is 200mm, and the aperture of the objective is 50mm. It is highly corrected for the wavelength range of 450 to 650nm, and is optimized at 587.5nm. The mounting tube has a fine helical sleeve focusing. There is no diverging lens at the other end of the tube � this is just the collimating objective. This may be used with the type 332 Spatial Filter mounting.

The lens is coated, and the surfaces are free of blemishes. There is no delamination. Thread diameter of the helical base mount is 1� Nomenclature has mostly been worn away, although some of it is barely legible with a magnifying glass. We had another lens with which we could compare this objective in order to confirm type and focal length.

This is a Spectra Physics collimation objective with focusing mount. The product number is 331. The objective has a focal length of 182mm, and a 52mm clear aperture. The focusing mount uses an internal helical thread to move the objective without rotation. The mount does have numerous scratches in the finish, but the objective is in flawless condition. Focusing motion is very smooth. Some of the objectives are missing the black plastic finish ring (see photos). The lens is nominally corrected for 632,8nm (HeNe laser).

This collimator may be used with the Spectra Physics Type 332 Spatial Filter assembly which consists of three components � the filter mount, the objective lens, and a pinhole. They are available separately..
