Reflecting Microscope Objective Near IR to Near UV
This is a Nicolet Instruments Corp Reflecting Microscope Objective, Near IR to Near UV.
This is another very unusual reflecting microscope objective of the Cassegrain type. Mirrors are used for all of the imaging elements – there are no refractive components. As a consequence the objective is largely free of chromatic aberrations over a large spectral range. The objective is suitable for work from the near UV well into the IR region. It appears that the reflecting elements are silver (aluminum coating?). I could not see any blemishes in the coatings.
The aperture of the objective is very small (only about 5mm diameter) so the secondary mirror is minute. The initial magnification must be quite high – probably in the range of 50x to 75x. Unfortunately there is no nomenclature anywhere on the lens. It is probably intended for use on an IR imaging microscope of some sort. It does have an RMS thread adapter with a locking collar for orienting the objective on the adapter.
Thread mount – RMS thread on centering adapter
Overall height to thread shoulder – 82mm
Diameter of system – 70mm
Diameter of front aperture – 5mm
The lens also has a side port that is aligned with a slot in the base of the objective. There appears to be some sort of right-angle mirror in the slot that occludes one half of the imaging elements. The port is either for a vertical illuminator or for some sort of detector. There is a thread in the anodized hub visible through the bore in the chrome shroud.
The objective appears to be in perfect condition. Could only see one half of the mirror system, but it looked unblemished.

Reflecting Microscope Objective (Near IR to Near
This is a special Cassegrain type reflecting microscope objective. It consists of a pair of mirrors, a larger concave primary mirror and a smaller convex secondary mirror. There are no refractive imaging elements. There is an aperture in the large diameter chrome-plated shroud underneath which is a blanked slide way. The aperture is blocked but it looks like one could turn the center hub to align a second aperture for access to the interior. Possibly this is for some sort of vertical illuminator accessory, or an external detector system..
The mirrors appear to have a conventional aluminum coating – they are not gold-coated. Condition of both mirrors appears to be perfect. They are relatively small so I would infer that the initial magnification is in the range of 30x to 50x. There is no nomenclature anywhere in the system nor do I know who manufactured the piece. It is most likely from an infrared microscope, but it would be possible to use this in the near UV range.
Mounting thread – 14.75mm (inside thread diameter)
Diameter of system – 70mm
Height of system – 51mm
Diameter of front aperture – 7.5mm
The mounting thread is also unusual – it is female and somewhat smaller than an RMS thread. It is possible that there is a missing intermediate adapter. The objective is in superb condition (the ‘mottled’ appearance at the top of the chrome in the first photograph is actually a reflection – the plating is perfect).

Fixed Lens Mount for 1 inch Components with set screws
These Thorlabs 1 inch fixed lens mounts have a nylon-tipped set screw for securing the component. They are furnished with a custom base that has a radius on the back side with a matching slot. It appears they were to be mounted against a similar reference surface where they could be turned in an azimuth direction through several degrees. The upper side of the base has a reference ledge for orienting the lens holder..
These are very well-made and in near-new condition. Listing includes both the Thorlabs lens holder and the special base. A typical 0.25 inch thick mirror placed in the holder would be located very close to the axis of rotation.
