Arducam offers C Mount adapters for Canon and Nikon lenses. Therefore, the C-CS adapter is required if you are using the DSLR lenses on a CS-Mount camera.

If you are using Arducam camera modules with CS-Mount, you can easily replace the CS-mount with an M12 mount by changing the lens holder.

Therefore, to adapter a CS-mount camera like this, you need an M12 to CS-Mount adapter. Here is an illustration of how that works.

Since CS-Mount is basically the same as C-Mount except for the flange focal distance, you can adapter a CS-Mount to C Mount by adding a 5mm C-CS adapter to a CS-Mount to use with C-Mount lenses.

NASA Langley has many fully instrumented laser laboratories in which a laser system can be engineered and evaluated. Typically, each laboratory has 2 or 3 optical tables.Each laboratory has a plethora of optics, and optical mounts.  These laboratories have a variety of equipment for laser operation and evaluation, including: power supplies, pulsed laser diode drivers, refrigerated baths, temperature controllers, power and energy meters, fast detectors, and fast digital oscilloscopes, Wavelengths are typically measured using monochromators under computer control or wavemeters, which can measure the wavelength to 6 figure accuracy. Beam quality and profiles are measured using a Si or InGaAs camera and interpreted with beam profiling software.

In some circumstances, you might want to convert the C/CS-Mount to an M12 mount. There are two ways to achieve that depending on the type of the CS Mount to be adapted.

TipThe flange focal distance is 17.526 millimeters (0.6900 in) for a C-Mount. CS-Mount has a flange focal distance of 12.526 millimeters (0.4931 in) but is otherwise the same as C-Mount, including the fact that lenses for many different formats are made for it.

Most of Arducam camera modules are compatible with 18mm and 20mm hole spacing, which match the majority of the lens holder’s. Here is a video showing how to do that.

The Raspberry Pi High Quality Camera, on the other hand, is not the same case. It’s lens holders – officially called the main housing – is not designed to be easily interchangeable.

The flange focal distance is 17.526 millimeters (0.6900 in) for a C-Mount. CS-Mount has a flange focal distance of 12.526 millimeters (0.4931 in) but is otherwise the same as C-Mount, including the fact that lenses for many different formats are made for it.

A C-Mount is a type of lens mount commonly found on CCTV cameras, machine vision cameras, and microscopes. C-mount lenses provide a male thread, which mates with a female thread on the camera. The thread is nominally 1 inch (25.4 mm) in diameter, with 32 threads per inch (0.794 mm pitch).

NASA Langley Research Center has a lengthy history of successfully developing laser materials and laser systems. We have worked with a wide variety of solid-state Lanthanide doped materials and transition metal doped materials, solid-state diode systems, and also have a capability in the demonstration and refinement of fiber laser systems. We have demonstrated narrow frequency systems, long and ultra fast short pulse systems, mode-locked systems, tunable injection seeded lasers, and many other technologies available in laser development. The following is an abbreviated list of laser technologies developed at Langley:

Therefore, if you find you cannot manage to focus a CS-Mount lens, check if you leave the 5mm C-CS adapter on the thread.
