60mm F/1.0 LWIR Manual Focus Lens For 17um Sensor

What are the reasons for the lens control board or module not connecting to the computer?

There are several possible causes that can be checked one by one:

1. Try a different USB port, as the current one may not be compatible with the data cable;

2. Use a different data cable that is compatible with both the computer and the lens control board or module;

3. Check the wiring of the module or control board to ensure that it is securely connected;

4. If none of the above steps work, it may be a hardware issue and the module or control board may need to be replaced.

FAQ:

What Are DLC And AR Coating?

Diamond-like carbon (DLC) membrane is an amorphous carbon membrane. The membrane contains a certain number of sp3 bonds, giving it a series of excellent properties close to diamond. It has the advantages of low deposition temperature and large area deposition.

Among various hard membranes, DLC membrane can be positioned as a membrane material with high hardness and excellent wear resistance and low coefficient of friction.

AR (Anti-Reflection) membrane cannot change the absorption rate of the lens itself. It can only increase the transmittance by reducing the reflectance on both sides of the lens, which is the so-called "reflection and antireflection".

Light is an electromagnetic wave. By matching the refractive index and thickness of the AR membrane, the light produces multi-beam interference in the AR membrane-destructive interference on the upper surface and constructive interference on the lower surface.
