3.3 LENS SETUP
The C-Mount screw is a socket to hold applicable lenses. In some cases, an adaptor-coil is needed to
ensure the correct flange back. This is not exceptional, but a current way to counteract imprecise
manufacturing.
3.2.1. Choosing a lens
Independent of the focal length, there is an important characteristic of C-Mount lenses which should
be considered when choosing a lens. Because of the existence of different sensor dimensions (1/3
inch, ½ inch and2/3 inch) and senor quantities (3x ½ inch or 1x 2/3 inch etc.) and the fact that the
Cunima MCU[2] does contains single CMOS sensor with Beyern-pattern, please only use lenses
which are engineered for that indented purpose (
CUNIMA: 2/3 inch single CMOS sensor ).
3.2.2. C-Mount thread
1. Please remove the rubber protection of the Cunima MCU[2]. You can see the C-Mount thread
now. Please note that behind the thread is the glass protection of the sensor. This glass
should not be damaged or it may constrain the image quality.
2. Remove the lens and check for possible damages. Please do never mount a damaged lens on
the Cunima MCU[2]. Further damages of the camera because of optical small parts like glass
splinters could occur.
3. Screw the lens into the C-Mount.
4. If the flange back of the lens is not right, you may use the backfocus (see chapter 3.4)
adjustment feature of the CUNIMA MCU [2].
Whenever there is no lens screwed on the C-Mount, please make sure that a protection
rubber protects the cameras glass filters to avoid any damages!
