  1. Value to be subtracted from the objective or illuminator working distance when the CMMR is used. For the CMMR4K Series, the minumum value is reported.
  2. To be ordered separately

Ordering information

Additional clamping mechanics are required to adequately support combination of CMMR with telecentric lenses and illuminators. CMHO series clamping mechanics can be used prior to verification of mechanical compatibility (see CMHO series mechanical drawings available online). CMHO is not compatible with the combination of the following two products: CMMR and TC13xxx.

CMMR4K models

CMMR4K are 45° first surface mirrors that produce a right-angled bend of the light path. CMMR4K  are available in two versions: -V and -L, respectively bending the light rays vertically (either upwards or downwards) or laterally (either to the left or the right). 

Additionally, the design of the CMMR4K models allows the user to flexibly adjust the distance between the mirror and the front end of TC4K/LTCL4K optics. Refer to the schematics for further details.

CMMR4K-V schematics

CMMR4K-V bends the light rays vertically.

CMMR4K-L schematics

CMMR4K-L bends the light rays laterally.
