Two Flat Head Hex Screws are used for Cube Cover Removal and Filter Replacement
The CM1-DCH dichroic filter cube holds a rectangular dichroic mirror or other rectangular optic up to 36 mm wide, 26 mm tall, and 3 mm thick using the integrated filter clamp. Two flat head hex screws on the base of the cube can be unscrewed with a 1.5 mm hex key to detach the base from the cube housing, allowing access to the mirror clamp (See the photo below right).
Emission and excitation filters can also be mounted into short lens tubes and attached to the SM1-threaded ports for a full fluorescence imaging filter setup (see the Application tab for more information). CM1-DCH cubes have four 4-40-threaded holes on each face for 30 mm cage system integration and are post mountable via an 8-32 (M4) tap. The cubes can also be connected sequentially using the CM1-CC cage cube connector sold below.
Please note: The filter holder base features a modified FFM1 filter holder mount. Our catalog FFM1 is not compatible with the CM1-DCH. Additional CM1-DCH bases may be ordered as a special by contacting tech support.
If any of our microscopy filters is ordered at the same time as the CM1-DCH, Thorlabs will premount the filter at no additional charge. In order to take advantage of this option, please contact Technical Support prior to ordering.
