C-mount block


This C-mount thread optical block is for installing a dichroic mirror for use at a 45 degree angle of incidence. You can use typical dichroic mirrors that are commercially available for use with microscopes.


Type No. Effective beam size Compatible dichroic mirror size Weight
A11214 φ20 mm 25 mm to 26 mm (W) × 35 mm to 38 mm (H)
Thickness: 0.9 mm to 1.1 mm (1 mm recommended)
Approx.84 g

* Supplied: Hex wrench S2.0

Connection example: Fiber-optic dual / triple wavelength detection

The dichroic mirror assembled in the block reflects light at wavelengths shorter than a specific wavelength and transmits longer wavelength light. Furthermore, only light at a specific wavelength passes through the optical filter and is then detected by the PMT module.

Dual wavelength detection

Triple wavelength detection
