RS20B 20mm Optical Shutter

The RS20B is available by special order only, and may be subject to minimum order quantities. Please contact us for additional information.

Part Number: RS20B Category:


The Uniblitz RS20B is a 20mm-rectangular-aperture bi-stable optical shutter that contains all drive components within the shutter housing. Control only requires a supply voltage (5-12 VDC) and open/close pulses (TTL). The RS20B’s simple design provides maximum clearance around the aperture, and a machined flat surface makes for its easy integration into virtually any system. The RS20B’s flexibility, as well as the its carbon-impregnated PET shutter blade (“C” blade), make it suitable in applications such as non-uniformity correction (NUC), spectrometry, and high speed digital imaging systems.

Additionally, the RS20B can be utilized as a development platform with scalability to custom sizes and other specifications.
