Boston Micromachines, a provider of MEMS-based deformable mirror products and adaptive optics systems, has introduced the Reflective Optical Chopper (ROC).
Designed to out-perform the traditional optical chopper, the ROC offers greater frequency range and a faster chopping speed without the need to alter the beam size.
Unlike traditional solutions which require the use of separate chopper wheels at different ranges of frequencies, the ROC can function continuously from sub-Hertz speeds up to 100kHz.
Even more, the versatile optical chopper does not require reduction of the size of the beam at higher speeds. As an added feature, scientists can chop the beam with an arbitrary pattern simply by providing an input signal.
