WebThe New Focus Model 3501 Optical Chopper System is designed to interrupt light paths in optical experiments at frequencies from 4 Hz to 6.4 kHz. Both single and dual beam experiments can be performed across a broad range of chopping frequencies. The chopper has a crystal controlled frequency synthesizer that serves as an internal reference ... WebThe Model SR540 Optical Chopper is used to square-wave modulate the intensity of optical signals. The unit can chop light sources at rates from 4 Hz to 3.7 kHz. Versatile, low jitter reference outputs provide the synchronizing signals required for several operating modes: single or dual beam; sum & difference

WebJun 10, 2013 · The classification of choppers is done based on the frequency of operation as – variable frequency rotating disc chopper, fixed frequency tuning fork chopper and optical shutters. Applications WebOptical Choppers. Our optical choppers introduce a periodic interruption of the light path - useful for small optical signal detection schemes. The chopping frequency is phase-locked to its own internal frequency synthesizer, providing rock-solid stability and flexibility. Showing 3 products in 2 families. coffee bean art images
