About This Product

■Product overview

The SR540 optical chopper is a device for pulsing a continuous light source. Can be pulsed in the frequency range of 4 Hz to 3.7 kHz. Two types of slot blades are included as standard: 5/6 hole and 25/30 hole, which can be used depending on the frequency. The chopping frequency can be controlled externally using an external voltage control input. You can output a synchronization signal to the outside from the external sink output to a lock-in amplifier, etc. The chopper head can be installed to suit various optical systems thanks to the base plate with rod fixing holes (screw type) and 2 inch pitch (50.8 mm) long holes.

■Features

・Chopping frequency 4Hz to 3.7kHz ・Low phase jitter ・Single and dual beam optical system compatible ・Sum frequency, difference frequency reference output ・Bottle clamp and rod mounting possible

■Applications

Pulsing continuous light specification

■Control input voltage

0 to 10 VDC 0 to 100% full scale Potentiometer does not function when voltage is input.
