Delay Pulse Generator
Manufacturer's part number :
New timing device designed to allow the PEM to work with pulsed light sources. The Delay Pulse Generator allows the user to trigger two other devices (up to 12 events per device) from the reference signal of the PEM. The PEM is a resonant device that cycles through polarisation states in 15-25 microseconds (for an I/FS50 the frequency is nominally 50 kHz, the period 20µs). For a given device, this frequency and period cannot change. A continuous light source will have its polarization modulated at the PEM frequency. However, a pulsed light source will require timing compatibility such as that provided by the Delay Pulse Generator to synchronise with a PEM in a polarisation application set up.
