Stabilized Laser Reference for all IR-ranges


Stabilized Laser Reference for all IR-ranges

The Stabilized Laser Reference SLR-1555 incorporates a hydrogen cyanide absorption spectroscopy system, which yields very accurate frequency stabilization, ideal for calibration of our wavelength meters in the infrared wavelength regime.

Plug and Play Functionability

The SLR-1555 features extremely short warm-up period of < 1 min and narrow linewidth with high precision, optimized to function as a calibration source for most infrared capable Wavemeters.

The output power can be easily attenuated from max. to 0 output and thus be perfectly adjusted to fit the requirements of the mesurement setup.
