CE compliant helium neon lasers at 632.8 nm with output powers from 0.8 mW to 22.5 mW. Their beam quality and gas discharge behaviour make them the standard source for undergraduate optics teaching, interferometry, alignment and polarisation experiments.
Coherent semiconductor power sensors measure the average power of continuous wave and modulated lasers at very low powers with fast response. Silicon and ultraviolet enhanced silicon models cover the ultraviolet to near infrared, while germanium models extend further into the infrared.
A helium neon laser at 632.992 nm that can be locked in either frequency stabilised or intensity stabilised mode. It is used as a wavelength reference for spectroscopy, interferometry and wavemeter calibration, reaching lock in under fifteen minutes.
