Compact green laser modules combining Nd:YVO4 and KTP crystals pumped by an 808 nm diode. They drop into a standard 5.6 mm laser diode pin layout but give much lower beam divergence than a semiconductor diode, for CW use only.
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.
Self-contained collimated laser diode modules in six wavelengths from 405 nm to 1550 nm. Each housing holds a Fabry-Perot diode, collimating lens, power controller and a built-in shutter, with internal SM1 threads so they mount straight into a lens tube system.
