Ultraviolet (325-nm) He-Cd Laser
Helium cadmium lasers are ideal laboratory instruments. They incorporate dual Brewster windows to ensure optimum polarization, Features include:
- Linear polarization with >500:1 extinction ration
- Unsurpassed mode quality with M2 < 1.10 on TEMoo versions(Linear Polarization)
- Excellent mode quality with M2 < 1.2 on TEMoo versions(Random Polarization)

Dual Wavelength (325 & 442nm) He-Cd Laser
dual-wavelength HeCd lasers are available in two configurations. Polarized systems use an external resonator cavity that provides exceptional beam quality with a 500:1 extinction ratio. Unpolarized laser systems use an internal mirror configuration that requires no optics cleaning for the life of the system.
