Wavelength Selectable HeNe Laser Features:

• Output at 633, 612, 604, 594 & 543nm
• Excellent Power, Beam Pointing & Thermal Stability

Thorlabs offers a line of Selectable Wavelength, Five-Color HeNe Laser Systems that are switchable between all of the main visible neon laser transitions (543nm, 594nm, 604nm, 612nm, & 633nm), a feature that makes it a versatile and economical research tool.

The HTPS and HTPS-EC HeNe Lasers incorporate a low loss plasma tube with one sealed Brewster Window and an external Littrow Prism. By adjusting the angle of the Littrow Prism with micrometer adjustments on the rear panel, the user can select among the visible neon laser transitions. A power supply is housed internally in the laser, making the unit completely self-contained. Choose the HTPS for 110V operation and the HTPS-EC for 220V operation.
