Helium-Neon Lasers, Continuous Wave Lasers

Continuous Wave and Helium-Neon Lasers are ideal for lab work or classroom demonstrations.

  • Hard-Seal Tubes
  • Impact-Resistant Acrylic Casing
  • Positive-Grip Rubber Feet
  • Power Adapter Provided
  • Full-Color Instruction Manual Provided
The lasers are contained in blue, impact-resistant acrylic housing with positive-grip rubber feet. The output end incorporates a manual beam-blocking safety shutter and has a threaded mount for standard beam-shaping accessories. The rear panel carries the power switch and jack that connects to the provided power adapter (115VAC). A standard 1/4-20 threaded hole in the base accepts a stand rod for optical bench or tripod mounting. The lasers emit red light with a wavelength of 632.8 nm in the TEM00 mode.

Continuous Wave (CW) lasers emit a continuous beam of light with only small output power variations after warming up. Modulated Lasers have additional jacks (3.5 mm audio) for a varying signal of 600Hz—20kHz to be input for modulating the output beam intensity, which can be used to measure the speed of light and for optical signal transmission experiments.

Certifications: UL approved.

Ordering information: This laser includes a full-color instruction manual.
