Have a look at our lineup of professional-grade diode, WBS, and helium neon (HeNe) lasers. Diode lasers are great for optical voice transmission and general purpose optical beam experiments. Our helium neon lasers have the same great features as our diode lasers and are available in modulated and unmodulated models with power ranging from 0.5 to 3.5 milliwatts. The WBS laser is the ultimate educational laser because of its dual analog and digital input design and wide electrical modulation bandwidth.
