ES-12 Semiconductor Laser

A rugged pin-mounted laser with focussing and an optical stablizing Power Supply built into the case. Radiates at 670 nm in the deep red. Less expensive and much more durable than a glass laser.

 ES-10 Helium Neon Laser

The basic red (632 nm) laser with excellent coherence and an internal Power Supply.

 ES-18 Small Mercury Arc

A small mercury arc supplying monochromatic radiation in the ultra violet through the yellow region of the spectrum. A perfect source for the Photoelectric Effect and the Student Spectroscope.

 ES-20 Spectral Arc Power Supplies & Spectral Arc Lamps

Power for a range of spectral arc lamps. Available Spectral Arcs

 ES-16 High Intensity Light Source

A compact and very bright source for all optical bench and imaging uses.
