Optogalvanic Lamps

Optogalvanic Laser Calibration See Through Hollow Cathode Lamps provide a sensitive optogalvanic effect when used with laser beam directed through the cathode discharge by measuring a change in the discharge current caused by optical excitation. The see through cathode design also acts as a frequency stable reference, particularly used with lasers in laser calibration.

Using a see-through cathode of high purity material, the laser does not strike the cathode surface so there is no photoelectric noise. See through hollow cathode lamps have been successfully used in many applications such as Optogalvanic Spectroscopy, Astrophysics and Observatory.

Most of the single element hollow cathode lamp materials may be used in the “see-through” design. We offer standard gas filler Neon or your choice of other gases such as Argon and Xenon.
