P809ST - Optogalvanic (See Through Hollow Cathode Lamp HCL) - Calcium


Optogalvanic Lamps or See Through Hollow Cathode Lamps (HCL) are designed to act as a frequency stable reference for high intensity tuneable monochromatic light sources, particularly lasers.

Most of the cathode materials used in standard hollow cathode lamps may be used in the “see-through” design. We can also offer a range of fill gases, such as: Neon, Argon, Xenon and Krypton.
