Specialised Lamps

Astronomical spectrographs are used for a variety of high-precision measurements, ranging from the discovery of low-mass exoplanets to the possible variation of fundamental constants, such as the fine structure constant or the proton-electron mass ratio. These works require excellent wavelength...

Reliable, element-specific light source for laser calibration and high-resolution spectroscopy. The Optogalvanic Lamp produces a detectable voltage change when exposed to resonant laser light, making it ideal for precise wavelength tuning, atomic transition studies, and plasma diagnostics.  ### Special order...
