We have Hydrogen (H2), Helium (He) and Mercury (Hg) lamps for light source for Refractometer, Wavelength calibration and analytical instruments. Our Hydrogen and Helium lamps are used for astronomical spectrophotometers in US observatory as wavelength calibration, and we have high reputation from them. If you have a request for any other lamps, please contact us.
