Comparison lamps

Several lamps are available in the INT A&G unit for wavelength calibration. Two lamps are allowed to be simultaneously used, and they are by default Copper-Argon in position 1 and Copper-Neon in position 2. Users wanting a different one should specify their requirements in advance so that the lamp is installed by the duty technician in place of the standard ones.
