The 6035 Spectral Calibration Lamp produces narrow, intense lines from the excitation of Argon gas and Mercury vapor. The 6035 Hg(Ar) Lamp is insensitive to temperature. It requires a two-minute warm-up for the mercury vapor to dominate the discharge, then 30 minutes for complete stabilization. The average intensity is remarkably constant and reproducible after the thermal conditions stabilize. This lamp operates at 18 to 23 mA and is rated for 5000 hours of life. It is used for wavelength calibration of spectroscopic instruments such as monochromators, spectrographs, and spectral radiometers. We call this a pencil lamp because of its size and shape. It is made of double bore quartz tubing with two electrodes at one end sealed into a phenolic handle. A 1 foot (305 mm) long cord with male connector is attached to the end of the handle for connection to the AC power supply (not included).
We offer AC power supplies specifically designed for pencil style calibration lamps. These power supplies are required for proper operation of the calibration lamps. AC power supplies have the benefit of being CE compliant and prolonging lamp life, as they operate lamps with small variations in output intensity. There are two models for each lamp type based on geographic location and AC power requirements of that region.
When only certain portions of the lamp's output are required, three different filters are offered to block out the undesired spectral lines. Like the aperture shields, these filters simply slide over the lamp.

When the radiation area of the lamp must be limited, Oriel offers three aperture. These aperture shields simply slide over the pencil calibration lamp and limit the lamp's output with the following aperture dimensions:
