6033 Spectral Calibration Lamp

The 6033 Spectral Calibration Lamp produces narrow, intense lines from the excitation of Xenon gas. This lamp operates at 3 to 9 mA and is rated for 250 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).

AC Power Supplies Available

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.

Three Filter Types Offered

Spectral output of the 6035 Hg(Ar) lamp with different filters used

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.

6041 Short Wave Filter: Blocks visible wavelengths
6042 Long Wavelength Conversion Filter: Attenuates the 253.7 nm Hg emission line and allows transmission from 300-400 nm
6057 Glass Safety Filter: Protects the user from the lamp's intense UV spectral lines, completely blocks the 253.7 nm Hg line and attenuates the 312.6 nm line

Fiber Optic Accessory

The 6058NS Fiber Optic Accessory holds the face of an SMA terminated fiber close to the lamp to collect a portion of the light output for spectral calibration purposes. The optical post and holder are not included.

Post Mounted Lamp Holder

The 63670 Holder is suitable for mounting the pencil style calibration lamp for open air configurations. The 2.0 inch optical post SP-2 in the picture to the right is included.

Monochromator Mount for Spectral Calibration

The model 78819 spectral calibration lamp mount holds a calibration lamp securely at the input slit of an Oriel Monochromator or Spectrograph. Compatible with Oriel's 1.5 inch size flange series, the 78819 provides close coupling for excellent throughput with minimum light leakage.

Three Aperture Shields Available

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:

6038 Pinhole Shield: 0.040 inch (1 mm) diameter
6039Small Aperture Shield: 0.313 x 0.375 inches
6040 Large Aperture Shield: 0.188 x 1.50 inches
