Jelight 90-0071-03 Cadmium Pen-Ray UV Lamp

is a compact spectral light source providing prominent cadmium emission lines near 229 nm and 326 nm for UV absorption measurements, air-pollution monitoring, SO₂ analysis, wavelength calibration, spectroscopy, and analytical instrumentation. Its thermally isolated lamp construction supports stable operation, while 203 mm (8 in.) stripped radial leads support integration into compatible instruments and OEM systems. The 90-0071-03 is designed for use with the Jelight PS-9 power supply.

Applications

UV Absorption and Detection

The 90-0071-03 provides defined cadmium spectral lines for UV absorption cells, detectors, and analytical measurement systems requiring a compact ultraviolet reference source.

Air-Pollution Monitoring and SO₂ Analysis

Cadmium Pen-Ray lamps are well suited for environmental and air-pollution monitoring equipment, including compatible SO₂ analyzers and other instruments that use defined UV wavelengths for optical measurement.

Wavelength Calibration and Spectroscopy

The characteristic cadmium spectrum provides multiple defined emission lines that can serve as references for wavelength calibration, UV spectroscopy, optical testing, and instrument development.

OEM and Analytical Instrument Integration

The 90-0071-03 uses 203 mm (8 in.) stripped radial leads that exit around the perimeter of the lamp base, supporting integration into analytical instruments and OEM systems designed around a radial electrical connection.

FAQs

What are radial leads?

Radial leads exit around the side or perimeter of the lamp base rather than directly through its end. The 90-0071-03 is supplied with 203 mm (8 in.) stripped radial leads for integration into compatible equipment.

Does the 90-0071-03 produce ozone?

Yes. The cadmium spectrum includes shortwave UV emission capable of generating ozone in oxygen-containing environments. Appropriate ventilation and application-specific ozone controls should be considered during operation.

What safety precautions are required when using the 90-0071-03?

Avoid direct exposure of the eyes and skin to ultraviolet radiation. Use appropriate UV-blocking eyewear, shielding, protective clothing, and ventilation suitable for the installation and application.
