Jelight 90-0012-01 Mercury Pen-Ray UV Lamp

is a compact, double-bore quartz light source producing primarily 254 nm UV-C radiation, with additional 185 nm emission capable of generating ozone. Featuring a 53.8 mm (2.12 in) lighted length and phenolic handle, it is designed for analytical, photochemical, and optical applications using the Jelight PS-1 power supply.

Applications

Photochemistry

The 90-0012-01 provides shortwave ultraviolet radiation for photochemical reactions, UV-driven research, and laboratory irradiation experiments. Its compact dimensions allow integration into specialized photochemical equipment and experimental assemblies.

Analytical Instrumentation

Provides characteristic mercury emission for analytical instruments, photometric systems, and UV detector applications. Its compact quartz construction supports installation within laboratory and OEM optical assemblies.

Wavelength Calibration and Optical Reference

Characteristic mercury emission lines serve as reference wavelengths for spectroscopic calibration, optical measurements, and detector evaluation. The lamp supports applications requiring a compact mercury spectral reference source.

Ozone Generation and Monitoring

In addition to its primary 254 nm output, the 90-0012-01 emits 185 nm ultraviolet radiation capable of generating ozone in oxygen-containing environments. This makes it suitable for compatible ozone-generation, monitoring, and research systems equipped with appropriate ventilation and safety controls.

Frequently Asked Questions

How does the 90-0012-01 differ from the 90-0003-01?

The primary difference is the handle material. The 90-0012-01 features a phenolic handle, while the 90-0003-01 uses an aluminum handle. Both models share the same primary wavelength, principal dimensions, connector configuration, and recommended power supply.

Which power supply is required for the 90-0012-01?

The Jelight PS-1 power supply is recommended for this lamp. It is available in 115 V (99-0055-01) and 230 V (99-0055-02) versions and is sold separately. Select the appropriate version for the available electrical supply.

Does the 90-0012-01 produce ozone?

Yes. The lamp emits 185 nm radiation that can generate ozone when it interacts with oxygen in the surrounding environment. Appropriate ventilation and ozone-exposure controls are necessary when operating the lamp.

What safety precautions are required when using the 90-0012-01?

Avoid direct eye and skin exposure to UV-C radiation by using appropriate UV-protective eyewear, shielding, and protective clothing. Provide adequate ventilation to control ozone exposure, avoid touching the lamp while hot, and disconnect the power supply before handling or servicing the lamp.
