Jelight 90-0020-01 Mercury Pen-Ray UV Lamp

formerly designated as legacy model 11SC-2, is a compact low-pressure mercury source providing primary 254 nm output across a 19.1 mm (0.75 in.) lighted length. Designed for restricted-access applications, its short double-bore quartz construction is well suited to compact analytical instruments, optical systems, photochemical setups, and OEM equipment. The lamp uses a standard Pen-Ray connector and is designed for use with the Jelight PS-1 power supply.

Applications

Compact Analytical Instrumentation

The short lighted section of the 90-0020-01 makes it useful in analytical equipment where available space or optical access is limited.

Photochemistry and UV Exposure

The 90-0020-01 provides localized 254 nm UV exposure for small reaction volumes, confined experimental systems, and other applications requiring concentrated shortwave UV illumination.

Optical and Reference Applications

Stable mercury emission makes the 90-0020-01 suitable for optical systems requiring a compact shortwave UV source for reference, measurement, or experimental work.

OEM and Restricted-Access Integration

Its 19.1 mm (0.75 in.) lighted length and single-ended double-bore design make the 90-0020-01 particularly useful for compact instruments, narrow openings, confined chambers, and custom OEM assemblies.

Features

• Short UV-emitting section supports restricted-access and space-constrained applications.
• Primary 254 nm mercury output supports analytical, optical, and photochemical work.
• Double-bore construction places electrical connections at one end for easier equipment integration.
• Compact geometry enables localized UV exposure within small instruments and experimental systems.
• Quartz construction supports transmission of shortwave mercury UV radiation.

FAQs

Is the 90-0020-01 intended for localized UV exposure?

Yes. Its short lighted length makes it particularly useful when UV radiation needs to be concentrated within a small reaction volume, optical path, instrument cavity, or other confined area.

What safety precautions are required when using the 90-0020-01?

Shortwave UV radiation can injure the eyes and skin, and this lamp can generate ozone. Operate the lamp only in appropriately engineered equipment using suitable UV shielding, eye and skin protection, ventilation, electrical safeguards, and ozone controls appropriate to the application.
