Jelight 90-0019-01 Mercury Pen-Ray UV Lamp

formerly designated as legacy model 11SC-1L, is a compact longwave mercury light source providing principal 365 nm UVA output across a 57.2 mm (2.25 in.) lighted length. Its blue filter sheath absorbs visible light, making the lamp well suited for fluorescence, photochemical, analytical, and optical applications requiring a compact longwave UV source. The 90-0019-01 uses a standard Pen-Ray connector and is designed for use with the Jelight PS-1 power supply.

Applications

Fluorescence and UV Inspection

The 90-0019-01 provides longwave UVA output suited to excitation of fluorescent materials and other UV-responsive samples.

Photochemistry and Materials Research

Its compact 351/365 nm output makes the 90-0019-01 useful for UVA-driven photochemical studies and controlled exposure of photosensitive materials.

Analytical and Optical Instrumentation

The stable longwave mercury output supports analytical and optical systems requiring a compact UVA excitation or reference source.

OEM and Laboratory Equipment Integration

The compact, single-ended Pen-Ray design allows the 90-0019-01 to be incorporated into instruments, optical assemblies, experimental systems, and OEM equipment where space is limited.

Features

• Longwave UVA output supports fluorescence, photochemical, analytical, and optical applications.
• Blue filter sheath reduces unwanted visible light for cleaner longwave UV illumination.
• Compact double-bore construction places electrical connections at one end for easier equipment integration.
• Stable low-pressure mercury operation supports repeatable laboratory and instrumentation applications.
• Relatively low thermal output helps limit unwanted heating of samples and system components.

FAQs

Why does the 90-0019-01 have a blue filter sheath?

The blue filter sheath absorbs unwanted visible light while allowing the lamp to provide its characteristic longwave UV output. This makes the 90-0019-01 particularly useful for applications where fluorescence or other UVA-driven responses must be observed with reduced visible-light interference.

What safety precautions are required when using the 90-0019-01?

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