Ushio UXM502MD 500W Short-Arc Mercury/Xenon Deep UV Lamp
Deep UV • Point light source behavior • Specialty analytical / industrial applications
Deep UV (Hg/Xe) Short-arc 500W class

The Ushio UXM502MD is a short-arc mercury/xenon (Hg/Xe) deep ultraviolet lamp used where a compact, high-intensity source is required and optical systems depend on point-source-like behavior for collection and control.

Ushio’s Deep UV lamp family is described as mercury vapor-filled lamps based on xenon lamps, with radiation characteristics in the middle UV region (roughly 230–320 nm) for photochemical reactions, UV curing, and lithography-related uses. (System requirements vary by application and optical design.)

Key Identifiers

Safety & Use Note (Deep UV)
Deep UV sources can present eye/skin hazards and, depending on lamp construction, may involve regulated materials. Use only in properly interlocked housings with appropriate shielding, PPE, and disposal procedures required by your facility and local regulations.
Deep UV Hg/Xe Short-Arc Lamps: Why “Point-Source Behavior” Matters More Than Raw Watts
The Technical Vault By SOSCleanroom
Deep UV Short-arc Hg/Xe Optical coupling

In deep UV work, lamp selection is rarely about “brightness.” It’s about how efficiently your optical system can collect, shape, and deliver usable UV energy to the target plane. That’s where short-arc lamps win: the emitting region behaves closer to a point source than broader, diffuse emitters, which simplifies collection and improves uniformity after optical conditioning.

Ushio describes its Deep UV lamps as mercury vapor-filled lamps based on xenon lamps, with characteristic radiation in the middle UV region (roughly 230–320 nm). That combination supports applications where short-wavelength UV energy drives chemistry or surface effects—photochemical reactions, UV curing, and lithography-related processes—while still benefiting from optical controllability associated with short-arc designs.

What to validate before ordering a replacement

1) Mechanical fit: base type, envelope geometry, insertion depth, and alignment features must match the lamphouse.

2) Electrical operating window: power supply compatibility and operating setpoints must match the lamp’s required mode.

3) Optical expectations: collection angle, irradiance stability, and wavelength relevance should be validated against your process or instrument requirements.
