Short Arc Mercury/Xenon (Hg/Xe) Deep UV Point Source Optics
Product Summary

The Ushio UXM-Q256BY is a short-arc mercury/xenon (Hg/Xe) deep ultraviolet lamp used in optical systems that depend on high-intensity, compact-arc output for efficient collection, focusing, and UV energy delivery. Short-arc lamps are selected for how their arc couples into the reflector and condenser geometry — replacement accuracy protects optical alignment and UV dose stability.

Ushio describes its Deep UV Hg/Xe lamp family as high-intensity point light source mercury vapor-filled lamps based on xenon lamps, with characteristic UV radiation roughly in the 230–320 nm wavelength range for short-wavelength photochemical reactions, UV curing, and lithography-related uses.

Deep UV Hg/Xe Short-Arc Lamps: Why Optical Coupling and UV Throughput Decide Real-World Performance
A Short-Arc Lamp Is a Geometry Match

In short-arc systems, the arc is effectively the optical “reference point.” Reflectors and condensers are designed around it. If a replacement lamp changes arc location or how the emitting region behaves, you can see real changes at the target plane: lower coupling efficiency, shifted focal spot, or uneven irradiance. That’s why deep UV systems typically specify the exact lamp model — the lamp and the optical train are designed as a unit.

Deep UV Output Is Defined by Wavelength and Throughput

Ushio characterizes its Deep UV Hg/Xe lamp family as high-intensity point light source mercury vapor-filled lamps based on xenon lamps, with UV radiation roughly in the 230–320 nm wavelength range for applications including photochemical reactions, UV curing, and lithography-related processes. Deep UV performance is often limited by the optical path (window haze, filter condition, reflector aging, deposits) before it is limited by lamp wattage.

Stability: Don’t Troubleshoot Only the Lamp

If dose or intensity is unstable, the root cause is frequently in the full chain: power regulation, igniter behavior (if applicable), lamphouse alignment, and sensor calibration. A new lamp can temporarily hide those issues without solving them. In controlled UV processes, stability is a system-level characteristic.

Safety: UV + Mercury Requires Discipline

Deep UV can injure eyes and skin in seconds. Mercury-containing lamps require compliant handling and disposal. Use only in properly interlocked housings with appropriate shielding and follow your facility’s EHS requirements for replacement procedures.

SOSCleanroom Practical Tip
If “UV is low,” confirm the exact lamp model first — then inspect the UV path. A thin film on a window or filter can cut deep UV throughput dramatically, even when the lamp is healthy.
