Product Description
UV-capable xenon short-arc lamp with fused silica windowing and a compact arc for stable optical coupling.
 
Overview

The Ushio UXL-S75MA is a 75W xenon short-arc lamp built for UV-oriented optical systems that require a tight, high-luminance arc and repeatable output stability. It is listed within the UXL family as “Xenon Short Arc for UV” and uses a fused silica window to support deep-UV transmission, with a stated spectral range from 185 nm to 2000 nm. SKU: UXL-S75MA (5000876).

  • Window Material: Fused Silica
  • Spectral Distribution: 185 nm (short) to 2000 nm (long)
  • Stability (Drift): typ. ±0.5%/hour
  • Stability (Fluctuation): max 1% (p-p)
  • Average Life: 2000 hours
  • Orientation: Vertical ±15° or Horizontal ±15°
  • Cooling: Convection cooling

Typical Applications
  • UV-capable spectroscopy and optical measurement systems
  • Scientific instrumentation where stability (drift/fluctuation) impacts repeatability
  • Inspection platforms and specialty optical tools using compact xenon short-arc sources
Compare & Contrast (How to Substitute Safely)
For xenon short-arc lamps, “same wattage” is not enough. If you compare alternates, match arc length (1.3 mm), the stated spectral window (185–2000 nm), and the system’s allowable orientation tolerance (±15°). Also confirm the trigger voltage requirement (15 kV) is supported by your power supply/igniter.
Handling Tip
Xenon short-arc lamps are high-pressure devices and require an igniter. Avoid impact and do not service the lamp housing during operation. Follow OEM cool-down and shielding procedures, and ensure your power supply is rated for the specified trigger voltage.
Industry Update (Ushio & ENI Continuity)
Ushio has an agreement to acquire ams OSRAM’s Entertainment & Industry Lamps (ENI) business, with closing expected by the end of March 2026. During transitions, customers may see changes to branding, labeling, or packaging across some legacy lamp lines. SOSCleanroom will continue to supply and support specialty lamps and can help validate continuity by part number and critical specs.

Science: Why “Short Arc” + Fused Silica Matters

Xenon short-arc lamps generate light from an electrical arc between electrodes inside a xenon-filled envelope. A short arc length concentrates energy into a compact source, improving optical collection efficiency and enabling tighter focusing than longer-arc geometries.

For UV-oriented systems, window material is a gating factor. The UXL-S75MA specifies fused silica, which is commonly used to support transmission deeper into the UV compared with standard glass. The stated spectral window here is 185–2000 nm. Stability specs (drift/fluctuation) are included because output stability directly affects measurement repeatability in analytical optics.

Safety & Handling (Ignition + High Voltage)
This lamp requires an igniter and is specified with a 15 kV trigger voltage. De-energize and lock out the system before service, allow full cool-down, and follow OEM shielding/interlock procedures. Confirm your power supply/igniter ratings match the lamp requirements.
Industry Update (Ushio + ams OSRAM ENI)
Ushio has an agreement to acquire ams OSRAM’s Entertainment & Industry Lamps (ENI) business, with closing expected by the end of March 2026. Customers may see branding/packaging transitions across some legacy lamp lines during and after integration. SOSCleanroom will continue supporting specialty lamps and can assist with continuity validation by part number and critical specs.
