OSRAM HBO 50 W/AC 39 V - Mercury Short Arc Lamp for Fluorescence Microscopy and UV Curing

OSRAM HBO 50 W/AC 39 V - Mercury Short Arc Lamp for Fluorescence Microscopy and UV Curing

The OSRAM HBO 50 W/AC 39 V is a short-arc mercury lamp (double-ended) designed for scientific and industrial applications requiring high radiance , an extremely intense light spot, and a multilinear spectrum in the visible and ultraviolet. Thanks to its compact design, it offers high UV and visible light output , high arc stability , and a precise geometry for coupling to light guides and optical systems for fluorescence microscopy , UV curing , laboratory analysis, and solar simulation. It operates at 39 V AC with a current of 1.1–1.3 A , delivering a typical luminous intensity of 230 cd and a luminous flux of 2,000 lm (typical photometric value for reference). Its rated life is 100 hours . It features SFa6-2 anode and cathode bases, a 22 mm LCL , a 10.0 mm diameter , and a 53.0 mm length (47.0 mm with the capless socket).

Main features

• High radiance and concentrated light spot: ideal for fluorescence excitation and coupling to optical fiber.
• Multilinear spectrum: intense lines in UV and visible; stable arc output.
• Standard scientific format: double SFa6-2 socket on both poles, LCL 22 mm for precise positioning.
• Compact and lightweight: Ø 10.0 mm , 53.0 mm long (47.0 mm without pins), weight 3.0 g .
• Burning position: s45 (respect the "UP" mark on the bulb for assembly).

Product benefits

• Intense and homogeneous fluorescent signal thanks to the high luminance of the short arc.
• Repeatability in tests due to arc stability and controlled emitter geometry.
• Easy integration into lamps and light modules with optical guides, collimators or excitation filters.

Use cases

• Fluorescence microscopy (epi/transmitted) with appropriate filters.
• UV curing of adhesives, resins and coatings.
• Fiber optic lighting for medical and laboratory instrumentation.
• Solar simulation and spectral analysis in R&D.

Frequently Asked Questions

• Does it require specific equipment? Yes. It must be used with compatible sources/igniters for short-arc mercury lamps and according to the manufacturer's guidelines.
• Can it be regulated? It is not designed for intensity regulation; it is used at nominal power with optical control in the system.
• What is its working position? s45 ; respect the “UP” mark on the bulb during installation.

Safety and recommendations

• Operate exclusively in enclosed housings designed for HBO lamps, with adequate shielding and UV filtering .
• The lamp operates at high internal pressure and emits UV light . Avoid direct/reflected exposure and use PPE.
• Contains mercury (Hg) ; manage end of life in accordance with applicable regulations.
