OSRAM HBO 200 W/2 – Short arc mercury lamp (double terminal) for fluorescence microscopy and UV curing

The OSRAM HBO 200 W/2 is a 200 W short-arc mercury lamp designed as a high-luminance point source with a multiband spectrum in the visible and ultraviolet. Thanks to its high arc stability and high UV output, it is a benchmark in fluorescence microscopy , UV curing , and light guide illumination . It typically operates at 57 V with 3.0–3.5 A of current (DC or AC, depending on the equipment), delivers 9,500 lm and 1,000 cd , and uses SFc10-4 anode and cathode bases for precise mounting. The s90 burn-in position (anode down) and 102 mm mounting length facilitate integration into compact microscope housings and specialized UV sources.

Main features

• High luminance point source: very short arc with high intensity and UV radiation for efficient coupling to optics and fibers.
• Multilinear spectrum: intense emission in Hg lines in visible and UV; suitable for excitation of fluorophores.
• High arc stability: reproducible output in critical imaging and analysis applications.
• Electrical and photometric parameters: 200 W, 57 V, 3.0–3.5 A; 9,500 lm , 1,000 cd , typical efficacy ~47.5 lm/W.
• Construction and assembly: SFc10-4 bases (anode/cathode); LCL 40 mm ; Ø 17 mm ; total length ~ 125–128 mm ; mounting length 102 mm ; weight ~ 100 g .
• Working position: s90 with anode facing downwards .

Product benefits

• Powerful UV excitation: high ultraviolet and visible radiation for fluorescence and fast curing.
• Consistent image quality: stable arc that guarantees repeatability between sessions.
• Professional integration: standardized dimensions and SFc10-4 bases for easy replacement in compatible lamp houses.

Use cases

• Fluorescence microscopy: stable excitation illumination for multichannel filtering/analysis.
• UV curing: adhesives, coatings and photopolymerization in laboratories and light industry.
• Light guides/fiber optics: efficient coupling to light guides in medical and scientific equipment.

Frequently Asked Questions

What does s90 mean? It is the recommended burning position: vertical with the anode down , necessary for the stability and life of the lamp.

Can I use it with AC or DC? There are configurations for DC or AC ; always follow the specifications of your equipment's power supply/lamp.

What precautions should I take? It must only be operated in enclosed housings designed for HBO: the lamp operates at high pressure and emits UV . Avoid all direct exposure and follow the equipment manufacturer's instructions.

Safety and best practices

• For exclusive use in enclosed accommodations with appropriate filters and safety interlocks.
• Avoid touching the quartz; install with gloves and accurately align the LCL (40 mm) .
• Respect ventilation and orientation s90 (anode down) ; dispose of as mercury waste according to regulations.
