Frequently asked

What is the OSRAM HBO 2510 W/NIL used for?

It is a 2500 W super-high-pressure mercury short-arc lamp used for i-line wafer steppers, published for Nikon NSR-2205 i14E.

Can you supply a replacement for the OSRAM HBO 2510 W/NIL?

Send us the part number, a photo of the lamp label and your exposure tool model. We match power, voltage, current, base, cable, overall length and light-centre length against the original before we quote, and state warranty hours on the quote.

How often should an exposure mercury lamp be replaced?

Typical rated life for high-power lithography and exposure lamps is 500 to 2,250 hours depending on type. UV output falls and arc stability degrades with age, which shows up as longer exposure times and non-uniformity, so plan replacement at rated life.

Safety: mercury short-arc lamps are under high pressure and contain mercury. Handle with face shield and gloves, keep the protective cover on until installed, and return used lamps for mercury recycling.
