Short-Arc Mercury Microscope Replacement Bulbs

High-luminance UV/visible lamps for fluorescence microscopy, analytical instruments, and photolithography systems.

Short-arc mercury lamps are specialty discharge lamps engineered to produce a tightly confined arc (high luminance) with highly stable output, making them a long-standing standard for demanding optical systems. In microscopy and analytical instruments, they are especially valued because mercury arc lamps deliver very intense spectral lines in the UV and visible regions—ideal for fluorescence excitation and high-contrast imaging. In semiconductor and microlithography applications, high-pressure mercury lamps are designed to concentrate output at commonly used UV wavelengths (notably around 436, 405, and 365 nm) that align with photolithography processes and exposure tool requirements.

Because these lamps operate with strong UV emission and high internal pressure, they must be used only in properly enclosed, purpose-designed housings and handled per the equipment manufacturer’s safety procedures.
