The rear conjugate of these UV Microscope Objective Lenses is corrected for infinity, making them ideal for UV laser applications. Computer-optimized optical designs yield wavefront quality better than λ/5 from 350–1064 nm. The lenses are fabricated from UV grade fused silica for high power-handling capability. Damage threshold exceeds 8 J/cm2 with 12 nsec pulses at 1064 nm. The standard AR.10 antireflection coating is usable in the UV from 245–440 nm. The housing has a standard microscope objective thread for easy mounting.
These UV microscope objectives also offer excellent performance in the visible and near-IR with the proper antireflection coating. If your OEM application requires operation at other wavelengths, contact a Newport applications engineer for information about antireflection coating options.
