MicroSpot Objectives are supplied with high
energy-resistant, multilayer antireflection coatings optimized
for either a specific excimer laser wavelength or a broadband
range of wavelengths within the design spectrum. Standard
coatings are shown below. When ordering, replace the "λ" at the end of the part number with the appropriate wavelength
(nm) or coating code.
Transmission is more than adequate for video
monitoring in the visible. For use outside the UV design spectrum,
discuss with OFR.
Contact OFR for information concerning direct
and remote monitoring, and individual model performance at
