High performance air-spaced laser aplanat for UV and high power use; single wavelengths from 266-1064 nm. Designed to produce the minimum focal spot size, these fused silica air-spaced doublets exhibit essentially diffraction limited performances over their full f/5 apertures. They are available with a range of high performance AR coatings for use with very high power monochromatic light at UV through near-infrared wavelengths.
