High Power Air Spaced Laser Achromats

Air-spaced design provides superior color correction and performance Coatings are designed to resist damage from high power lasers Mounted in metal barrels for ease of use and pre-alignment Focal lengths from 50 to 200mm Clear aperture handles beams up to one inch in diameter

These laser Achromats are ideal for use with any laser operating in the visible spectrum. They will also serve as excellent general purpose imaging lenses for white light applications. These lenses are optimized for three wavelengths, 486.1, 587.6 and 656.3nm. A crown and a flint glass element are housed in a metal cell and separated by a spacer. The air gap acts as a third lens element and provides a greater degree of correction than found in a cemented lens. In this way it is possible to balance the aberrations over a fairly wide range of wavelengths so that the lenses perform well as broadband imaging devices. Not only are chromatic effects minimized but other paraxial aberrations can also be significantly reduced. As a result, these lenses provide excellent performance for focusing, imaging and light collection. Both elements are coated with a broadband multilayer AR coating which will withstand high power laser use.
