CO2 laser optics | Laser Focus World

CO2 laser optics

Focusing lenses and mirrors for use in carbon dioxide laser systems are available in zinc selenide, germanium, and silicon with plano-convex, biconvex, and meniscus surfaces. Focal lengths range from 10 to 1000 mm, and outer diameters range from 10 to 75 mm. Antireflection or reflective coatings are available. The lenses and mirrors show 40/20 scratch/dig tolerances with 1/10 to 1/40 wave surface figure at CO2 laser wavelength.

Tracks of heavy ions 'imprinted' in lithium fluoride crystals. At the top, spot tracks observed under a fluorescence microscope in plates perpendicular to the heavy ion beam. At the bottom, the ion tracks in the parallel oriented plate (the blurring at both ends of the trace is an artifact of the depth of focus of the microscope). False colors.
