Laser Research Optics custom-manufactures CO2 laser optics in 9.3- to 10.6-µm wavelengths in sizes from ½- to 1-in. optical density (O.D.) and 0.070- to 0.12-in. thickness. The optics are suited for lasers operating at wavelengths that provide better performance in cutting plastic materials that are highly absorptive at a particular wavelength, such as Kapton and PET. Featuring laser-grade ZnSe, the optics have a 40-20 scratch-dig surface finish per MIL-PRF-13830 and 1/40-wave maximum flatness at 10.6 µm on two faces. Parallelism is 3 arcmin. Applications include cutting, welding, drilling, marking and materials processing. For more information, visit: www.laserresearchoptics.net
