CO2 Laser Focusing Optic lense 2.5"FL for 10.6um wavelength Gallium Arsenide CO2 Laser Optics 1000 in stock, brand new & prime These optics are brand new, just manufactured in 11/2006. Perfect and flawless. Ready to use. Gallium Arsenide material, AR coated on both sides. Lens is for focusing a CO2 laser beam at 10.6um (1-11um effective) Diameter is 0.4705" or 11.951mm Thickness is 0.072" or 1.829mm We also sell laser tubes and power supplies, see our other listings. These optics are much better than Zinc Selenide optics for many reasons... see below for details. Two of these placed in a configuration back to back will collimate the beam for about 10+ inches which allows for excellent cutting of thick materials without worrying about adjusting a single focusing optic. The focal point can now be several inches instead of only a few millimeters. The example below uses two optics for collimation without use of a mirror. Absorption Coefficient, 1/cm at 10.6 µm Dielectric Constant at 300 K, high frequency Dielectric Constant at 300 K, static Thermal Conductivity, W/(m K) at 300 K Thermal Expansion, 1/K at 300 K Specific Heat, cal/(g K) at 273 K Click the Picture to visit our Listings The free listing tool.
