Windows RSH Optronics offers the following windows for CO2 laser systems: AR Coated Windows Brewster Windows Protective Windows 12 Windows

13 AR Coated Windows These windows are frequently used in optical systems to separate the environment in one part of the system from another, such as to seal vacuum or high-pressure cells. RSH Optronics provide AR coated windows in other substrates and as uncoated windows. We also offer AR coatings at other wavelengths or wavelength bands. From the AR Coated window graph, the transmission at 0 incidence is given below: AR Coated Windows AR Coated Window Graph Specifications Standards Diameter Tolerance / Thickness Tolerance Edge Thickness Variation (ETV) <= 3 arc minutes Clear Aperture (polished) 90% of diameter Surface Figure at 0.63µm 1.0 fringe/0.5 fringe Scratch-Dig AR Coating Reflectivity per Surface at 10.6µm < 0.20% Standard AR Coated Windows Part Number Material Diameter Thickness inches mm Inches mm ARWZ-1 ZnSe ARWZ-2 ZnSe ARWZ-3 ZnSe ARWZ-4 ZnSe ARWZ-5 ZnSe ARWZ-6 ZnSe ARWZ-7 ZnSe ARWZ-8 ZnSe ARWZ-9 ZnSe ARWZ-10 ZnSe ARWZ-11 ZnSe Contact a RSH Optronics sales representative for exact specifications. 13

14 Brewster Windows Rectangular Brewster Windows are uncoated substrates used in an optical system at Brewster s Angle. It is used to separate the S polarization from the P polarization. While virtually all of the p - component of polarization is transmitted by a Brewster Window, most of the s - component is reflected. For ZnSe, 50% of the incident s-polarized light is reflected per surface. Ge, with a higher index of refraction, has an approximately 87% Fresnel reflection of the s-polarization component at 10.6µm. 14 Rectangular Brewster Window Specifications Standards Width Tolerance / Length Tolerance / Thickness Tolerance Parallelism (Plano) <= 3 arc minutes Clear Aperture (polished) 80% of diameter Surface Figure at 0.63µm Scratch-Dig Brewster Angle at 10.6µm For ZnSe = 67.4º For Ge = 76º For GaAs = 73º Standard Brewster Windows Width Power: 1 fringe per inch; Irregularity: 0.5 fringe per inch Length Power: 1 fringe per inch; Irregularity: 0.5 fringe per inch Part Number Material Width Length Thickness inches mm inches mm inches mm BWG-1 Ge BWG-2 Ge BWG-3 Ge BWG-4 Ge BWG-5 Ge BWG-6 Ge BWZ-1 ZnSe BWZ-2 ZnSe BWZ-3 ZnSe BWZ-4 ZnSe BWZ-5 ZnSe BWZ-6 ZnSe BWZ-7 ZnSe BWZ-8 ZnSe BWZ-9 ZnSe BWZ-10 ZnSe BWZ-11 ZnSe The angle at which p reflectance drops to zero, termed Brewster s Angle, can be calculated from: θb = tan -1 (n) Where, θb = Brewster s Angle, n = Material s Index of Refraction Contact a RSH Optronics sales representative for exact specifications.

24 Beam Splitters Beam Splitters are used to reflect a certain percentage of incident energy, while transmitting the remaining energy. RSH Optronics does not maintain a standard Beam Splitter stock as the performance of them is mainly dependent on the coating specifications. We offer Beam Splitters for 9.4µm and 10.6µm.
