Lenses Plano-Convex Lenses Plano-Convex Lens is widely used in laser heat treating, welding, cutting, and infrared radiation collection where spot size or image quality is not critical. For proper performance with a Plano-Convex Lens, the curved surface should face toward the incoming collimated beam or the longer conjugate distance (the object and image distances together are referred to as the conjugate distance).

Scanning Laser Systems Optics RSH Optronics provide scan lenses for CO 2 Laser systems that are used for applications like: Marking Engraving Rapid Prototyping Drilling circuit board via holes Cutting cloth, and Cutting paper In a typical scan lens configuration, the F-theta lens is used with one or two axis galvo mirrors that enable the laser beam fast positioning and precision focusing. While standard focusing lenses deliver a focused spot to only one point, scan lenses deliver a focused spot to many points on a scan field or workpiece. Wavelength options from 9.2 to 10.6µm. Via Hole Drilling diameters from 75 to 300µm. Low loss AR coatings. Optional protection windows. Scanning Laser Systems Optics RSH Scan Lenses 9

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 +0.000 /-0.005 Length Tolerance +0.000 /-0.005 Thickness Tolerance +0.005-0.010 Parallelism (Plano) <= 3 arc minutes Clear Aperture (polished) 80% of diameter Surface Figure at 0.63µm Scratch-Dig 20-10 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 0.50 12.7 2.00 50.8 0.08 2.03 BWG-2 Ge 0.60 15.24 2.50 63.5 0.08 2.03 BWG-3 Ge 0.70 17.78 2.90 73.66 0.08 2.03 BWG-4 Ge 1.00 25.4 4.10 104.14 0.12 3.05 BWG-5 Ge 1.50 38.1 3.90 99.06 0.16 4.06 BWG-6 Ge 2.00 50.8 5.20 132.08 0.20 5.08 BWZ-1 ZnSe 0.40 10.16 1.04 26.4 0.08 2.03 BWZ-2 ZnSe 0.50 12.7 1.30 33.0 0.08 2.03 BWZ-3 ZnSe 0.60 15.24 1.56 39.6 0.08 2.03 BWZ-4 ZnSe 0.70 17.78 1.82 46.2 0.08 2.03 BWZ-5 ZnSe 0.80 20.32 2.08 52.8 0.12 3.05 BWZ-6 ZnSe 0.90 22.86 2.34 59.4 0.12 3.05 BWZ-7 ZnSe 0.984 25 2.00 50.8 0.12 3.05 BWZ-8 ZnSe 1.00 25.4 2.60 66.0 0.12 3.05 BWZ-9 ZnSe 1.10 27.94 2.95 74.9 0.20 5.08 BWZ-10 ZnSe 1.50 38.1 3.91 99.3 0.16 4.06 BWZ-11 ZnSe 2.00 50.8 5.21 132.3 0.20 5.08 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.

Reflective Phase Retarders Reflective Phase Retarders are used in the beam delivery paths to convert the linear polarization to circular polarization. This requirement is mainly vital for laser material processing applications where cut or scribed edge quality, or weld penetration, is critical to the consistency and precision of the final part.

Reflective Phase Retarder Beam Expanders A Beam Expander is a two or more element optical system that changes the beam s size and divergence characteristics. Beam Expanders offer precise collimation of output beams in a compact Galilean design. RSH Optronics offers Beam Expanders for 10.6µm and 9.4µm. Features Low insertion loss High-power operation Visible transmission Adjustable focus (on some models) Minimum beam deviation Adjustable Beam Expanders The adjustable Beam Expander has advantage as the user is able to compensate for slightly convergent or divergent entrance beams by just adjusting the distance between the two ZnSe lenses via the focus ring. It has common connecting thread of M33x0.75, M16x0.75, M22x0.75, and M30x1. Suitable for Power Levels of Up to 100W. Focus Mechanism with Non-Rotating Optics. Included Scale to Measure Separation of Lenses. Adjustable Beam Expander Adjustable Beam Expander Technical Diagram 21

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.
