Introduction High-power CO2 laser optics The laser-optics division of Paul Pleiger Maschinenfabrik GmbH & Co. KG in Witten on the River Ruhr, supplies ready-to-use optical components for CO2 lasers throughout the world and coats customer s substrates for the complete near and far infrared ranges. We offer the following parts optimized for high-power CO2 lasers: Lenses: ZnSe, Ge, GaAs Windows: ZnSe, Ge, GaAs Cavity Optics: Si, ZnSe, Ge, GaAs High Reflection Mirrors: Si, Be Reflective Phase Retarders: Si Zero Phase Retarders: Si Output Coupler: ZnSe, Ge, GaAs Rear Mirror: ZnSe, Ge, GaAs Lenses We offer plano convex and meniscus lenses for focusing high-power CO2 laser beams for processing materials (cutting, welding). The ZnSe material used is exclusively of "CVD Laser Grade" quality with the very lowest absorption characteristics. Nonstandard focal lengths, diameters and specifications can be offered on request. Mirrors The manifold different applications for our mirrors, include cavity optics such as back mirrors, folding mirrors and output couplers. In addition we offer external optics such as beam benders, 90 phase retarders and telescope mirrors. On offer are partially reflecting mirrors / beam splitters and end mirrors with low residual transmission. Coatings All high-power optics manufactured by Pleiger are given our PICO coatings, which we are also be pleased to apply to substrates supplied to us. We carry out the coating process in one of the most modern high-vacuum coating units with precise monitoring of the layer thickness and automated monitoring systems. PICO HR: High Reflector Coating PICO HR DB: Double Band Coating PICO RPR: 90 Phase Retarder PICO ZPS: Zero Phase Coating PICO PLM: Polarization Locking PICO OC: Output Coupler Coating PICO ARLA: Anti-Reflection Coating Without exception we use exclusively non-radioactive coating materials from well-known manufacturers. Quality assurance Our measuring and testing devices cover all the parameters required for the production of high quality products.

Cleaning General: All materials used for infrared optics are fragile - whether single crystal or polycrystalline - large or fine grained. They are not as strong as glass and will not withstand procedures normally used on glass parts. Infrared optics should never be touched. Always wear powder-free finger cots or surgical gloves. Dirt and oil from the skin can severely contaminate optics, causing a major reduction in performance. Do not use any tools to handle optics. Always place optics on the lens tissue supplied for protection. Never place optics on a hard or rough surface. Infrared laser optics can be easily scratched. Bare gold or bare copper should never be cleaned or touched. Cleaning Note: Except for Method 1, the cleaning procedures described here should not be used for new optics. New optics are cleaned and packaged prior to dispatch to ensure their high quality condition upon receipt. If you suspect a problem with contamination, or other cosmetic defects with a new optic, please contact Pleiger immediately. Method 1 - Mild Cleaning for Light Contamination (dust, lint particles) Use an air bulb to blow off any loose contaminants from the surface of the optic before proceeding to the cleaning steps. If this step does not remove the contamination, continue to Method 2. Note: Avoid using shop air lines because they usually contain significant amounts of oil and water. These contaminants can form detrimental absorbing films on optical surfaces. Method 2 - Mild Cleaning for Light Contamination (smudges, fingerprints) I. Dampen an unused cotton swab or a cotton ball with acetone or i-propanol. II. Gently wipe the surface with the damp cotton. Do not rub hard. III. Drag the cotton across the surface just fast enough so that the liquid evaporates right behind the cotton. This should leave no streaks. If this step does not remove the contamination, continue to Method 3. Note: Use only paper-bodied cotton swabs and high-quality surgical cotton balls. Reagent grade acetone and i-propanol are recommended. www.pleiger-laseroptik.de P: +49 2324 398-406 F: +49 2324 398-402 E: info@pleiger-laseroptik.de Page 15
Method 2 (alternative method) "Drop and Drag " - Mild Cleaning for Light Contamination Note: The "Drop and Drag" method is not a preferred cleaning method. Cleaning I. Lay a piece of lens tissue on the surface of the optic. II. Using an eyedropper, squeeze a few drops of acetone onto the lens tissue, so that the complete diameter of the optic is wetted. III. Without lifting the lens tissue, drag the lens tissue across the optic just fast enough so that the liquid evaporates behind the tissue. This should leave no streaks. If this step does not remove the contamination, continue to Method 3. Note: Use only the lens tissue supplied in the optics cleaning kit or another high-quality lens tissue. Reagent grade acetone is recommended. Method 3 - Moderate Cleaning for Moderate Contamination (spittle, oils) I. Dampen an unused cotton swab or cotton ball with white distilled vinegar. II. Using light pressure, wipe the surface of the optic with the damp cotton. III. Wipe away excess distilled vinegar with a clean dry cotton swab. IV. Immediately dampen a cotton swab or cotton ball with acetone. V. Gently wipe the surface of the optic to remove any acetic acid. Note: Use only paper-bodied cotton swabs. Use only high quality surgical cotton balls that have been sorted to remove any with embedded abrasives. White distilled vinegar with 6 % acidity should be used. Examination of Cleaned Optic The final step is to carefully examine the surface of the optic under good light in front of a black background. Note: Certain types of contamination and damage such as metal splatter, pits, etc, cannot be removed. If the optic shows this type of contamination or damage, it will probably need to be reworked or replaced. If reworking of an optic is necessary, contact Pleiger to make arrangements to return the part for repolishing and recoating.
