Product Description Optical Zinc Selenide Positive Meniscus Lenses for CO2 Laser ApplicationsSpherical LensesIR Lenses are used to collect, focus, or collimate light in the near-infrared, short-wave infrared, mid-wave infrared, or long-wave infrared spectra. Products are widely used in optical equipment, teaching, industrial lenses, camera, video shooting, automation, medical, measuring and surveying equipment, aviation, astronomy, etc.. So it requires different materials for different work range.Our products cover ultraviolet, visible light and infrared band.Product NameOptical Zinc Selenide Positive Meniscus Lenses for CO2 Laser ApplicationsSizeDia 1mm to 400mmMaterialZinc Selenide Due to its wide transmission band and low absorption in the red portion of the visible spectrum, Zinc Selenide (ZnSe) is commonly used in optical systems that combine CO2 lasers, operating at 10.6 μm, with inexpensive HeNe alignment lasers. Zinc selenide is transparent from 600 nm - 16 μm and is ideal for IR applications. It is also commonly used in thermal imaging systems. ZnSe also transmits some visible light, unlike germanium and silicon, thereby allowing for visual optical alignment. However, it is quite soft and will scratch easily. ZnSe has an index of refraction of 2.403 at 10.6 μm.Manufacturing accuracy of IR lenses or according to customer's need1.MaterialZinc Selenide or depends on customers' need2.Dimensional tolerances0/-0.05mm3.Surface flatnessLambda/4@633nm,per 25.4mm diameter 4.Clear aperture>90%5.Centration1 mintue6.Surface qualityInfrared 40-207.Edge Chip<0.1mm8.BevelBased on clients' requests9.CoatingApply Infrared AR coating or based on client requestsInspectionsApplication fieldFactory:Tianjin Tengteng Optoelectronic Technology Co., Ltd. was established in 1995, focused on production, research and sales of precision optics.
