New 2024 Free Sample/Inquiry for Drawings Thermal Imaging Camera Germanium Lens Ge IR Lens Thermal Concave Convex

Product Description

2023 Export Quality OEM/ODM Service Factory Wholesale Price High-end Customization Thermal Imaging Camera Germanium Lens Lens GE IR Lens Thermal Concave ConvexProduct DescriptionThe plano concave lens is used to diverge the parallel light outward. The focal length of the flat concave lens is negative and the spherical aberration is also negative. It can be used to correct the phase difference, spherical aberration, coma and distortion of other lenses. Similar to the flat concave mirror, the side is generally opposite to the far object surface or infinity. K9 plano concave spherical lens can see the transmittance of near infrared (350-2000nm). H-K9L (N-BK7) is an optical glass commonly used in the preparation of optical elements. These uncoated plano concave lenses are prepared using H-K9L (N-BK7) conforming to ROHS standard. The collimated beam can converge on the rear focus, or the point light source can be changed into a collimated beam.
