Product Description

2023 Factory Wholesale Price High-end customization Durable Optical Part For Concave Lens Diameter 8mm Focal Length-15.65mm Optical Glass Eyepiece Biconcave Lens For Student Physics Experiments (Diameter: 40mm/Focal Length: -41.9mm/Thickness: 2.5mm)
Product Description
New 2024 Free Sample/Inquiry for Drawings Dia 8mm FL-15.65mm Optical Glass Eyepiece Biconcave Lens (Dia 40mm/FL -41.9mm/Thickness: 2.5mm)
The 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.
