63-801 20mm Dia. x 35mm FL VIS-NIR Coated; UV Plano-Convex Lens VIS-NIR 400-1000nm
The 63-801 is a 20mm diameter, 35mm focal length plano-convex lens, specifically designed for use within the visible to near-infrared (VIS-NIR) spectrum, spanning 400-1000nm. This lens, sourced from Edmund Optics, boasts a high-quality fused silica material (fused sil mal-1965) known for its excellent transmittance and durability.
The lens features a front and back coating of edm visnir0sp2002000, which is a broadband anti-reflection coating, further optimizing its performance within the VIS-NIR range. The plano-convex geometry, with a 16.05mm radius of curvature, ensures minimal spherical aberration, delivering sharp and clear images.
The lens has a 1.5mm edge thickness and a 5mm center thickness, providing robustness and structural integrity. The inner and outer radii are both zero, indicating a uniform curvature across the lens surface. The back focal length (bfl) is 31.58mm, which should be considered when designing the optical system.
