36-735 18mm Dia x 36mm FL VIS-NIR Coated; UV Plano-Convex Lens VIS-NIR 400-1000nm

The 36-735 is a high-quality UV Plano-Convex Lens, 18mm in diameter and 36mm in focal length, designed for use in the visible to near-infrared spectrum (VIS-NIR), specifically covering the wavelength range of 400-1000nm. This lens is sourced from the reputable optical vendor, Edmund Optics.

The lens is constructed with a fused silica material (mal-1965) known for its excellent transmittance and durability. It boasts a base shape of a circle, with a diameter of 18mm, a thickness at the edge of 1.83mm, and a center thickness of 4.5mm. The effective focal length (EFL) is 36mm, and the radius of curvature (R1) is 16.51mm. The back focal length (BFL) is 32.92mm, and the lens has no inner or outer radius.

The 36-735 lens features a coating on both the front and back surfaces, specifically the EDM VISNIR0SP2002000 coating, which is designed to enhance its performance in the VIS-NIR spectrum. This coating aids in reducing surface reflections and increasing transmission, thereby improving the overall image quality.

This lens is a spherical lens, which means it has a spherical surface, and its geometry is plano-convex, meaning one side is flat, and the other side is curved. This design is often used to correct spherical aberration in optical systems.
