The 49-175 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens has a base shape of a circle and a diameter of 3mm, making it compact and versatile for various applications. The lens's thickness at the edge is 1.47mm, while its center thickness is 1.8mm, providing a balanced structure for efficient light transmission.
The effective focal length (EFL) of this lens is 4.5mm, which is the distance from the lens's center to the point at which the light rays converge. The first radius of curvature (R1) is 3.62mm, and the back focal length (BFL) is 3.5mm, contributing to the lens's overall optical performance.
The lens is made of n-lasf44 schott, a material known for its excellent optical properties. It is designed to work optimally with a wavelength of 587.6nm. The lens is coated with edm visnir0sp2002000 on both the front and back, enhancing its performance in the visible and near-infrared spectrum (VIS-NIR) range of 400-1000nm.
