32-869 12mm Dia. x 36mm FL Uncoated; Double-Convex Lens
The 32-869 is a 12mm diameter, double-convex spherical lens with a focal length of 36mm, sourced from Edmund Optics. This uncoated lens is designed for use in the visible light spectrum, specifically at a wavelength of 587.6nm.
The lens's base shape is circular, with an edge thickness of 2.31mm and a center thickness of 3.3mm. The effective focal length (EFL) is 36mm, and the back focal length (BFL) is 34.9mm. The radii of curvature for the first and second surfaces are 36.65mm and -36.65mm, respectively. The lens does not have any inner or outer radius specifications.
The lens is made of N-BK7 Schott glass, a common material for optical lenses due to its excellent optical properties and wide transparency range. This lens is uncoated, meaning it does not have any additional layers to enhance its optical performance or protect it from environmental factors.
