23-865 25mm Dia. Fused Silica Precision Laser Aspheric Lens; EFL=75mm; NA=0.16 Laser V-Coat 532nm
This is the 23-865 model from Edmund Optics, a 25mm diameter Fused Silica Precision Laser Aspheric Lens, specifically designed for use with a 532nm wavelength and featuring a Laser V-Coat. The lens boasts an effective focal length (EFL) of 75mm and a numerical aperture (NA) of 0.16, making it ideal for high-precision laser applications.
The lens's geometry is optimized for performance, with an inner radius of 0mm, an outer radius of 0mm, a thickness at the edge of 3.78mm, and a center thickness of 5.5mm. The front and back surfaces are coated with the edm las v-coat 532, ensuring durability and efficiency in light transmission.
The lens's asphere is defined by a conic constant of -0.668 and a parabolic coefficient of 0. The front surface has a radius of curvature (R1) of 35.707mm, while the back surface (R2) is planar. The back focal length (BFL) is 70.9mm.
The lens is available in a circular shape, and the front and back surfaces are coated with the same edm las v-coat 532 for consistent performance. The lens is currently in stock, according to the vendor's website.
