23-863 25mm Dia. Fused Silica Precision Laser Aspheric Lens; EFL=100mm; NA=0.125 Laser V-Coat 1064nm
This is the 23-863 model from Edmund Optics, a 25mm diameter Fused Silica Precision Laser Aspheric Lens, specifically designed for use with a 1064nm wavelength and featuring a Laser V-Coat. The lens boasts an effective focal length (EFL) of 100mm and a numerical aperture (NA) of 0.125, making it suitable for a variety of applications.
The lens's geometry is optimized for precision, with an inner radius of 0mm, an outer radius also of 0mm, and a thickness at the edge of 3.85mm. The EFL is 100mm, and the first radius of curvature (R1) is 47.609mm. The back focal length (BFL) is 96.3mm, and the thickness at the center is 6mm. The lens's conic constant (K1) is -0.67, and it has no secondary radius of curvature (R2).
The lens is coated with Edmund Optics' Laser V-Coat, designed for use with a 1064nm wavelength. This coating is applied to both the front and back surfaces of the lens. The coating ensures high transmission and low reflectivity, making it ideal for laser applications.
The lens's shape is aspheric, which allows for superior optical performance compared to traditional spherical lenses. This makes the lens particularly suitable for applications that require high precision and accuracy, such as laser systems, interferometry, and beam shaping.
