23-864 25mm Dia. Fused Silica Precision Laser Aspheric Lens; EFL=50mm; NA=0.25 Laser V-Coat 532nm
This product is a 25mm diameter Fused Silica Precision Laser Aspheric Lens, catalog number 23-864, available from Edmund Optics. The lens is specifically designed for use with a 532nm wavelength and features a Laser V-Coat for optimal performance.
The lens has an effective focal length (EFL) of 50mm, making it suitable for a variety of applications. The numerical aperture (NA) is 0.25, which contributes to its high light-gathering capacity. The lens is shaped as a circular asphere, which is known for its ability to reduce spherical aberration and improve optical performance.
The lens is made from fused silica, a material known for its excellent transmission properties and resistance to thermal shock. The inner and outer radii of the lens are 0, and the thickness at the edge is 3.82mm. The thickness at the center is 7.2mm, and the lens has a base shape of a circle.
The front and back of the lens are coated with edm las v-coat 532, ensuring optimal performance in its intended application. The lens has a shape of an asphere, which is a type of lens that has a surface with varying curvature, designed to eliminate spherical aberration and improve image quality.
The lens is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink.
