21-932 25mm Dia. UVFS Aspheric Lens; EFL=100mm; NA=0.11 UV 250-425nm
This is the 21-932 model from Edmund Optics, a 25mm Dia. UVFS Aspheric Lens with an effective focal length of 100mm and a numerical aperture of 0.11, specifically designed for use with UV light in the 250-425nm range.
The lens is made from HPFS7980 Corning, a high-performance fused silica material known for its excellent transmission properties in the UV range. The aspheric design of the lens helps to reduce spherical aberration, improving the overall image quality.
The lens has a diameter of 25mm and a thickness of 3.85mm at the edge, with a center thickness of 5.5mm. The front and back surfaces of the lens are coated with EDM UV 250-425nm, a coating specifically designed to enhance the lens' performance in the UV range.
The lens has an inner radius of 0mm and an outer radius of 0mm, with a back focal length of 96.3mm. The k1 and k2 values of -0.67 and 0 respectively, further contribute to the lens' ability to focus light accurately.
The lens is currently in stock and available for purchase through the Edmund Optics website.
