33-954 25mm Dia. UVFS Aspheric Lens; EFL=50mm; NA=0.25 UV 250-425nm
This is the 33-954 model from Edmund Optics, a 25mm Dia. UVFS Aspheric Lens with an effective focal length (EFL) of 50mm and a numerical aperture (NA) of 0.25, designed for use with UV light in the wavelength range of 250-425nm.
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, providing superior image quality compared to traditional spherical lenses.
The lens has a diameter of 25mm and a thickness of 1.61mm at the edge, with a center thickness of 5.13mm. The front and back surfaces of the lens are coated with EDM UV 250-425nm coating, which enhances its transmission properties in the specified UV range.
The lens has an inner radius of 0mm and an outer radius of 0mm, with a front surface radius of curvature (R1) of 22.93mm and a back surface radius of curvature (R2) of 0mm. The back focal length (BFL) of the lens is 46.5mm.
The lens is currently in stock and available for purchase through the Edmund Optics website.
