33-950 25mm Dia. UVFS Aspheric Lens; EFL=50mm; NA=0.25 Uncoated
The 33-950 is a 25mm diameter aspheric lens, featuring a high-quality UV fused silica material (syn hpfs7980 corning) and a numerical aperture (NA) of 0.25. This lens is uncoated, offering a cost-effective solution for applications that do not require specialized coatings.
The lens has an effective focal length (EFL) of 50mm, making it suitable for various imaging and illumination applications. Its geometry includes an inner radius of 0mm, an outer radius of 0mm, and a thickness at the edge of 1.61mm. The center thickness is 5.13mm, and the back focal length (BFL) is 46.5mm.
The aspheric design of this lens, with a first-order aspheric coefficient (k1) of -0.62 and a second-order aspheric coefficient (k2) of 0, provides improved optical performance over spherical lenses, reducing spherical aberration and other optical aberrations.
The 33-950 lens is available from Edmund Optics and is currently in stock. For more information, including detailed specifications and purchasing options, please refer to the vendor's website using the provided weblink.
