33-955 15mm Dia. UVFS Aspheric Lens; EFL=10mm; NA=0.75 UV-VIS 250-700nm

The 33-955 is a high-performance aspheric lens, designed and manufactured by Edmund Optics. This lens boasts a 15mm diameter and a numerical aperture (NA) of 0.75, making it a versatile choice for a wide range of optical applications. The lens is constructed from UV fused silica, a material known for its excellent transparency across the UV-VIS spectrum, spanning from 250 to 700nm.

The lens features a focal length (EFL) of 10mm, which, combined with its high NA, allows for a tight focus and high resolution. The aspheric design of the lens helps to reduce spherical aberration, a common issue in traditional spherical lenses, resulting in improved image quality and clarity.

The 33-955 is coated with Edmund Optics' standard UV-VIS coating on both the front and back surfaces. This coating enhances the lens's transmission across the UV-VIS spectrum, reducing reflection and improving overall light transmission.

In terms of geometry, the lens has an inner radius of 0mm, an outer radius of 0mm, and a thickness at the edge of 3.7mm. The thickness at the center is 11.4mm, and the back focal length (BFL) is 2.69mm. The lens's shape is defined by its aspheric profile, with coefficients k1 and k2 of -4.835 and 0, respectively.

The lens is currently in stock and available for immediate purchase through the Edmund Optics website. With its high-quality construction, advanced design, and wide spectral range, the 33-955 is an excellent choice for a variety of optical applications.
