33-947 15mm Dia. UVFS Aspheric Lens; EFL=10mm; NA=0.75 Uncoated

This is the 33-947 model from Edmund Optics, a 15mm diameter uncoated UV fused silica aspheric lens. The lens is designed with a high numerical aperture (NA) of 0.75, making it suitable for applications that require high light-gathering capabilities. The lens's effective focal length (EFL) is 10mm, which is a common choice for systems that need a compact, high-performance lens.

The lens's geometry is defined by its inner and outer radii, both of which are 0mm in this case. The lens's diameter is 15mm, and it has a thickness of 3.7mm at the edge, increasing to 11.4mm at the center. The lens's front surface has an aspheric shape, with a conic constant of -4.835 and higher-order aspheric terms of 0, 0, 0, and 1.18227e-10.

The lens is made of syn hpfs7980 corning, a material known for its excellent transmission properties in the ultraviolet (UV) range. This makes the lens ideal for UV applications, such as UV microscopy, spectroscopy, and other UV-based imaging systems.

The lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in higher reflective losses, it also means that the lens is less susceptible to damage from environmental factors, making it a good choice for harsh environments.
