33-965 25mm Dia. UVFS Aspheric Lens; EFL=17.5mm; NA=0.69 NIR 600-1050nm

The 33-965 is a high-performance aspheric lens, designed and manufactured by Edmund Optics. This lens boasts a 25mm diameter and a numerical aperture (NA) of 0.69, making it a versatile choice for a wide range of optical applications.

The lens is crafted from UV-fused silica, a material known for its exceptional transparency across a broad spectrum, including the near-infrared (NIR) region of 600-1050nm. This makes the 33-965 particularly suitable for applications that require high-quality imaging or light transmission in the NIR range.

The lens features a focal length (EFL) of 17.5mm, providing a good balance between field of view and focus. The aspheric design of the lens helps to minimize spherical aberration, a common issue in traditional spherical lenses, thereby improving image quality and resolution.

The 33-965 is coated with Edmund Optics' proprietary NIR coating, designed specifically for the 600-1050nm range. This coating enhances the lens's light transmission capabilities, reduces surface reflections, and protects the lens from environmental hazards.

In terms of geometry, the lens has an inner radius of 0mm, an outer radius of 0mm, and a thickness at the edge of 2.85mm. The thickness at the center is 14.8mm, and the lens has a front diameter of 0mm with an effective front diameter of 0.000135mm. The lens's front surface has a conic constant of -1.53, and the back surface has a conic constant of 0.

The 33-965 is available for purchase directly from the Edmund Optics website, where it is currently in stock. With its high-quality materials, advanced design, and reliable performance, the 33-965 is an excellent choice for any application that requires a high-performance aspheric lens in the NIR spectrum.
