33-946 25 mm Dia. L-BAL35 Precision Aspheric Lens; EFL=50mm; NA=0.25 BBAR 600-1050nm

The 33-946 is a high-precision aspheric lens, designed and manufactured by Edmund Optics. This lens is characterized by its 25 mm diameter and a numerical aperture (NA) of 0.25, making it suitable for a wide range of optical applications. The lens is made from L-BAL35, a material from Ohara, which is known for its excellent optical properties.

The lens has an effective focal length (EFL) of 50mm, which is the distance from the lens's principal point to the focal point when the lens is focused at infinity. This EFL makes the lens suitable for use in imaging systems where a moderate focal length is required.

The lens's geometry is also noteworthy. It has an inner radius of 0, an outer radius of 0, and a thickness at the edge of 2.8mm. The thickness at the center is 5.5mm, and the back focal length (BFL) is 46.54mm. The lens's shape is defined by its aspheric surface, which is characterized by a conic constant of -0.71 and a radius of curvature (R1) of 29.457.

The lens is coated with BBAR 600-1050, a broadband anti-reflection coating that reduces reflection across the 600-1050nm wavelength range. This coating enhances the lens's transmission, making it more efficient in transmitting light.

The lens is currently in stock and available for purchase. For more information, please refer to the vendor's website, linked below.
