49-112 15 mm Dia. L-BAL35 Precision Aspheric Lens; EFL=22.5mm; NA=0.33 BBAR 600-1050nm

This is a high-precision aspheric lens, catalog number 49-112, offered by Edmund Optics. The lens boasts a diameter of 15 mm and a numerical aperture (NA) of 0.33, making it suitable for a wide range of optical applications. The lens is made from L-BAL35, a material from Ohara, and is designed for use at a wavelength of 587.6 nm.

The lens geometry is intricately designed with an inner radius of 0 and an outer radius of 0, ensuring optimal light transmission. It has a thickness of 1.8 mm at the edge and a focal length (EFL) of 22.5 mm, which is the distance between the lens and the focal point. The aspheric surface is defined by a conic constant of -2.364143, which helps to minimize spherical aberration and improve image quality.

The lens is coated with BBAR 600-1050, a broadband anti-reflection coating that reduces reflection across the 600-1050 nm wavelength range. This coating enhances the lens's light transmission capabilities, making it ideal for use in applications such as imaging, beam shaping, and laser systems.
