66-336 50 mm Dia. L-BAL35 Precision Aspheric Lens; EFL=50mm; NA=0.5 BBAR 600-1050nm
The 66-336 is a high-precision aspheric lens offered by Edmund Optics, featuring a diameter of 50 mm and a numerical aperture (NA) of 0.5. This lens is designed for use in the near-infrared (NIR) region, specifically at a wavelength of 587.6 nm.
The lens is made from L-BAL35, a material from Ohara, which is known for its excellent optical properties. The aspheric design of the lens helps to reduce spherical aberration, providing superior image quality.
The lens has an effective focal length (EFL) of 50 mm and a back focal length (BFL) of 38.33 mm. The center thickness of the lens is 19.4 mm, while the edge thickness is 8.01 mm. The front and back surfaces of the lens are coated with BBAR 600-1050, ensuring high transmission and low reflectance in the NIR region.
This lens is ideal for applications that require high-resolution imaging in the NIR region, such as spectroscopy, beam shaping, and optical profiling. It is available for purchase through the Edmund Optics website, where it is currently in stock.
