The 66-334 is a high-precision aspheric lens offered by Edmund Optics, featuring a diameter of 40 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 40 mm and a back focal length (BFL) of 30.68 mm. The center thickness of the lens is 15.5 mm, while the edge thickness is 6.39 mm. The front and back surfaces of the lens are coated with BBAR 600-1050, a broadband anti-reflection coating that enhances transmission in the 600-1050 nm range.
This lens is currently in stock and available for immediate purchase through the Edmund Optics website. With its high-quality materials, advanced design, and reliable performance, the 66-334 is an excellent choice for a wide range of optical applications.
