66-330 20 mm Dia. L-BAL35 Precision Aspheric Lens; EFL=20mm; NA=0.5 BBAR 600-1050nm
The 66-330 is a high-precision aspheric lens offered by Edmund Optics, featuring a 20 mm diameter 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 20 mm, which is the distance from the lens's principal point to its focal point. This EFL makes the lens suitable for a wide range of optical applications.
The lens's geometry includes a inner radius of 0, an outer radius of 0, a thickness at the edge of 3.44 mm, and a thickness at the center of 8 mm. The front and back surfaces of the lens are coated with BBAR (Broadband Anti-Reflection) coating, which enhances the transmission of light in the 600-1050 nm range.
The 66-330 is currently in stock and available for purchase through the Edmund Optics website. With its high-quality materials, advanced design, and reliable performance, this lens is an excellent choice for a variety of optical systems and applications.
