66-326 50 mm Dia. L-BAL35 Precision Aspheric Lens; EFL=50mm; NA=0.5 BBAR 425-675nm
This is the 66-326 model from Edmund Optics, a high-precision 50 mm Dia. Aspheric Lens made from L-BAL35 material. The lens boasts an effective focal length (EFL) of 50mm and a numerical aperture (NA) of 0.5, making it suitable for a wide range of applications that require high-resolution imaging and light gathering capabilities.
The lens features a BBAR coating (Broadband Anti-Reflection) optimized for the 425-675nm wavelength range, which significantly reduces surface reflections, improves transmission, and enhances overall optical performance. The lens has a center thickness of 19.4mm and an edge thickness of 8.01mm, providing excellent structural rigidity and stability.
The aspheric design of the lens (with a first radius of curvature of 30.85mm and a second radius of curvature of 500mm) helps correct spherical aberration, coma, and other optical aberrations, delivering superior image quality with high resolution and low distortion. The lens is also circular in shape, making it compatible with various optical systems and setups.
