49-978 20mm Dia. x 35mm FL VIS 0° Coated; UV Plano-Convex Lens VIS 0° 425-675nm
This 49-978 optical lens, sourced from Edmund Optics, is a Spherical Lens of the Plano-Convex variety, designed with a Circular base shape. The lens boasts a diameter of 20mm, with a thickness of 1.5mm at the edge and 5mm at the center. The Effective Focal Length (EFL) is 35mm, and the Radius of Curvature (R1) is 16.05mm. The Back Focal Length (BFL) measures 31.58mm, while the Inner and Outer Radius are both 0mm.
The lens is crafted from Fused Silica (Mal-1965), a high-quality material known for its excellent transmission properties and durability. It is designed to operate within the wavelength range of 425-675nm, with a peak wavelength of 587.6nm.
The lens features a front and back coating of EDM VIS-0 STD CURVE, providing standard anti-reflection properties. This coating helps to minimize surface reflections, thereby enhancing the overall transmission efficiency of the lens.
