37-816 25.4mm Dia. x 75.0mm FL; Plano-Convex Lens Uncoated

The 37-816 is a Plano-Convex spherical lens, sourced from Edmund Optics, boasting a diameter of 25.4mm and a focal length of 75.0mm. This lens is designed for use in the visible light spectrum, specifically at a wavelength of 587.6nm.

The lens is crafted from the high-quality material, n-BK7 Schott, a borosilicate glass known for its excellent optical properties, including a low coefficient of thermal expansion and high homogeneity. This material ensures the lens delivers reliable and consistent performance across a wide range of temperatures and applications.

The lens geometry features a convex surface with a radius of curvature of 38.76mm, while the plano surface has an inner radius of 0mm and an outer radius of 0mm. The lens has a thickness of 1.36mm at the edge and 3.5mm at the center. The back focal length (BFL) measures 72.69mm, and the effective focal length (EFL) is 75mm.

Notably, this lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. While this may result in higher reflective losses, it also means the lens can be easily customized with coatings to suit specific application requirements.
