37-790 12.5mm Dia. x 30.0mm FL; Plano-Convex Lens Uncoated

The 37-790 is a Plano-Convex spherical lens, sourced from the renowned optical component vendor, Edmund Optics. This lens boasts a 12.5mm diameter and a 30.0mm focal length (FL), making it suitable for a wide range of optical applications.

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 is particularly suitable for applications that require high precision and durability.

The geometry of the lens is carefully designed, with a thickness of 1.39mm at the edge and 2.7mm at the center. The lens's inner radius is 0mm, and the outer radius is also 0mm, indicating a uniform curvature. The lens's effective focal length (EFL) is 30mm, and the radius of curvature (R1) is 15.51mm. The back focal length (BFL) is 28.22mm.

Notably, this lens is uncoated, offering users the flexibility to apply their preferred coating based on their specific application requirements. However, it's essential to consider that uncoated lenses may have lower transmission rates and are more susceptible to environmental factors such as dust and moisture.
