36-682 10mm Dia x 20mm FL Uncoated; UV Plano-Convex Lens
The 36-682 is a 10mm diameter, plano-convex lens with a focal length of 20mm, sourced from Edmund Optics. This lens is uncoated and optimized for use with UV light, specifically at a wavelength of 587.6nm.
The lens's geometry is characterized by a thickness of 1.52mm at the edge and 3mm at the center. The inner radius is 0mm, while the outer radius is also 0mm, indicating a sharply curved convex surface. The lens's back focal length (BFL) is 17.94mm, and its effective focal length (EFL) is 20mm. The radius of curvature (R1) is 9.17mm.
The lens is made of fused silica, identified as "fused sil mal-1965" in the material database. This material is known for its high transparency in the UV region, making it suitable for applications that require the transmission of UV light.
Please note that this lens is uncoated, which may affect its performance in certain applications. Uncoated lenses can be more susceptible to surface reflections and may not perform as well in high-intensity light situations. However, they are often more cost-effective and can be a good choice for applications where these factors are not critical.
