BICX-FS19 38 mm Dia. x 50 mm FL; Uncoated; Double-Convex Lens

The BICX-FS19 is a high-precision, double-convex lens offered by WTS Photonics. This lens boasts a diameter of 38 mm and a focal length of 50 mm, making it suitable for a wide range of optical applications. The lens is uncoated, providing a clear, unaltered view of the light passing through it.

The lens's geometry is characterized by its base shape, which is circular, and its spherical shape. The radius of curvature for the first surface (r1) is 44.06 mm, while the radius of curvature for the second surface (r2) is -44.06 mm. The effective focal length (EFL) is 50 mm, and the back focal length (BFL) is 45.81 mm. The lens has a thickness of 3 mm at the edge and 11.61 mm at the center.

The lens is made of fused silica (mal-1965), a material known for its excellent optical properties, including high transparency and resistance to thermal shock. The wavelength for this lens is 546.1 nm.

Please note that the lens does not have any coating, which means it does not have any additional protection or enhancement features such as anti-reflective or scratch-resistant coatings. However, this also means that the lens does not introduce any additional chromatic aberrations or other optical distortions that could be caused by coatings.
