The BICX204 is a high-precision, double-convex lens offered by WTS Photonics. This lens boasts a diameter of 25.4 mm and a focal length of 50 mm, making it suitable for a wide range of optical applications. The lens is uncoated, providing a cost-effective solution for users who do not require additional anti-reflective or other coatings.
The lens's geometry is characterized by its base shape, which is circular, and its spherical design. The thickness at the edge of the lens is 2 mm, while the center thickness is 5.22 mm. The effective focal length (EFL) is 50 mm, and the radii of curvature are 50.93 mm for the first surface and -50.93 mm for the second surface. The back focal length (BFL) is 48.22 mm, and both the inner and outer radii are 0 mm.
The lens is made of n-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. The lens is designed to operate at a wavelength of 546.1 nm.
