BICX213 25.4 mm Dia. x 500 mm FL; Uncoated; Double-Convex Lens
The BICX213 is a high-precision double-convex lens, characterized by its 25.4 mm diameter and 500 mm focal length (FL). Manufactured by WTS Photonics, this lens boasts a base shape of a perfect circle and is designed for use in spherical lens applications.
The lens's geometry is intricately detailed, with a thickness of 2 mm at the edge and 2.31 mm at the center. The effective focal length (EFL) is 500 mm, while the back focal length (BFL) is 499.21 mm. The radii of curvature for the first and second surfaces are 518.3 mm and -518.3 mm, respectively. The inner and outer radii are both zero, indicating a uniform curvature throughout the lens.
The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transmission properties and low auto-fluorescence. The wavelength for this lens is 546.1 nm. Notably, this lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, it can be customized with various coatings upon request.
