The 32-908 is a 40mm diameter, 100mm focal length spherical lens, sourced from Edmund Optics. This lens is uncoated and features a convex-convex base shape, making it suitable for a wide range of optical applications.
The lens's geometry includes a thickness of 4.09mm at the edge and 8mm at the center, with an effective focal length (EFL) of 100mm. The first and second radii of curvature are 103.21mm and -103.21mm respectively, contributing to a back focal length (BFL) of 97.34mm. The lens's inner and outer radii are both zero, indicating a circular shape.
The lens is made from N-K5 Schott glass, a high-index, low-dispersion material often used in high-performance optical systems. It is designed to operate at a wavelength of 587.6nm. The lack of coating on this lens allows for greater customization in the optical system, as users can apply their own coatings to suit their specific needs.
