32-624 25mm Dia. x 50mm FL Uncoated; Double-Convex Lens
The 32-624 is a 25mm diameter, 50mm focal length uncoated double-convex lens, sourced from the renowned optical component vendor, Edmund Optics. This lens, with its spherical geometry, is a type of spherical lens that features a convex-convex base shape, ensuring a compact and efficient design.
The lens's geometry includes a diameter of 25mm, with a thickness of 1.88mm at the edge and 5mm at the center. The effective focal length (EFL) is 50mm, while the back focal length (BFL) measures 48.29mm. The first radius of curvature (R1) is 50.8mm, and the second radius of curvature (R2) is -50.8mm. The lens is made of the high-quality material N-BK7 Schott, a borosilicate crown glass known for its excellent optical properties.
The lens is designed to operate at a wavelength of 587.6nm. It does not come with any coating, which means it is in its raw state, providing bare minimum reflection control. However, this can be advantageous in certain applications where the user desires to apply their custom coating.
