32-707 18mm Dia. x 27mm FL Uncoated; Double-Convex Lens
The 32-707 is a high-quality spherical lens, boasting a double-convex design and a base shape of a circle. This lens, sourced from the reputable vendor Edmund Optics, is a 32-707 model with a diameter of 18mm and a focal length of 27mm. The lens is uncoated, offering users the advantage of customizing their own coating or utilizing it in environments where coating is not necessary.
The lens's geometry is meticulously crafted, with a thickness at the edge of 2.42mm and a center thickness of 5.5mm. The effective focal length (EFL) is 27mm, and the radii of curvature are R1: 27.08mm and R2: -27.08mm. The back focal length (BFL) is 25.25mm, and both the inner and outer radii are 0mm, indicating a symmetrical design.
The lens is made of n-BK7 Schott material, a popular choice for its high refractive index and low dispersion. It is optimized for a wavelength of 587.6nm, making it suitable for a wide range of applications, particularly in the visible light spectrum.
