HO-BXL25-01 25mm Dia. N-BK7 Double-Convex Lens; EFL=25mm Uncoated
The HO-BXL25-01 is a 25mm diameter, double-convex lens with a focal length of 25mm, sourced from Holmarc Opto-Mechatronics. This lens is made of N-BK7, a popular glass type in the optical industry known for its excellent optical properties, including low auto-fluorescence and a high Abbe number.
The lens features a base shape of a circle, with a thickness of 2mm at the edge. The inner and outer radii are both zero, indicating a symmetrical design. The first radius of curvature (R1) is 24.459612mm, and the second radius of curvature (R2) is -24.459612mm, which is typical for a double-convex lens.
The lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be advantageous in certain applications where the user wants to control the reflection or transmission characteristics of the lens themselves.
The lens is designed to operate at a wavelength of 587.6nm, which is in the yellow-green part of the visible spectrum. It is important to note that the performance of the lens can vary depending on the wavelength of light used.
