HO-PXL12.5-3.2C 12.5mm Dia. N-BK7 Plano-Convex Lens; EFL=40mm Single Layer MgF2
This is a Plano-Convex lens from Holmarc Opto-Mechatronics, a leading manufacturer of optical components. The lens has a diameter of 12.5mm and a thickness at the edge of 2mm. The effective focal length (EFL) of this lens is 40mm, making it suitable for a wide range of optical applications.
The lens is made of N-BK7, a popular glass type in the optical industry due to its excellent optical properties. The curvature of the lens is spherical, with a radius of curvature (R1) of 20.865mm for the convex side. The inner and outer radii are both zero, indicating a plano surface on the other side.
The lens is coated with a single layer of MgF2 on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission, enhancing the performance of the lens in various applications. The coating is applied at 0 angle of incidence (AOI), ensuring uniform coverage and optimal performance.
The item data also provides a wavelength of 587.6nm, which is a common reference wavelength in optical design. This suggests that the lens is designed to perform optimally at this wavelength, although it can still be used for a broader spectral range.
