HO-PXL25-1.6C 25mm Dia. N-BK7 Plano-Convex Lens; EFL=40mm Single Layer MgF2
This HO-PXL25-1.6C 25mm Dia. N-BK7 Plano-Convex Lens is a high-quality optical component sourced from Holmarc Opto-Mechatronics. It is a spherical lens with a base shape of a circle, designed for use in a wide range of optical applications.
The lens has a diameter of 25mm and a thickness at the edge of 2mm. The effective focal length (EFL) of this lens is 40mm, making it suitable for applications that require a longer focal length. The lens's front surface has a radius of curvature (R1) of 20.865mm, while the inner and outer radii are both 0mm, indicating a plano-convex design.
The lens is made from N-BK7 Schott glass, a popular choice for its high homogeneity, low auto-fluorescence, and excellent transmission properties in the visible and near-infrared spectral ranges. The glass has a refractive index of approximately 1.5168 at the specified wavelength of 587.6nm.
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 lens's performance in various applications. The coating's angle of incidence is 0 degrees, ensuring optimal performance across a wide range of incident angles.
