HO-BXL25-08C 25mm Dia. N-BK7 Double-Convex Lens; EFL=200mm Single Layer MgF2
The HO-BXL25-08C is a high-quality double-convex lens offered by Holmarc Opto-Mechatronics, a renowned vendor in the optical industry. This lens, with a diameter of 25mm, is designed for use in various optical systems that require a convex-convex lens shape.
The lens's geometry is defined by its outer diameter and thickness. The diameter is 25mm, while the thickness at the edge is 2mm. The effective focal length (EFL) is 200mm, making it suitable for applications that require a longer focal length. The first radius of curvature (R1) is 208.173759, and the second radius of curvature (R2) is -208.173759, indicating a symmetrical double-convex design.
The lens is made of N-BK7, a popular optical glass from Schott. This material is known for its excellent optical properties, making it a common choice for various applications. The lens is coated with a single layer of MgF2 on both the front and back surfaces, which enhances its transmission characteristics, particularly in the visible spectrum around 587.6nm.
The coating is specified as "hol mgf2 0 aoi," suggesting a broad angle of incidence (AOI) for the coating, ensuring high performance across a wide range of incident angles. The lens's shape is spherical, which is a common and versatile geometry in optical systems.
