HO-BXL25-20 25mm Dia. N-BK7 Double-Convex Lens; EFL=500mm Uncoated

This is the HO-BXL25-20, a 25mm diameter N-BK7 double-convex lens with an effective focal length (EFL) of 500mm, sourced from Holmarc Opto-Mechatronics. The lens is uncoated, offering a unique set of optical properties.

The lens is a spherical design, featuring two convex surfaces. The first surface has a radius of curvature (R1) of 521.221508mm, while the second surface has a radius of curvature (R2) of -521.221508mm. The lens's thickness at the edge is 2mm. The inner and outer radii are both 0mm, indicating a symmetrical lens design.

The lens is made from N-BK7, a popular optical glass often used in high-quality optical systems due to its excellent optical properties. This type of glass is known for its low dispersion and high Abbe number, making it ideal for applications that require high image quality and color correction.

The lens is designed to operate at a wavelength of 587.6nm. This wavelength falls within the visible light spectrum, making the lens suitable for use in a wide range of optical systems that operate within this spectrum.

Please note that the lens is uncoated. This means that it does not have any anti-reflective coatings applied to its surfaces. While this can result in higher levels of reflection, it can also provide greater durability and simplicity, making it suitable for certain applications.

The lens is currently in stock and available for purchase. More information about this lens, including pricing and availability, can be found on the Holmarc Opto-Mechatronics website.
