HO-PXL25-01 25mm Dia. N-BK7 Plano-Convex Lens; EFL=25mm Uncoated

This is the HO-PXL25-01 25mm Dia. N-BK7 Plano-Convex Lens, a high-quality optical component sourced from Holmarc Opto-Mechatronics. The lens, with a diameter of 25mm, is designed for use in a wide range of optical systems, thanks to its versatile specifications.

The lens is a Plano-Convex type, meaning it has one flat (plano) and one curved (convex) surface. This design is often used in optical systems to focus or collimate light. The curvature of the convex surface is defined by a radius of 13.04mm, which is a crucial parameter in determining the lens's optical performance.

The lens is made from N-BK7, a popular optical glass known for its excellent optical properties. This material is chosen for its high refractive index and low dispersion, making it ideal for a wide range of applications. The lens has an effective focal length (EFL) of 25mm, which is the distance from the lens's principal point to the focal point when the lens is used in air.

The lens is uncoated, meaning it does not have any anti-reflective coatings. While coatings can enhance the performance of a lens by reducing reflections and increasing transmission, uncoated lenses can be useful in certain applications where such enhancements are not required.

According to the vendor's website, this lens is in stock, ensuring quick delivery for those who need it. The lens's geometry, material, and coating make it a versatile and reliable choice for various optical applications.
