HO-BVL50-03C 50mm Dia. N-BK7 Double-Concave Lens; EFL=-150mm Single Layer MgF2

This is the HO-BVL50-03C 50mm Dia. N-BK7 Double-Concave Lens, a high-quality optical component sourced from Holmarc Opto-Mechatronics. The lens features a unique double-concave design, making it suitable for a wide range of applications where precise optical control is required.

The lens has a diameter of 50mm and a center thickness of 2.5mm, providing a substantial surface area for light interaction. The effective focal length (EFL) is -150mm, indicating that it is a diverging lens, causing incoming parallel rays to spread out after passing through it. This property is particularly useful in applications such as beam expansion, image projection, and optical power reduction.

The lens is made from N-BK7, a popular glass type known for its excellent optical properties. This material is characterized by a high refractive index and low dispersion, making it ideal for applications that require high image quality and color correction.

The lens features a single layer of MgF2 coating on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission, enhancing the lens's overall performance. The coating is applied using a highly precise process to ensure uniformity and durability.
