HO-BVL50-02 50mm Dia. N-BK7 Double-Concave Lens; EFL=-100mm Uncoated

The HO-BVL50-02 is a high-quality double-concave lens offered by Holmarc Opto-Mechatronics, a renowned vendor in the optical industry. This lens is specifically designed for applications that require a concave-concave spherical lens with a circular base shape.

The lens has a diameter of 50mm and a center thickness of 2.5mm, making it suitable for a wide range of optical systems. The effective focal length (EFL) of this lens is -100mm, indicating its diverging nature. This property makes it ideal for use in applications where beam expansion or divergence is required.

The lens is made from N-BK7, a popular optical glass type known for its excellent optical properties. This material is characterized by a high refractive index and low dispersion, making it a preferred choice for many optical applications.

The geometry of the lens includes radii of curvature of -105.759416mm and 105.759416mm for the first and second surfaces, respectively. The lens does not have any coating, which means it is uncoated. However, it can be customized with various coatings upon request to enhance its performance in specific applications.

The lens is designed to operate at a wavelength of 587.6nm, which is within the visible spectrum. It is important to note that the lens's performance can vary depending on the wavelength of the light it is intended to handle.
