HO-PVL12.5-2.4C 12.5mm Dia. N-BK7 Plano-Concave Lens; EFL=-30mm Single Layer MgF2

This is a Plano-Concave Lens from Holmarc Opto-Mechatronics, a leading manufacturer of optical components. The lens has a diameter of 12.5mm and a center thickness of 2.5mm, making it a compact and efficient optical element. The lens is made of N-BK7, a popular glass type known for its excellent optical properties, particularly its low dispersion.

The lens has an effective focal length (EFL) of -30mm, indicating that it is a diverging lens. This means that it spreads out light rays, making it ideal for applications such as beam expansion or collimation. The lens's concave surface has a radius of curvature of -15.648mm, which contributes to its diverging properties.

The lens is coated with a single layer of Magnesium Fluoride (MgF2), which is known for its high transparency and low reflectivity. This coating enhances the lens's performance by reducing surface reflections and increasing transmission. The coating is applied to both the front and back surfaces of the lens, ensuring optimal performance from all angles.

The lens is part of Holmarc Opto-Mechatronics' extensive catalog of optical components, which are known for their quality and reliability. The lens is in stock and ready for immediate shipping, as indicated by the "weblink status" field in the item data.
