HO-PVL12.5-04 12.5mm Dia. N-BK7 Plano-Concave Lens; EFL=-50mm Uncoated
This is a Plano-Concave Spherical Lens, sourced from Holmarc Opto-Mechatronics, a renowned vendor in the optical industry. The lens has a base shape of a circle and is designed for use in spherical optical systems.
The lens has a diameter of 12.5mm and a center thickness of 2.5mm. The effective focal length (EFL) of this lens is -50mm, indicating that it is a diverging lens, causing incoming light rays to spread out. The radius of curvature (R1) of the concave surface is -26.081mm. The lens does not have any coatings, as indicated in the item data.
The lens is made of N-BK7, a popular glass type in the optical industry due to its excellent optical properties. It is suitable for use in a wide range of wavelengths, with the item data specifying a wavelength of 587.6nm.
This lens is uncoated, meaning it does not have any anti-reflective coatings. While this may result in higher reflective losses, it can also make the lens more cost-effective.
Please note that the lens's inner and outer radii are both 0, indicating that this lens does not have any peripheral curvature.
For more information about this lens, including its availability and pricing, please refer to the vendor's website, which is provided in the item data.
