This is a 14BCV150-1-1 Double-Concave Lens from Standa, a renowned vendor in the optical industry. The lens is spherical in shape, featuring a base shape of a circle, and is designed for use in a wide range of optical applications.
The lens has a diameter of 25.4 mm and a center thickness of 3 mm, with the edge being slightly thicker at 4 mm. This lens is designed for use with a wavelength of 546 nm. The effective focal length (EFL) of this lens is -150 mm, indicating its concave nature. The radii of curvature for the first and second surfaces are -156.1206375 mm and 156.1206375 mm, respectively.
The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This makes the lens suitable for use in applications where high image quality and low distortion are required.
The lens does not come with any coating, which means it is uncoated. This may affect its performance in certain applications, particularly those involving high-intensity light sources or where high reflectivity is a concern. However, uncoated lenses are often preferred in applications where cost, simplicity, or specific optical characteristics are more important.
The lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website at http://www.standaphotonics.com/lenses/double-concave-lenses.php.
