This product is a Plano-Concave Spherical Lens, offered by CVI Laser Optics with the catalog number PLCC-15.0-77.3-C. It is a high-quality optical component designed for use in laser systems, featuring a 15 mm diameter and a center thickness of 2.3 mm. The lens has a concave shape with a radius of curvature of -77.3 mm, resulting in a negative focal length (EFL) of -150 mm. This makes it suitable for use in applications requiring diverging beams or negative magnification.
The lens is made from N-BK7 glass, a popular material for optical components due to its excellent optical properties and wide transmission range. The glass is uncoated, which means it does not have any additional anti-reflective or protective coatings. This may be suitable for applications where such coatings are not required or desirable.
The lens is in stock and available for immediate purchase. For more detailed specifications, please refer to the vendor's product datasheet, available at https://www.idexot.com/media/wysiwyg/cms-pages/pdf/2-Spherical_Lenses.pdf.
