BICC-25.4-103.4-C 25.4 mm Dia. N-BK7 Laser Grade Concave-Concave Lens; EFL=-100mm Uncoated
This is a high-quality concave-concave spherical lens, offered by CVI Laser Optics, with a catalog number BICC-25.4-103.4-C. The lens is designed for use in laser applications and is fabricated from N-BK7 Schott glass, a material known for its excellent optical properties. The lens has a diameter of 25.4 mm and a center thickness of 2.6 mm.
The lens's primary features include its concave-concave geometry, with radii of curvature of -103.4 mm and 103.4 mm, respectively. This geometry gives the lens an effective focal length (EFL) of -100 mm, making it suitable for use in various laser applications where a negative focal length is required. The lens is uncoated, which means it does not have any additional anti-reflective or protective coatings.
The item data also indicates a wavelength of 587.6 nm, suggesting that this lens is designed for use with yellow light. However, it's important to note that the lens's performance can vary depending on the specific wavelength and power of the laser it's used with. Therefore, it's always recommended to consult with the vendor or a qualified optical engineer when selecting lenses for specific laser applications.
