KBC076AR.33 50.8 mm Dia. x -200 mm FL; Double-Concave Lens Laser V-Coat 1064nm
The KBC076AR.33 is a high-quality double-concave spherical lens, designed with a 50.8 mm diameter and a focal length of -200 mm. This lens is sourced from the reputable vendor MKS/Newport, ensuring reliability and performance. The lens is fabricated from the renowned N-BK7 glass from Schott, a material known for its excellent optical properties.
The lens features a double-concave design, characterized by two concave surfaces. This design is particularly useful in applications that require beam convergence or divergence. The first surface has a radius of curvature of -207.148 mm, while the second surface has a radius of curvature of 207.148 mm. This specific curvature combination results in the lens's specified focal length of -200 mm.
The KBC076AR.33 is coated with the New AR-33 fromfigure on both the front and back surfaces. This anti-reflective coating is specifically designed for 1064 nm wavelength, reducing unwanted reflections and enhancing transmission. The coating ensures optimal performance in laser applications, making this lens an excellent choice for users working with this wavelength.
