The KBX145AR.14 is a high-quality double-convex lens, sourced from the reputable vendor MKS/Newport. This lens, with a diameter of 50.8 mm, is designed for use in the visible spectrum, specifically optimized for wavelengths around 589 nm.
The lens features a double-convex geometry, with radii of curvature of 62.579 mm for both the front and back surfaces. This design results in a focal length of 62.9 mm, providing a substantial magnification effect. The lens has a central thickness of 13.773 mm and an edge thickness of 3 mm, ensuring robustness and durability.
The KBX145AR.14 is fabricated from the renowned material N-BK7 Schott, a borosilicate glass known for its excellent optical properties and chemical resistance. This material ensures high transmittance and low dispersion, making it ideal for a wide range of optical applications.
The lens is coated with a new AR-14 coating on both the front and back surfaces. This anti-reflective coating is designed to operate within the 430-700 nm spectral range, significantly reducing surface reflections and improving overall light transmission.
