The 45-149 40.0mm Dia. x 60.0mm FL is a Plano-Convex lens, uncoated, sourced from the renowned optical components vendor, Edmund Optics. This lens, with a diameter of 40.0mm and a focal length of 60.0mm, is a Spherical Lens of the Sub Type Plano-Convex, featuring a Circular base shape.
The lens's geometry is meticulously crafted, with an edge thickness of 2.0mm and a center thickness of 9.31mm. The Effective Focal Length (EFL) is 60.0mm, and the Radius of Curvature (R1) is 31.03mm. The Back Focal Length (BFL) is 53.9mm, and both the Inner and Outer Radius are 0mm, indicating a plano surface.
The lens is made of the material n-BK7 Schott, a popular choice in the optical industry due to its excellent optical properties. The lens is uncoated, which means it does not have any anti-reflective or other coatings. This may be suitable for applications where such coatings are not required or desirable.
The lens is designed to work with a wavelength of 587.6nm. It is important to note that the performance of the lens can vary depending on the wavelength of the light used. Therefore, it is crucial to ensure that this lens is compatible with the specific wavelength of your application.
