This is a high-quality Double-Convex Lens, type L-14BCX250-1.5-1, manufactured by Standa. The lens is spherical in shape, featuring a base shape of a circle, and is designed for use in a wide range of optical applications.
The lens has a diameter of 38.1 mm and a thickness at the edge of 3.4 mm. The center thickness is 5 mm, providing a robust structure suitable for various setups. The effective focal length (EFL) of this lens is 250 mm, making it ideal for applications requiring a longer focal length.
The lens is made of n-BK7 Schott glass, a material known for its excellent optical properties and high damage threshold. The radii of curvature for this lens are r1 = 258.49 mm and r2 = -258.49 mm, indicating a double-convex design. The inner and outer radii are both zero, suggesting a uniform curvature throughout the lens.
The lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This may be suitable for applications where such coatings are not required or desirable.
