LM01-25-200 25.4 mm Dia. N-BK7 Positive Meniscus Lens; EFL=200mm Uncoated
This is the LM01-25-200, a 25.4 mm diameter Spherical Lens with a Positive Meniscus shape, sourced from CeNing Optics. The lens is made of N-BK7, a popular glass type known for its excellent optical properties, particularly in the visible spectrum. The lens has a focal length (EFL) of 200mm, making it suitable for a variety of applications that require moderate magnification or beam bending.
The lens geometry is characterized by its base shape, which is circular, and its thickness. The edge thickness is 2.8mm, while the center thickness is 3.5mm. The lens's inner and outer radii are both 0, indicating a symmetrical design. The radii of curvature (R1 and R2) are 49.03mm and 90mm respectively, and the back focal length (BFL) is 197mm.
The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors. This may affect its performance in high-intensity or high-precision applications, but it can be beneficial in situations where cost or simplicity are primary concerns.
