The 45-030 is a 25.0mm diameter Plano-Concave lens with a focal length of -25mm, sourced from the renowned optical vendor, Edmund Optics. This lens is a Spherical Lens, specifically designed in a Circular geometry, making it suitable for a wide range of optical applications.
The lens's geometry is meticulously crafted, with a thickness of 7.41mm at the edge and 3.5mm at the center. The back focal length (BFL) is -26.96mm, and the radius of curvature (R1) is -19.62mm. The lens does not have an inner or outer radius, indicating a uniform curvature throughout.
The lens is made from the high-quality material n-sf11 Schott, ensuring durability and excellent optical performance. It is designed to operate at a wavelength of 587.6nm. The lens is uncoated, providing a clear, unaltered optical path, although this may result in higher reflectivity compared to coated lenses.
