The 45-348 is a high-quality achromatic doublet lens, 18 mm in diameter, designed and manufactured by Edmund Optics. This lens is a multiplet, meaning it is composed of multiple optical elements to achieve superior performance. The lens is specifically designed for use in the 400-700nm spectral range, making it suitable for a wide range of applications in the visible light spectrum.
The lens features a focal length of 30mm, indicated by the EFL (Effective Focal Length) parameter. The geometry of the lens is carefully crafted, with an inner radius of 0 and an outer radius of 0, ensuring optimal light transmission and minimal distortion. The lens has a thickness of 6.55mm at the edge and 6.91mm at the center, providing robustness and stability.
The lens is made from two types of high-quality Schott glass, N-BAF10 and N-SF10. These glasses are chosen for their excellent optical properties, including low dispersion and high transmission in the visible spectrum. The lens is coated with Edmund Optics' standard MgF2 coating on both the front and back surfaces, which enhances its light transmission capabilities and provides protection against environmental factors.
The 45-348 lens is currently in stock and available for immediate purchase through the Edmund Optics website. With its superior optical performance, robust design, and wide spectral range, this lens is an excellent choice for a variety of optical applications.
