The 49-277-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor Edmund Optics. This lens boasts a 5 mm diameter and an effective focal length (EFL) of 15 mm, specifically designed for the visible light spectrum, spanning 425-675 nm.
The lens is meticulously crafted from two distinct materials, N-BAF10 and N-SF10, both from Schott. These materials are known for their exceptional optical properties, contributing to the lens's high performance. The lens features a standard curve coating on both the front and back, specifically the EDM VIS-0 STD curve, further enhancing its optical capabilities.
The lens's geometry is intricately designed, with an inner radius of 0 and an outer radius of 0. The first radius (r1) is 10.67, while the second radius (r2) is -6.46, and the third radius (r3) is -53.57. The edge thickness is 2.22, the center thickness is 1.55, and the center thickness 'a' is 1.03.
The lens is available for purchase directly from the Edmund Optics website, and the link provided is valid and indicates the product is in stock. This lens is a multiplet, meaning it is composed of multiple optical elements, making it suitable for a wide range of optical applications.
