49-275-INK 5 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=7.5mm VIS 0° 425-675nm
The 49-275-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 7.5 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's extensive catalog. These materials are known for their exceptional optical properties, contributing to the lens's high performance. The lens's front and back surfaces are coated with EDm VIS-0 standard curve coatings, further enhancing its light transmission capabilities.
The lens's geometry is intricately designed, with a thickness of 3.98 mm at the edge and 3.72 mm at the center. The center thickness reduces to 1.03 mm at the center a, providing a unique curvature that aids in its optical performance. The inner and outer radii are 0, indicating a circular shape.
This lens is a multiplet, meaning it is composed of multiple elements. The curvature of these elements is carefully calculated and executed to minimize optical aberrations, ensuring the lens delivers clear, sharp images.
