63-709-INK 10 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=40mm VIS 0° 425-675nm
The 63-709-INK is a high-quality achromatic doublet lens, boasting a 10 mm diameter and an effective focal length (EFL) of 40 mm, specifically designed for the visible light spectrum ranging from 425 to 675 nm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available for purchase on their official website.
This achromatic doublet lens is meticulously crafted from two distinct materials: N-BK7 and N-SF5, both from Schott. The lens features a sophisticated design, comprising three radii (r1, r2, and r3) and two distinct thicknesses (edge and center). The edge thickness measures 3.74 mm, while the center thickness is 3 mm, with an additional 1.5 mm at the center a. The inner and outer radii are both zero, indicating a circular geometry.
The lens is coated with the EDM VIS-0 STD CURVE coating on both the front and back surfaces, ensuring optimal performance and durability. The 63-709-INK is classified as a multiplet, a type of lens that comprises multiple elements to achieve superior optical performance.
