49-270 3 mm Dia. N-LAK22/N-SF6 Achromatic Doublet; EFL=4.5mm VIS 0° 425-675nm

The 49-270 is a high-quality achromatic doublet lens, boasting a 3 mm diameter and an effective focal length (EFL) of 4.5mm. This lens is specifically designed for the visible spectrum, covering wavelengths from 425 to 675nm.

The lens is composed of two elements, made from N-LAK22 and N-SF6 materials, both sourced from Schott. These materials are known for their excellent optical properties, contributing to the lens's overall performance.

The lens features a standard curvature coating on both the front and back surfaces, denoted as 'edm vis-0 std curve'. This coating is designed to enhance the lens's durability and optical performance, reducing surface reflections and improving transmission.

The lens's geometry is meticulously designed, with a thickness of 2.48mm at the edge, a center thickness of 2mm, and a center thickness 'a' of 1mm. The lens's radii are also precisely engineered, with r1 at 3.16mm, r2 at -2.23mm, and r3 at -7.88mm.

This lens is a multiplet, meaning it is composed of multiple elements. The multiplet design allows for superior optical performance, particularly in terms of chromatic aberration correction.
