30-229 23 mm Dia. N-F2/N-BK7/N-F2 Hastings Achromatic Triplet; EFL=40.3mm MgF2 400-700nm

The 30-229 is a high-quality Hastings achromatic triplet lens, boasting a 23 mm diameter and an effective focal length (EFL) of 40.3 mm. This lens is meticulously crafted from three Schott optical glasses: N-F2, N-BK7, and N-F2, ensuring superior optical performance. The lens is designed to minimize chromatic aberration, making it an excellent choice for a wide range of applications, particularly where high image quality is paramount.

The lens features a robust construction, with a thickness of 13.79 mm at the edge and varying thicknesses at the center, specifically 3.5 mm, 11 mm, and 3.5 mm, providing excellent structural integrity. The lens's geometry also includes inner and outer radii of 0 mm, and radii of 32.48 mm, 18.15 mm, -18.15 mm, and -32.48 mm, contributing to its impressive optical properties.

The 30-229 lens is coated with Edmund Optics' standard MgF2 coating on both the front and back surfaces, enhancing its light transmission capabilities within the 400-700 nm spectral range. This coating is designed to provide high reflectivity, low absorption, and excellent environmental resistance, ensuring the lens maintains its performance even in challenging conditions.
