67-330 40 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=750mm MgF2 400-700nm
The 67-330 is a high-quality achromatic doublet lens, boasting a 40 mm diameter and an effective focal length (EFL) of 750mm. This lens is meticulously crafted from two types of Schott glass, N-BK7 and N-SF5, ensuring superior optical performance. The achromatic design effectively minimizes chromatic aberration, a common issue in lens systems, resulting in clear, sharp images across the entire spectral range of 400-700nm.
The lens features a robust construction, with a thickness of 7.36mm at the edge and 4mm at the center. The inner and outer radii are optimized for optimal light transmission and image quality. The lens is coated with Edmund Optics' standard MgF2 coating, which provides excellent anti-reflection properties, further enhancing image quality and light transmission.
This lens is sourced from Edmund Optics, a renowned vendor known for their high-quality optical components. The lens is currently in stock, as indicated by the "weblink status" field in the item data. For more information, including pricing and availability, please refer to the provided weblink.
