33-918 75 mm Dia. N-BAF10/N-SF57 Achromatic Doublet; EFL=100mm MgF2 400-700nm

The 33-918 is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens is designed with a base shape of 75 mm diameter and a focal length of 100 mm, making it suitable for a wide range of optical applications.

The lens is composed of two types of glass, N-BAF10 and N-SF57, both from Schott. This combination is strategically chosen to minimize chromatic aberration, a common issue in optical systems where different wavelengths of light are focused at different points. The achromatic design ensures that the lens focuses both red and blue light to the same point, providing sharper images and improved color correction.

The lens features a front and back coating of edm mgf2 std curve, which is a type of anti-reflective coating. This coating enhances the lens's performance by reducing light loss due to reflection, thereby increasing the amount of light transmitted through the lens. The coating also provides protection against environmental factors, such as dust and moisture, thereby extending the lifespan of the lens.

The geometry of the lens includes a thickness of 24.66 mm at the edge, a center thickness of 26 mm, and a center thickness 'a' of 12.7 mm. The lens's inner and outer radii are 0, indicating a symmetrical design. The lens's shape is classified as a multiplet, which refers to a lens system composed of multiple elements.

The lens is currently in stock and available for purchase. For more information, please refer to the vendor's website provided in the item data.
