62-472 6.25 mm Dia. N-BAF10/N-SF10 Negative Achromatic Doublet; EFL=-7.5mm MgF2 400-700nm

This is a 62-472 6.25 mm Dia. N-BAF10/N-SF10 Negative Achromatic Doublet, a high-quality optical lens sourced from Edmund Optics. The lens is designed with a diameter of 6.25 mm and a thickness of 4.98 mm at the edge, making it a compact and efficient option for various optical applications.

The lens is a negative doublet, meaning it has two negative lenses that are cemented together. This design helps to correct chromatic aberration, a common issue in optical systems where different wavelengths of light are focused at different points. The achromatic nature of the lens ensures that the image is clear and sharp, with minimal distortion.

The lens has an effective focal length (EFL) of -7.5 mm, which is the distance from the lens to the point where the light rays converge. This negative EFL indicates that the lens is a diverging lens, which spreads out the light rays. This can be useful in applications where a wider beam of light is required.

The lens is made from N-BAF10 and N-SF10 Schott glass, which are both high-quality optical materials known for their excellent transparency and low dispersion. The lens is coated with EDM MgF2 std curve on both the front and back surfaces, which helps to reduce reflection and increase transmission.

The lens is currently in stock and available for purchase through the Edmund Optics website. With its compact size, high-quality materials, and advanced design, this lens is an excellent choice for a wide range of optical applications.
