Achromatic lenses are expertly crafted by cementing two or more elements to effectively eliminate chromatic and spherical aberrations. By precisely focusing multiple wavelengths onto a single focal plane, they deliver exceptionally sharp, high-contrast images with accurate color reproduction. Designed to outperform standard single lenses, our achromats provide the superior clarity and optical precision required for high-resolution microscopes... morehttps://www.hp-lens.com/products/achromatic-lenses/

PRODUCT DRAWING OF
Achromatic Lenses
Example with BK7 material: These N-BK7 biconvex lenses are available uncoated or with one of five antireflection coatings (-A, -AB, -B, -C, or -D), which reduce the amount of light reflected from each surface of the lens (see the Selection Guide table below for coating option). Since approximately 4% of the incident light is reflected at each surface of an uncoated substrate, the application of an AR coating improves transmission, which is important in low-light applications, and prevents the undesirable effects (e.g., ghost images) associated with multiple reflections. Having optics that are AR coated on both surfaces is particularly desirable for applications utilizing multiple optical elements. Please see the Graphs tab for additional coating information.
