Products/Services for polychromatic aberration
Achromats consist of two or more elements, usually of crown and flint glass, that have been corrected for chromatic aberration with respect to two selected wavelengths. They are also known as achromatic lenses. This area includes micro achromats as well. Search by Specification | Learn More
Monochromators are optical subassemblies used to isolate narrow portions of a light spectrum. They accept polychromatic input from a lamp or laser, and outputs monochromatic light. Learn More
