Realpoo Optics can manufacure square achromatic lens. Achromatic lens can be used as collimators, focusing lenses or light collectors. They are designed to eliminate chromatic and spherical aberrations and perform well for all paraxial imaging tasks. These lenses are coated with single layer antireflection coating to reduce surface losses in the visible regions. Achromatic lenses are widely used today in achromatic telescopes, microscopes, and photographic lenses.
