Plan Infinity corrected achromatic objectives
Coated with broadband multilayer AR for visible regions

Holmarc offers different types of infinity corrected objectives for high quality imaging and focusing applications. These objectives can also be used in fiber coupling, spatial filtering, and microscopy applications. Plan achromatic objectives are best suited for Brightfield observation with transmitted illumination, while plan achromatic metallurgical objectives and Long working distance plan apochromatic objectives and suitable for both epi-scopic(reflected light) and transmitted illumination applications.
