Infrared Objectives (400 nm - 1400 nm)
OptoSigma's high Numerical Aperture (NA) near infrared (NIR) objectives are infinity corrected and designed for use with femtosecond and YAG lasers. These objectives have a long working distance and field curvature correction making them ideal for laser processing with coaxial imaging in the visible to monitor your processing. The NIR objectives are also available with glass thickness compensation if you are using a protective window or cover glass. These work very well for custom microscope configurations using our Modular Microscope System (OUCI).
