Visible Objectives (400 nm - 750 nm)
When you need long working distance and infinity correction in the visible wavelength range, OptoSigma's Visible Objectives are the answer. Our Visible Objectives are optimize for 400 to 700 nm and are offered with 45 mm or 90 mm parfocal distance. With chromatic aberration correction over the visible wavelength range, these objectives can be used for visible laser systems with coaxial observation. If you require long and ultra long working distance objectives for a zoom microscope, these are offered as well. Our visible objectives work very well for custom microscope configurations using our Modular Microscope System (OUCI).
