Product Overview
Objective and tube lenses are core components of imaging optical systems. Objective lenses capture and focus light from the sample with high numerical aperture and resolution, while tube lenses relay and project the image onto the sensor or intermediate plane. Together, they ensure high-quality imaging performance for metrology, inspection, and microscopy applications.
