Design and manufacturing of optical lens

To design and manufacture optical relay lenses according to clients’ parameters of imaging sensor chip (chip size, pixel size) and clients features of optical system (exit pupil diameter, exit pupil distance and focusing range), to give optimum image correction and proper eye relief:

It is necessary for a high resolving power relay lens system with 5 pieces lens to well express the feature of a zooming microscope equipped with a high resolution sensor chip.
