MML Zoom Lenses are high-performance lenses with integrated coaxial episcopic illumination designed based on telecentric optics.
Multiple zooming. long wrking distance. and an integrated coaxial episcopic illumination system that covers the entire view allow for recognition of all types of objects. Manual type products and electric zoom type ones with a stepping motor are available.
