Product Details
OurA-39NVariable Focus Lens is designed specifically for variable focus products needing a large clear aperture, long focal objectives, large sensors, C-Mount objective lenses, laser beam shaping, etc. It is perfectly suited for applications such as industrial vision, medical imaging cameras, optical equipment and biometric devices.
A-39N is based on Corning Varioptic’s breakthrough lens technology, allowing variable focus with absolutely no moving parts.
A-39N features 20 diopters of dynamic range, guaranteeing 5 cm focus ability and offers the same low power consumption, high shock resistance and fast focus ability that have led to the success of the A-Series Variable Focus Lenses.
