Gravity compensation up to 1kg Voice coil focus stage V-308
High-precision Z-axis supporting fine observation with a minimum movement of 10nm, maximum travel of 7mm, and passive holding up to 1kg.
The V-308 is a Z-axis focus stage that combines voice coil direct drive and cross roller guides. With a minimum increment of 10 nm and an adjustable stroke of 7 mm, it allows for optimization of the focal position of optical systems at the nanometer level. It provides high reliability for multiphoton and deep tissue imaging using large-diameter lenses or long working distance lenses. The high rigidity structure of the cross roller guide and the 10 nm resolution encoder ensure smooth nanopositioning across the entire 7 mm range.
