The characteristics of
● Maximum travel 110um
● Maximum load capacity: 200 GB
● millisecond response time
● High precision of closed loop repetitive positioning
● Good focusing stability
Typical applications
● Three-dimensional imaging
● Interference/metering
● Surface structure analysis
● Confocal microscopy
● Biotechnology
● Semiconductor testing
Fast installation, high stability, long service life
The WNXP-721 piezoelectric objective positioner is a general microscopic imaging focusing positioner, which is driven by piezoelectric ceramics and can achieve a scanning range of 1 10μm.
The WNXP-721 piezoelectric objective positioner is compact in size, compact in structure, and cost-effective, and can be matched with many specifications and models of microscopic objectives on the market.
The product is installed between the lens connecting frame and the objective lens through a threaded adapter. The objective locator body is threaded to the lens rotation frame, and then the objective is connected to the locator. This design makes it necessary to remove the objective without removing other components.
Objective positioner built-in high reliability piezoelectric ceramics, combined with excellent mechanical structure, with good stability, long service life and other advantages.
