WNP72 series piezoelectric objective locator is specially designed for the objective lens focusing on microscopic Z axis movement piezoelectric objective locator, using no return difference of flexible hinge design oriented parallel mechanism, the objective lens compensation quantity is small, be very focused on the stability, objective locator in microscopic inspection/measurement or observation device can take animal lens focus to improve accuracy, It can be used with a variety of high resolution microscopes.
The characteristics of
● Maximum stroke 110μm
● Maximum load capacity 0.2kg
● millisecond response time
● High precision of closed loop repetitive positioning
● Open/closed loop optional
Typical applications
● Three-dimensional imaging
● Interference/metering
● Surface structure analysis
● Confocal microscopy
● Biotechnology
● Semiconductor testing
Compact size, easy to integrate, high dynamic, good linearity
The WNP72 piezoelectric objective positioner is compact in size and can achieve a maximum displacement of 110μm. Multiple threaded connectors are available for easy integration with other optical microscopes.
The platform adopts flexible hinge mechanism, which is frictionless and has extremely high resolution. Because its no-load resonant frequency can reach 350Hz, and can carry 200g load for high-speed precision motion, it has been widely used in optical scanning, confocal microscopy and other fields.
Closed-loop version is available to achieve ultra-high positioning accuracy.
