Laser Piezo Objective Scanner Micro Piezo Actuator Z Axis Piezoelectric Linear Stage Micrometer
P72 piezoelectric objective scanner is aZ-axis motion piezo positioner specially designed for objective lens focusing microscopy. It adopts africtionless flexible hinge parallel guiding mechanism, with ultra-high focusing stability. The objective positioner is loaded with amicroscopic detection/measurement or observation device to improve accuracy.
Characteristics
- Travel to 100μm
-Load capacity to 0.2kg
- Millisecond response time
-Closed loop for high repeatability
Typical Applications
- 3D imaging
-Interference/metering
-Surface structure analysis
-Confocal microscope
-Biotechnology
-Semiconductor test
Application Example
P72 piezoelectric objective scanner can be used for automatic cell microscopy, cold atom microscopy and so on.
Adapter Compatible
P72 objective positioner is connected to the objective lens through an adapter to quickly make the objective lens in the desired position. Avariety of thread adapters are available, such as M27×0.75, M26×0.75, M26×1/36", M25×0.75, W0.8×1/36", etc., and custom is available.
Small Size, High Dynamics
P72 Piezo Objective Scanner is very compact. Its body uses aflexible hinge mechanism, which is frictionless and has avery high resolution and it can carry 200g load for high-speed precision motion, it has been widely used in optical scanning, confocal microscopy and other fields.
Closed-Loop Step Time
Step time of 30ms at loading 200g to 100% travel.
