CoreMorrow Piezo Macro-Micro Combination Stage Suitable for Cage Structure!

With the development of piezo technology, researchers are no longer satisfied with the scene requirements of small displacement and high precision, and the demand for larger displacement stroke with high precision is constantly proposed. Such piezo products have also emerged as the times require with the development and progress of piezo technology. CoreMorrow XYZ72SN81K13 series piezo macro-micro combination stage adopts the combination of piezoelectric stick-slip principle and piezoelectric micro-motion technology to meet the XY axis millimeter-level large stroke, and achieve Z-axis nanometer-level high precision.

Features



· XY millimeter stroke, suitable for lateral adjustment of the lens

· Z micro-travel, suitable for optical focus adjustment

· Φ35mm aperture, suitable for transmitted light applications

· Voltage drive control, fast response and convenient operation


Macro-Micro Combination



XYZ72SN81K13 adopts macro-micro composite method, which perfectly combines piezoelectric stick-slip principle and piezoelectric micro-motion technology. Realize large stroke macro movement of XY stroke to ±5mm/axis,  Z axis can be adjusted by micro movement, and the stroke can reach 8μm.

• XY Millimeter Travel Motion, Piezo Screw Driving

XY axis is driven by the piezo screw designed and produced by CoreMorrow. It uses the stick-slip principle and has the characteristics of large stroke and high precision. Combined with the hollow sliding platform, the linear motion of the piezo screw is converted into the XY axis motion of the sliding platform.

Equipped with Cage structure Mounting Holes



XYZ72SN81K13 is specially designed for the application in the cage structure. The structure is equipped with cage structure mounting through holes, which can be directly integrated into the cage structure. It can be used to carry any optical element, such as carrying a lens in a cage structure, the movement adjustment in the XYaxis can precisely control the center position of the lens focus in the plane, and Z axismicro-motion enables precise nanoscale fine-tuning of the position of the focal point on the optical axis.

Application of Piezo Fiber Phase Modulator in Adaptive Optics Synthetic Aperture

Image
  In recent years, the optical synthetic aperture imaging technology has developed rapidly. It is a high-resolution imaging technology that uses multiple small aperture systems to synthesize a large aperture system through optical means. Optical synthetic aperture imaging technology makes the entire imaging system smaller and lighter. Therefore, it is also an important direction for the development of ground-based and space-based large-scale telescope systems. In the adaptive optics synthetic aperture imaging remote sensor system, factors such as the environment or the vibration of the carrier platform will cause the phase error of each sub-aperture in the synthetic aperture array, which will cause the image quality to deteriorate. Therefore, the improvement of imaging quality requires real-time measurement and correction of phase errors. CoreMorrow's piezoelectric ceramic fiber phase modulator can meet these requirements. Principle and Composition of Optical Synthetic Aperture Ima...

High Voltage Power Amplifier for Ultrasonic Gas Detection Applications

Image
  High-voltage power amplifiers (also known as power amplifiers, voltage amplifiers, etc., manufacturer: CoreMorrow) are amplifiers internally equipped with voltage and power amplifier circuits, which can amplify and output weak external analog signals (such as analog signals from signal generators). The gain of the high-voltage power amplifier can be as high as 180 times, and its output voltage value V, output frequency value f, etc. can be adjusted. Before introducing how high-voltage power amplifiers are used in ultrasonic gas detection, let's first understand the ultrasonic gas detection technology and its composition principles. Compared with the traditional ultrasonic gas detection method, the emerging technology adds a pair of ultrasonic sensors. This pair of sensors is placed in the unmixed background gas, and the distance between the sensors is exactly the same as that of the other pair of ultrasonic sensors. In this way, the synchronously emitted ultrasonic waves reach th...
