With the continuous advancement of science and technology, especially the emergence of laser technology and its application in the optical field, the accuracy requirements for laser operation adjustment are constantly increasing. From classic optical technology to adaptive optical engineering, piezoelectric ceramic technology has been continuously expanding in the application fields of optical technology with its precise micro-nano control and ultra-high adjustment accuracy. The

piezoelectric deflection mirror uses piezoelectric ceramics as the driving element. It adopts a backlash-free flexible hinge parallel guide structure design internally. The external mechanical structure realizes single-axis or multi-axis angular deflection motion through the expansion and contraction of multiple internal piezoelectric ceramics, and compensates The small amount ensures that the deflection mirror has high movement accuracy and stability. It uses the built-in high-precision sensor to perform closed-loop control of to achieve sub-microradian resolution and microradian positioning accuracy.

According to the movement dimensions of piezoelectric deflection mirrors, piezoelectric deflection mirrors can generally be divided into three types of motion, namely one-dimensional θx axis deflection motion, two-dimensional θx θy deflection motion, three-dimensional θx θy deflection and Z-direction motion.

θx θy two-dimensional deflection

Core Tomorrow S38-C1 piezoelectric deflection mirror is a θx θy two-dimensional deflection piezoelectric fast reflex mirror. Its stroke range is divided into two types, namely 1.2mrad and 2.4mrad. The upgraded S38-C1 quick reflex mirror is more convenient. Moreover, the S38-C1 piezoelectric deflecting mirror is easy to integrate and can be integrated into the cage structure through a right-angle adapter.

Before and after the upgrade

Freely replaceable lenses

S38-C1 series piezoelectric deflection mirrors adopt a moving end thread structure design and are equipped with lens mounting caps. The lenses can be replaced according to user needs, unlike traditional piezoelectric deflection mirrors that require Compared with the lens that is bonded to the moving end surface and cannot be easily disassembled, the structural design of the replaceable lens of the S38-C1 piezoelectric deflection mirror increases convenience for users and makes the operation simpler.

Ultra-small size, high dynamics, suitable for airborne communications, imaging, environmental monitoring, etc.

S38-C1 series piezoelectric deflection mirrors are small in size, with an outer diameter of only 20mm and heights of 20mm and 29mm. Its no-load harmonic frequency can be as high as 7kHz, suitable for dynamic beam deflection applications. Its small size and dynamic nature make it suitable for airborne applications and can be used for airborne optical communications, optical imaging and environmental monitoring.

For example, for temporary network communication in emergency situations, the network can be built through drones, and the high dynamics and high deflection accuracy of the S38-C1 series piezoelectric deflection mirrors can quickly maintain the stability of the network. When imaging and taking pictures with a drone, you can also use the fast optical deflection of the S38-C1 fast reflex mirror to make the imaging clearer and more stable. When conducting environmental monitoring in remote areas, piezoelectric deflection mirrors provide a stable channel for data transmission.
