1、 Nano level positioning accuracy: breaking through the limit of optical resolution
The core of digital confocal microscopy technology lies in achieving high-resolution cell display through three-dimensional reconstruction of sequential slice images, which requires high precision in objective lens positioning. Harbin Xinming's piezoelectric objective locator adopts piezoelectric ceramic driving technology, which converts electrical signals into mechanical displacements at the micrometer or even nanometer level through the inverse piezoelectric effect. Its product can achieveSeveral tens of nanometersThe stepping accuracy, combined with the built-in high-resolution encoder of the driver, can provide real-time feedback on the position of the objective lens, ensuring equidistant acquisition of sequence slice images.
For example, in three-dimensional imaging of cells, the objective lens needs to be aligned along the optical axis direction50-100Nano step size movement is used to obtain image data of different focal planes. The Xinming piezoelectric locator uses closed-loop control algorithm to control the positioning error within±5Within nanometers, it far exceeds the micrometer level accuracy of traditional mechanical stepper motors, effectively avoiding image blurring or reconstruction distortion caused by displacement errors.
2、 Millisecond response speed: adapted to high-speed dynamic scenes
In dynamic observation of living cells or high-speed semiconductor detection, the objective lens needs to quickly track the small displacement of the sample.
