Baiyun Series
TEM Camera
[Pioneering China’s Electron Microscopy Industry]
透射电镜（TEM）相机是透射电子显微镜中用于捕捉和记录图像的关键部件。它安装在电镜的成像系统中，用于将经过样品后的电子信号转换为可观察和存储的图像。透射电镜相机的性能直接影响图像的质量、分辨率和信噪比，是现代电镜技术中不可或缺的一部分。
Against the backdrop of long-term reliance on imported technologies in this critical field, DRTem took the lead in independently developing high-performance, domestically produced TEM cameras—overcoming multiple core technological barriers. Our Baiyun Series products have been successfully applied in cutting-edge fields such as structural biology, advanced materials imaging, and semiconductor defect analysis. This marks a significant shift in China’s electron microscopy industry—from “usable” to truly “advanced” in core component innovation.
What are Indirect Electron Detection Cameras?
Indirect electron detection cameras are among the most traditional and widely used types of electron microscopy cameras. Their structure typically includes the following components: a scintillator screen, a prism or fiber-optic coupler, and a CCD or CMOS detector. The imaging process consists of the following steps:
1. The electron beam from the transmission electron microscope strikes the scintillator screen, converting the electron signal into a light signal.
2. The generated light signal is transmitted via an optical system (such as a lens or fiber-optic coupler).
3.The CMOS or CCD detector receives the transmitted light signal and converts it into a digital image.
