Magnetic compass projection light tube
The working principle of the magnetic compass is based on the earth's magnetic field. The earth has a huge magnetic field, magnetic field lines from the south pole of the earth through the earth to the north pole. The magnetic compass uses this magnetic field to indicate direction.

Application Breakout Optical Hardware Boom Warms Up
3D visual perception technology was first used in the industrial field, mainly for high-precision three-dimensional measurement and small deformation measurement of objects and materials, etc. 3D visual perception is mainly used in three-dimensional scanning, small deformation measurement, bending angle measurement and analysis, positioning and navigation of industrial robots in the industrial field. At the end of 2023, Obi Zhongguang used large models of speech, language, vision-language, supplemented by data input from the company's Orbbec Gemini 2 series of depth cameras, to create a robotic arm capable of understanding and performing voice tasks.
Precautions for the prevention of chemical burns and glass cuts
Is a double-beam UV-Vis spectrophotometer suitable for the analysis of inorganic substances?
Double-beam UV-Vis spectrophotometer is a commonly used analytical instrument, which is widely used in chemistry, biology, environment and other fields. However, for the analysis of inorganic substances, there may be some limitations in the use of this instrument. This article will discuss this issue.
Quantum Precision Measurement: Change "Invisible" to "Visible"
Recently, the world's first commercial low-temperature scanning nitrogen-vacancy probe microscope was released in Hefei, Anhui. The instrument is mainly used to detect the surface magnetism of nanomaterials and will provide a new tool for research in materials science, condensed matter physics, life science and other fields. The instrument is independently developed by Chinese enterprises, marking a new breakthrough in the industrialization of quantum precision measurement technology in China.
