BEX-8503 electron charge-to-mass ratio experiment apparatus
The central component of the electron charge-to-mass-ratio apparatus is a three-dimensional Wei'erni tube that visibly displays electron-beam trajectories. Place the tube in the field of Helmholtz coils and apply voltage to its electron gun to emit a beam for experimentation. The apparatus has a modular power supply, an easily replaceable tube, a highly uniform field, and an illuminated adjustable mirrored scale. CE certification supports safe, reliable operation.

BEM-5032A teslameter Measurement Devices Brolight
Measurement Range: 0-2000mT Accuracy: 0.1mT
The BEM-5032A teslameter measures magnetic flux density and is commonly used to assess fields from permanent magnets and electromagnetic sources. Principle: Based on the Hall effect. When current flows through a conducting material in a magnetic field, charges are deflected, producing a potential difference, the Hall voltage, across the material. Measuring this voltage determines magnetic-field strength.

BEX-8105 metal thermal expansion coefficient experiment apparatus Measurement Devices Brolight
Metal thermal-expansion-coefficient experimental apparatus - Input: Wide input voltage range 110~220V Metal thermal-expansion-coefficient experimental apparatus - Temperature-measurement module: Temperature measurement range from room temperature to 100℃ Metal thermal-expansion-coefficient experimental apparatus - Displacement-measurement module: Microdisplacement sensor measurement range 0-10.000mm
This teaching apparatus determines metal linear-expansion coefficients by heating copper, aluminum, and stainless-steel sample tubes with steam and directly measuring small elongations with a micrometer. It comprises a steam generator, metal sample tubes, temperature sensor, and small-displacement sensor. Small sample changes are measured dynamically during stable cooling, with 2 digital displays showing temperature and displacement in real time. Digital sensors can also record live displacement and temperature curves. Steam-based thermal-expansion measurement avoids scale buildup, pipe blockage, and leaks. An acrylic protective housing ensures safety. Displacement accuracy is 0.001mm. Three easily replaceable samples—aluminum, brass, and stainless steel—make experiments efficient and intuitive.

A solid-state laser is one of the most common and reliable laser types used in modern industry, medical equipment, and scientific research. Unlike gas or fiber lasers, it uses solid materials as its gain medium to generate stable, high-brightness laser beams. Thanks to its high precision, long lifespan, and compact structure, solid-state lasers have become a mainstream solution for high-precision laser processing and optical systems.
In photonics and laser technology, devices that manipulate optical signals via the electro-optic effect form the backbone of precision optical systems. Electro-optic phase modulators and electro-optic deflectors are two prominent examples of this device category. As a critical hardware solution for high-speed, high-accuracy laser beam direction control, electro-optic deflectors are widely deployed across industrial and research settings. Below is a detailed overview of their core structure, key performance drivers, and primary use cases.
In UV laser testing, UV spectroscopy and lithography optical experiments, excessive light intensity will lead to detector saturation, optical component damage and overexposed imaging.
