An electrostatic discharge generator is a device used to simulate and test the tolerance of electronic devices and systems to electrostatic discharge (ESD) environments. By simulating the amplitude, frequency, and waveform of electrostatic discharges, it can replicate ESD events in real-world environments to validate the durability and performance of equipment. Components of an Electrostatic Disch...
Dielectric strength testing assesses the ability of electrical devices, insulation materials, and insulation structures to withstand high voltages. Its primary objective is to check whether insulation can withstand operating voltages or overvoltages without compromising its performance, ensuring that the insulation performance of equipment meets safety standards. Basic Principles of Dielectric Str...
Introduction: An integrating sphere, also known as a photometric sphere or luminous sphere, is a hollow spherical device used for optical measurements. Its design incorporates one or more ports on the sphere’s surface for light input and placement of light-receiving devices. Structure and Characteristics of Integrating Spheres: Sphere Shell and Deviation Requirements: • An integrating sph...
The electrostatic discharge generator is a specialized device utilized to simulate and assess the resilience of electronic devices under electrostatic discharge (ESD) and similar electrostatically related environments. It validates the performance and durability of devices by mimicking the amplitude, frequency, and waveform of electrostatic discharges. The generator primarily consists of a power s...
Distributed photometers are essential measurement devices used to test the photometric performance of lighting fixtures. They are categorized into vertical and horizontal types and are capable of measuring parameters such as spatial light intensity distribution, total luminous flux, and luminaire efficiency. The system comprises precision turntables and control systems, spectral analysis systems, ...
The RoHS tester is an instrument used to detect the presence of hazardous substances restricted by the EU RoHS standard, primarily detecting six harmful substances including lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr6+), polybrominated diphenyl ethers (PBDE), and polybrominated biphenyls (PBB). The RoHS tester typically refers to an X-ray fluorescence spectrometer, with an anal...
With the continuous development of technology and the improvement of people’s living standards, electronic products and mechanical equipment have become an indispensable part of daily life. However, in a constantly changing environment, the issues of waterproofing and dustproofing faced by products are increasingly prominent. In order to ensure that products can function properly under vario...
Dust penetration into products can have significant impacts on their performance and durability: • Breaching Seals and Casings:Dust can infiltrate internal spaces through seals and casings, compromising sealing effectiveness and thereby affecting waterproofing and environmental adaptability. • Altered Electrical Performance: Dust particles can affect electrical performance by increasing contac...
Light-mediated biological effects refer to the physiological changes in the human body caused by exposure to light radiation. The mechanism of light-mediated biological effects varies depending on different pathways. Firstly, light can directly act on the human eye, transmitting visual information and inducing visual effects. Secondly, light can regulate the body’s physiological rhythms by a...
