Raman spectroscopy is an analytical technique based on the Raman scattering effect. It provides detailed information about the chemical structure, phases and morphology, crystallinity, and molecular interactions of a sample.

Night vision lighting inspection utilizes near-infrared technology for nighttime monitoring. Dazzling lighting is typically used for long-distance warnings in special environments. White light illumination, with its high efficiency and environmentally friendly characteristics, is widely used in the automotive and display industries. The laser rail transportation detection system precisely calculates the geometric parameters of the track by analyzing the laser signals reflected from the track surface, ensuring safe and stable operation. Caplin's various solutions are widely applicable to different lighting inspection environments.
