785/532 Online Raman System RAM3-532-200
Shanghai Jiepu Technology's RAM3 Raman system uses a Hamamatsu CMOS detector for ultrahigh stability. Available as 532 and 785 Raman systems, it combines a highly sensitive detector and stable high-performance laser output, achieving measured spectral stability >99%. Raman-shift range is 200 - 3200cm-1, providing a cost-effective, highly stable solution. Light scattered by matter includes elastic components at the excitation wavelength and inelastic components at longer and shorter wavelengths, collectively described as the Raman effect. It results from interaction of photons with optical-branch phonons. Principle: Molecular and lattice vibrations and rotations give rise to Raman spectra, revealing vibrational and rotational energy-level structure. Virtual upper energy levels explain the effect.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
The 850 nm and 940 nm infrared narrow‑bandpass filters launched by Innovation Photoelectric are core optical components specially designed for day‑and‑night security cameras. They effectively eliminate image interference during visible‑light and infrared‑illumination switching, delivering stable round‑the‑clock monitoring performance.
Within cutting‑edge ultrafast photonics research, asynchronous optical sampling (ASOPS) and synchronous sampling serve as fundamental technologies for terahertz excitation detection, coherent Raman imaging and other time‑resolved spectroscopy experiments.
