1550nmDTS pulsed light source
The Shanghai Hanyu 1550nm modular pulsed light source is a high-efficiency pulsed light source based on eye-safe wavelengths, adopting a master oscillator power amplifier (MOPA) structure design, using a high-performance narrow-linewidth DFB (external cavity) semiconductor laser as the seed source with a built-in signal generator. Through optimized multi-stage optical amplification, it achieves high peak power, ns-level pulse width laser output, very suitable for DTS distributed temperature measurement systems, fiber sensing, LiDAR and many other fields.

Sunday-optics
Enclosure material: Aluminum or Copper Optical element: Aspheric lenses, two-element lenses, three-element lenses (glass), single rubber rings, and two-piece rubber rings Dimensions: M6X0.5、M7X0.5、M9X0.5、M8X0.5、M12.7X0.5
A collimating lens converts light from each point in an aperture column into a parallel, collimated beam. Lens selection depends on aberration requirements. Simple plano-convex or biconvex lenses with larger relative apertures suit low demands; achromats with smaller relative apertures suit higher demands. Collimators are a key Sunday product, available as standard or custom designs. Sandi Optoelectronics offers single aspheres, doublets and triplets.

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.
