Microscopic Raman System —532/785 RAM3-785-500 Raman System
Shanghai Jiepu Technology's micro-Raman system uses a Hamamatsu 11639 CMOS detector for ultrahigh stability. Available as 532 and 785 systems, it combines highly sensitive detection and stable high-performance laser output for measured spectral stability >99%. Raman-shift range is 200 - 3000cm-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.

Fourier Spectrometer Fiber SMA-IRF-01 Spectrometers Fiberock
Optical fiber material: Infrared silica fiber Connector Type: SMA905/FC/custom Fiber core count: Single-core
Fourier-transform infrared (FTIR) spectrometers acquire material IR spectra using a transform from time/space to frequency domains, generally with high sensitivity and rapid acquisition. FTIR fibers deliver IR to samples difficult to access directly or return sample light to detectors. They allow flexible sampling of different regions or confined locations where the whole instrument cannot fit. Applications include chemistry, materials, biomedicine, and environmental monitoring. Fiber-linked instruments provide in-situ spectra under original sample conditions, valuable for live chemical-reaction/tissue studies. Selection: 1. Fiber type matches application/wavelength. 2. NA controls collection; higher NA gathers more signal but possibly more source background. 3. Diameter balances intensity/sensitivity and spatial resolution: larger gathers more but resolves less; smaller does the reverse. 4. Length balances loss and layout flexibility. 5. Bend resistance maintains stable transmission under bending/torsion. 6. Coatings/jackets match temperature, humidity, mechanical conditions, corrosion, and heat. 7. Connectors match instrument/probe interfaces for stable coupling. Balanced selection improves accuracy, sensitivity, and reliability.

A microlens array (MLA) is a high-precision optical component composed of hundreds or thousands of tiny, uniformly arranged micro lenses on a single flat substrate. Unlike traditional single lenses that focus one light beam, a microlens array can split, homogenize, and reshape light on a micro scale. It is widely paired with VCSELs, lasers, and image sensors, becoming a core part of modern miniature optical systems.
A laser bar is an array semiconductor laser chip integrated with dozens of emitters, which realizes hundred-watt quasi-continuous output on a single chip. With regular emitter arrangement and controllable fill factor, integrated thermal design and superior wall-plug efficiency compared to single chips, it acts as the core light source for high-power pumping, medical lasers and precision processing.
