Dimension-Labs offers a series of fiber spectrometers covering the spectral range of 190-2500nm, including ultraviolet, visible light and near-infrared wavelengths. There are six series of spectrometers, namely general-purpose, high resolution, high sensitivity, refrigeration, deep refrigeration and near-infrared (see the table below for more details). Its performance parameter series covers teaching, industrial and scientific research levels, and is suitable for different application environments such as laboratories, scientific research and industrial sites.
The spectrometer can perform high-precision spectral analysis of the structure and components of matter. Use dispersion principle, diffraction principle, or optical modulation principle to decompose optical radiation at different frequencies according to certain rules to form a spectrum. Combined with a series of optical, precision mechanical, electronic and computer systems, we can achieve the purpose of precise measurement and research on the frequency and intensity of optical radiation. The small fiber spectrometer adopts folding optical path, fiber conduction, array detector and other technologies. It is small in size, fast in detection and easy to use, and is very suitable for online, in-situ, portable and other applications.

component
The main components of a fiber optic spectrometer include slits, gratings, and detectors (as shown in Figures 2, 4, and 6). The performance of a spectrometer depends on the selection, precise combination, and calibration of these components.

- SMA905 fiber optic interface: The signal beam is transmitted through a standard fiber optic cable, coupled through the fiber optic interface, and enters the spectrometer
- Incident slit: Before entering the spectrometer, the signal beam must pass through the incident slit, and only an appropriate amount of light signal is allowed to enter the spectrometer. The size of the incident slit will affect the resolution and sensitivity parameters of the spectrometer.
- Collimator element: turns the light emitted by the slit into parallel light.
- Grating: disperses optical signals into multiple beams of light according to wavelength in space. Grating divides incident light and is the core component that affects the main performance of the spectrometer, determining the spectral range and resolution of the spectrometer.
- Focusing element: Focus the well split light beam onto the photosensitive area of the detector.
- Detector array: converts the light signals collected in the photosensitive area into electrical signals and sends them to the processing system for processing. There are two types of detectors for fiber optic spectrometers: wired array and surface array.
Main Applications
- Transmission, reflection, and laser center wavelength measurement
- Light color measurement
- Radiometric measurement
- Water quality and smoke detection
- laser-induced fluorescence
- Semiconductor/Plastic Manufacturing - Film Thickness Measurement
