LIBSsystem

The LIBS system (Laser Induced Breakdown Spectroscopy) integrates miniature and high peak power small lasers, allowing for real-time qualitative analysis of elements in the field. The suitcase like size, excellent seismic resistance, and good temperature stability of this LIBS system make the entire system very convenient for field operations. The system can be powered by batteries or DC power. By focusing with a 1064nm Nd: YAG laser (peak power reaching MW level) and hitting the target object, plasma is generated. During the process of plasma cooling annihilation, activated atoms in the plasma beam emit characteristic spectra related to the elements. The emission spectra of general elements are in the wavelength range of 200-980nm. Through the Spectral ID element luminescence spectrum database provided by SlarNet, the system can directly provide various elements corresponding to spectral lines. The advantage of LIBS system is that it does not require any sample preparation and the testing time is very short (usually within one second).

Chemical measurement system

ChemWiz-2000It is a practical chemical spectrometer that can be used for component analysis, concentration analysis, and substance identification of various substances.Many substances have specific absorption peaks or bands, and as long as we measure the absorption curve of the substance, we can conduct a series of analyses on it, such as its composition and content. ChemWiz-2000 can also achieve real-time monitoring in many production processes.

Radiometric measurement

The system is mainly used to measure the radiance distribution of various wavelengths of luminescent materials. Radiometric spectrometers can be used to measure the light intensity of LEDs, xy chromaticity （CIE 1931）， Purity, main wavelength, etc. The spectrometer needs to be used in conjunction with a cosine receptor or integrating sphere. SlarNet undergoes calibration with NIST (National Institute of Standards and Technology) standard light sources before leaving the factory to ensure the accuracy of measurement results. In addition, SlarNet also provides radiometric correction light sources for customers to calibrate themselves.

Thin film measurement

In the field of thin film measurement, spectrometers are widely used. Thin film thickness measurement is based on the principle of white light interference to determine the thickness of optical thin films. The white light interference pattern calculates the film thickness through mathematical functions. For single-layer films, if the n and k values of the thin film medium are known, its physical thickness can be calculated.

SlarNetWe can provide low-cost thin film measurement systems. Can detect multi-layer structures, single-layer, rough, and uneven thickness samples. Measure the film thickness range of 50A-20um with an accuracy of 0.2% or 10A

Fluorescence spectroscopy measurement

For fluorescence spectroscopy measurement, SlarNet provides three spectrometer configurations: 350-1000nm, 200-850nm, and 250-900nm. After being irradiated with excitation light within a specific spectral range, the sample produces fluorescence with longer wavelengths. Users can detect fluorescence through special sample pools or fiber optic probes. The spectrum is transmitted from a 1000um optical fiber to the spectrometer. If needed, we can also provide various multi-channel spectrometer configurations.

The commonly used excitation light source is the 470nm blue LED light (SL1-BUE), which has a linewidth of 30nm, only requires a driving current of 20mA, and is very cheap. In addition, using a pulsed xenon lamp (SL4-XENON) in conjunction with a filter can provide higher intensity excitation light. The deuterium lamp (SL3-DEUT) provided by SlarNet can provide a high-power continuous excitation light source. The system provides two interfaces: IEEE1248 and USB-2.0. The spectrometer has a driving current of 5V and the system is equipped with an AC to DC transformer.

color measurement

SlarNetMicro spectrometers can measure and compare the color of various samples, and the color of solid samples can be measured through fiber optic reflection probes; The color of liquids can be measured using an immersion fiber optic probe and a transmission tube.The system comes with powerful SpectraWiz, and this software is * free! For color measurement, the SpectraWiz system provides standard CIE 1976 L * a * b * (CIELAB) color space data. L * represents the brightness of the color. A positive a * value represents red, and a negative a * value represents green. Similarly, positive b * values represent yellow, and negative b * values represent blue. The L * a * b * value can be derived from the CIE tristimulus values X, Y, Z of the sample (object) and the tristimulus values Xn, Yn, Zn of the standard light source.
For colorimetric measurement, it is necessary to first test a standard sample and save its spectrum. Then the system can calculate Δ E based on the spectral difference between the measured sample and the standard sample, which is used to characterize the color difference between the two samples. For color monitoring processes that require multiple beams of light, SlarNet can also provide corresponding multi-channel spectrometers.
