Low Noise Absorbance Measurement System

Low Noise Absorbance
Low Noise Absorbance Measurement System
1 unit
Made in China
Take advantage of Optosky application-ready systems – spectrometer, light source, accessories and software – for absorbance measurements.
ATX2000 is a high-performance, low-noise absorbance and fluorescence measurement system developed by Optosky. The system is completely independently developed by Optosky Photonics Ltd. Among them, the low-noise optical fiber spectrometer adopts optimized optical and electronic design, which greatly reduces the noise of the sensor, obtains an excellent signal-to-noise ratio (about 5 times higher than that of similar competitors), and improves the The measurement reliability of ATX2000, the measurement results do not change with the ambient temperature.
The ATX2000 can be easily configured to measure and study various spectra such as reflection, transmission, absorption, and fluorescence.
The ATX2000 adopts a pulsed xenon lamp (wavelength range 190-1100nm) with a lifespan of 109 flashes, which can be used for more than 5 years without changing the light source.
ATX2000 only needs a 5V DC power supply, plus a computer, it can work, very simple and easy to use.

ATX2000 spectral measurement system usually includes spectrometer, light source, optical fiber, sample holder, standard reference sample, and software, etc. The components of each part are as follows:
  1. Low noise fiber optic spectrometer;
  2. Long-life pulsed xenon lamp, broad-spectrum ultraviolet, visible and near-infrared light sources;
  3. Spectrometer, pulse xenon lamp synchronous control circuit board;
  4. High transmittance UV fiber;
  5. Integrated multi-function measurement sample cell for transmission, reflection and fluorescence;
  6. Optosky_Spectral professional spectral measurement software.
Each constituent spectral part has its spectral range. Therefore, it is necessary to select an appropriate spectral range according to the actual needs of users. For example, in order to measure the spectrum of the ultraviolet part, it is necessary to use a UV-sensitized spectrometer or an area-array back-illuminated spectrometer capable of detecting the ultraviolet band, and a broad-spectrum light source with ultraviolet radiation.
