ATP2000 High SNR Spectrometer Sensor

The spectrometer sensor separates or disperses polychromatic light in space according to different wavelengths, in combination with a detector, to obtain information such as wavelength components and the intensity of each wavelength component. Typically, optical fibers are used as signal coupling devices to couple the measured light into the spectrometer for spectral analysis.

The performance of the spectrometer sensor is primarily determined by its core components, and different component specifications can lead to differences in the overall performance of the spectrometer.

01Product Introduction
ATP2000 spectrometer sensor is a versatile, high signal-to-noise ratio product model launched by Optosky. It features a cross-type C-T optical path design, which is compact in structure and offers high sensitivity. Additionally, it is equipped with a UV-enhanced linear array CMOS sensor with 2048 or 4096 pixels, capable of testing in the wavelength range of 190-1100 nm, with the shortest exposure time reaching 0.2 ms. Furthermore, Optosky has incorporated a filter within the spectrometer to eliminate higher-order diffraction, preventing interference.

ATP2000 offers a range of derivative models for customers to choose from, catering to various complex application scenarios. Among them, the ATP2000P is the general-purpose UV-enhanced model, while the high-speed versions ATP2000H/SH and the xenon lamp-integrated version ATP2002 are also available.
