UV ENHANCED SPECTROMETER

UV Spectrometer

 The UV Spectrometer employs a UV-enhanced 512-pixel linear CMOS sensor with UV response improved by up to 20 times, delivering exceptional sensitivity across the 200–1100 nm wavelength range. The CMOS sensor features an exposure time controllable down to 1 ms, enabling users to accurately optimize the signal-to-noise ratio (SNR) for precise spectral measurements.

Designed for high reliability, ultra-high-speed performance, and cost-effective operation, this UV Spectrometer is ideal for miniature spectrometer integration and a wide range of environmental monitoring and online testing applications. It is well suited for UV, visible, and near-infrared (NIR) spectroscopy.

A variety of slits, gratings, mirrors, and optical filters are available, allowing the spectrometer to be configured for different measurement requirements. It supports a spectral range from 200 nm to 1100 nm, with selectable spectral resolutions from 1.0 nm to 5.0 nm. Customized OEM configurations are also available to meet specific application needs.

The UV Spectrometer accepts optical input through an SMA905 optical fiber interface or via free-space optical input. Measurements are performed according to the selected integration time, and spectral data is transmitted through USB 2.0 (High-Speed) or UART interfaces for seamless integration into analytical and industrial systems.
