VIS-NIR spectrometers for system integration
Choosing the right VIS-NIR spectrometer
VIS-NIR spectrometers are used to analyze samples in the visible and near-infrared spectral range (typically 500 – 1100 nm). VIS-NIR instruments utilize a light source and a spectrometer to measure the absorbance or emission of light by a sample. When selecting a VIS-NIR spectrometer, it is essential to consider specific application requirements, such as wavelength range, resolution, sensitivity, stray light performance and signal-to-noise ratio (SNR).
The resolution of the spectrometer determines its ability to distinguish between closely spaced spectral features, which is vital for accurate analysis. Sensitivity and stray light performance are also critical, as they affect the spectrometer's ability to detect low concentrations of analytes in a large dynamic range.
Our VIS-NIR spectrometers are designed to provide high sensitivity and resolution, making them ideal for many applications, including absorption and fluorescence spectroscopy. They feature advanced optics and low noise detectors and electronics to ensure precise measurements and can be easily integrated into OEM systems. Furthermore, our compact design and robust construction make them suitable for industrial environments.
The world’s best broadband gratings for VIS-NIR spectrometers
The high sensitivity of our visible light spectrometers is obtained through in-house manufactured transmission gratings.
Our VIS-NIR gratings offer the highest broadband efficiency on the market, enabled by optimized groove profiles, a thin optical path, and a high refractive index contrast. The inherent nature of fused silica ensures our gratings are environmentally stable while working in transmission, providing angle insensitivity and vibrational stability.
We design our VIS-NIR spectrometers to perfectly match and supplement the performance of our gratings, but we also supply gratings for use in your own VIS-NIR spectrometer design.
