VIS-NIR spectrometers for system integration
Choosing the right VIS-NIR spectrometer
VIS-NIR spectrometers are crucial tools for analyzing samples in the visible and near infrared spectrum (typicall 500 – 1100 nm). These 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 the specific application requirements, such as wavelength range, resolution, sensitivity, and stray light performance.
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 diverse applications, including absorption and fluorescence spectroscopy. They feature advanced optics 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.

Best in class broadband gratings for VIS-NIR spectrometers
The high sensitivity of our visible light spectrometers is obtained through in-house manufactured transmission gratings.
Our gratings provide unparalleled high broadband efficiency, 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 visible light 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.
