NIR spectrometers for system integration

Choosing the right NIR spectrometer for your application

NIR spectrometers are crucial tools for analyzing samples in the near infrared spectrum (typically 900 – 2100 nm). NIR instruments utilize a light source and a spectrometer to measure the absorbance or emission of light by a sample. When selecting a 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 NIR spectrometers are designed to provide high sensitivity and resolution, making them ideal for diverse applications, including absorption 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 NIR spectrometers

The high sensitivity of our NIR 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 NIR spectrometer design.
