NIR spectrometers

Need fast, sensitive NIR measurements? Wasatch Photonics line of high throughput modular NIRspectrometers deliver the best price to performance on the market. Sensitivity, speed and LOD are key.

The greatest challenge in compact NIR spectroscopy is collecting enough signal to achieve adequate SNR (signal to noise ratio). With many spectrometers on the market, it’s hard to know which has the performance needed. Here, Wasatch Photonics benchmarks the superior sensitivity, data quality, and reliability of our NIR spectrometers.

InGaAs diode array spectrometers are often light-starved, and require cooling of the detector to reduce thermal noise to an acceptable level. Increasing the acquisition time boosts signal, but results in more noise and compromises the practical speed at which measurements can be made. Using a better spectrometer is a simpler solution that improves spectral quality, LOD, and facilitates more accurate chemometric analysis.

When Wasatch Photonics created the WP 1064 for Raman and broadband WP NIR, they boosted sensitivity in every aspect of the design, supported by the robust, thermally stable mechanics we know our OEMs need. With their own design highly efficient volume phase holographic (VPH) gratings in a diffraction-limited transmissive design, these products deliver high quality NIR data in 1/10th the time of a typical cooled f/4 crossed Czerny-Turner (CCT) NIR spectrometer, and far more reliably.

Wasatch Photonics has maximized the efficiency of their spectrometers to give you more sensitivity, better SNR, and faster measurements. Collect more light with our f/1.3 input, keep more light with our high transmission VPH gratings & diffraction-limited optics, and detect more light with scientific-grade detectors. Our build-to-print options for resolution and sample coupling allow you to configure a spectrometer or system with the exact performance you need. The configuration options for our build-to-print NIR spectrometers include slit size (resolution) and sample coupling (fiber coupled or free space). We use only high sensitivity TEC cooled detectors to ensure the best possible signal to noise (SNR) and spectral reproducibility at the shortest acquisition times.

Collect More Light. Keep More Light. Detect More Light - This may sound simple, but it’s the driving force behind all Wasatch does – because it makes for good spectroscopy. Starting with the proprietary volume phase holographic (VPH) gratings on which the company was founded, we’ve designed a spectrometer that maximizes efficiency at every step. By keeping more light in the optical path, we reduce stray light within the bench, thus increasing signal while reducing noise. Wasatch Photonics has designed high NA (low f/#) spectrometer input, which captures more light from the sample. Our user-configurable probes have been designed to match, and come with compatible fibers to maximize light collection.
