Visible light (VIS) spectrometers
Choosing the right VIS spectrometer
VIS spectrometers are used to analyze samples in the visible spectrum (typically 400-700 nm). VIS instruments utilize a light source and a spectrometer to measure the absorbance or emission of light by a sample or to characterize the spectral emission of the light source itself. When selecting a VIS spectrometer, you need to consider 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 visible light with high linearity in a large dynamic range.
Our VIS spectrometers are designed to provide high throughput and resolution, making them ideal for many applications, including absorption and fluorescence spectroscopy as well as color measurements and light source spectral characterization. Other common applications include material characterization and environmental monitoring.
Since our VIS spectrometers feature advanced optics and low noise detectors and electronics to ensure precise measurements, they can be easily integrated into OEM systems. Furthermore, our compact design and robust construction make them suitable for industrial environments. In industrial settings, our high throughput VIS spectrometers play an important role in quality control (QC) and process control (PAT), enabling real-time monitoring and optimization of production workflows.
The world’s best broadband gratings for VIS spectrometers
The high sensitivity of our VIS spectrometers is achieved with our in-house manufactured transmission gratings.
Our VIS gratings provide high and even broadband efficiency and high dispersion, 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 thermally stable. Working in transmission provides angle insensitivity and vibrational stability.
We design our VIS spectrometers to perfectly match and supplement the performance of our gratings, but we also supply gratings for use in your own VIS spectrometer design.
