UV-VIS spectrometers for system integration
Choosing the right UV-VIS spectrometer for your application
UV-VIS spectrometers are important for analyzing samples in the ultraviolet, visible and near-infrared spectrum (typically 200-1100 nm). UV-VIS instruments utilize a light source and a spectrometer to measure the absorbance or emission of light by a sample. When selecting a UV-VIS spectrometer, it is essential to consider 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 is also critical, as it affects the spectrometer's ability to detect concentrations of analytes within a large linear dynamic range.
Our UV-VIS spectrometers provide high broadband sensitivity and resolution, making them ideal for many applications including absorbance spectroscopy, HPLC UV-detectors and optical thin film measurements. They feature our unique UV-VIS transmission gratings with flat spectral response and high dispersion. Our compact spectrometer design and robust construction make them suitable for industrial environments, and low unit-to-unit variation enables seamless integration into OEM systems

Unique high-dispersion and broadband gratings for UV-VIS spectrometers
Our UV-VIS spectrometers are more compact than any other UV-VIS spectrometer on the market due to our in-house manufactured broadband transmission gratings.
Our gratings provide almost flat spectral response over the entire UV-VIS range, enabled by optimized groove profiles, a thin optical path, and a high refractive index contrast. Furthermore, the gratings have a high groove density which lead to extremely compact modules. The inherent nature of fused silica ensures environmentally stable operation.
We design our UV-VIS spectrometers to perfectly match and supplement the performance of our gratings, but we also supply gratings for use in your own UV-VIS spectrometer design.
