Dual-frequency comb spectroscopy permits broadband precision spectroscopic measurements with short acquisition time. A dramatic improvement of the maximal spectral bandwidth and the minimal measurement time can be expected when the lasers’ pulse repetition rate is increased, owing to a quadratic dependence (Nyquist criterion). This white paper demonstrates a dual-comb system operating at a high repetition rate of 1 GHz based on mature, digitally-controlled, low-noise modelocked lasers
Wavelength Electronics’ LFI3751 temperature controller provided the precision to support a new biosensor developed in Spain and based on the oxygen-dependent degradation domain of HIF-1α. The biosensor provides critical information about the size and location of in vivo tumors, as well as their micro-environment. The LFI maintained the narrow linewidth and stable wavelength necessary for fluorescence spectroscopy with integration times of 0.5 seconds and measurement increments of 1nm.

A gamma ray and neutron spectrometer was recently installed on the ‘Psyche’ spacecraft, which will launch next year to probe a distant asteroid and uncover clues about the origins of our solar system
Pro-Lite’s Robert Yeo reviews the science of integrating spheres and explains how they are used in reflectance spectroscopy.
The GEMINI interferometer enables an innovative approach to broadband pump-probe spectroscopy. Thanks to the employed time-domain Fourier Transform (FT) detection system, this configuration permits the measurement of the broadband pump-probe signal with a single-pixel detector and a single-channel lock in amplifier. In this way, it's possible to combine an ultra-broad spectral coverage with an extremely high sensitivity
Raman spectroscopy is powerful and versatile analytical tool that is applied in a vast array of applications from materials science to medical diagnostics. In this white paper, Pro-Lite explains how a new class of spectrometers developed by Wasatch Photonics results in compact Raman spectrometers far faster and more sensitive than typical compact spectrometers.
