Collinear Ultrafast Spectrometer
The BIGFOOT spectrometer by MONSTR Sense Technologies is a multi-functional tool for state-of-the-art optical measurements. We combine the most advanced ultrafast measurements of vibrational and electronic sample properties into a single device: transient absorption, coherent Raman, and multidimensional spectroscopies. The spectrometer will also perform linear absorption spectroscopy to accompany the more advanced methods. Our spectrometer is very easy to use with a one-time alignment of a laser into the device and intuitive LabVIEW based software.
Many spectroscopic techniques
Research is never easy, but your equipment should not limit you. Get the most out of your sample with the best resonant and non-resonant ultrafast spectroscopy techniques. One BIGFOOT collinear spectrometer is capable of all of the following:
Our transient absorption spectrometer is the only fully-collinear technique capable of resonant pumping. Measure ultrafast dynamics of resonantly excited transitions without convolving or dephasing the dynamics you care about with non-resonantly excited states. You may also spectrally resolve either the emission or the excitation using the built-in Fourier-transform spectroscopy. Spectrally-resolved transient absorption is useful for identifying multiple sources of decay in features with different spectral signatures.
Coherent Raman Spectroscopy (CRS)
Also called impulsed stimulated Raman (ISRS), the MONSTR Sense spectrometer is capable of measuring both ground and excited state vibrational resonances. When applied to imaging biological samples, it is often called label-free imaging. Coherent Raman spectroscopy enhances Raman signals by up to nine orders of magnitude, and so our spectrometer is a great tool for rapid measurement of dense samples.
MDCS is the spectroscopy for completely measuring the third order nonlinear optical response of a material. The BIGFOOT collinear spectrometer was originally developed for MDCS, and it allows you to use a variety of pulse sequences to completely characterize inhomogeneous samples and coupling.
