High-rejection BIPD filter
Brillouin spectroscopy faces challenging detection capability due to strong and unavoidable elastic background light arising from specular reflections and Rayleigh scattering. This background typically overcomes the weak Brillouin peaks, limiting the spectral investigation to samples that are mostly semi-transparent.
Our proprietary Birefringent-Induced Phase Delay (BIPD) filter provides a simple and effective solution to suppress extremely high levels of elastic background light to enable the acquisition of the Brillouin light spectrum. Being common-path and ultra-compact, our BIPD filter offers flexible implementation in standard optical setups spanning from spontaneous to stimulated Brillouin microscopes. Notably, the BIPD filter can be tuned in a fraction of second at any desired laser frequency with possibility to operate across a broad range of VIS and NIR wavelengths. The ultra-high rejection capability and robust design features make the BIPD filter an ideal choice to perform Brillouin spectroscopy even in extremely turbid samples.

APPLICATIONS
Brillouin spectroscopy
LOW-FREQUENCY RAMAN SPECTROSCOPY
Brillouin spectroscopy is an all-optical elastography method used to explore the mechanical properties of materials by probing their acoustic phonons. It provides precise information about elastic moduli, viscosity, and phase transitions at microscopic scales. The non-destructive and label-free features make this method ideal to investigate viscoelastic properties in the volume of living biological systems.
Low-frequency Raman THz spectroscopy provides detailed insights into the molecular structure and material dynamics. By analyzing the vibrational modes in the terahertz range, this technique enables the investigation of low-frequency phonon modes and intermolecular interactions. It is particularly valuable in pharmaceuticals and material science, where understanding molecular interactions and polymorphism is a crucial requirement.
Specto’s BIPD filter unleashes the full potential of Brillouin spectroscopy, providing the opportunity to investigate turbid media that are still poorly characterized. The ultra-high extinction enables 3D mechanical imaging using single-stage spectrometers.
Specto’s BIPD filter extends the capability of standard Raman spectrometers with minimal effort and across a broad range of wavelengths, providing the opportunity to acquire Raman THz spectra in the low frequency region.
