MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202611110636 A) filed by Indian Institute Of Technology Delhi on September 15, 2026, for A Low-Temperature Polarization-Resolved Raman Spectroscopy System With A Configurable Sample Space.
Inventors include Kaushik Sen; and Reshma Kumawat.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: A low-temperature, polarization-resolved Raman spectroscopy system (102) includes a polarization-control element (110), a Raman beam-routing assembly (116, 122, 130), an independently configurable sample space, one or more Rayleigh-suppression filters (114, 144), an analyzer (140), a spectrometer (150), and a detector (152). The Raman beam-routing assembly directs an excitation beam towards a sample (120) and collects Raman-scattered light substantially in a backscattering geometry. A sample-visualization assembly includes a white-light source (124), an optical fibre (126), visualization optics (128), a beam splitter (118), and a complementary metal- oxide-semiconductor camera (136) for illuminating, viewing, and aligning the sample (120). After sample visualization and alignment, at least the beam splitter (118) and one or more associated visualization components are removable from the Raman beam path using translatable mounts, thereby permitting Raman measurements without the visualization components in the beam path. The independently configurable sample space can accommodate a cryogenic or other specialized sample environment without reconstruction of the spectrometer-side optical train, thereby providing a modular platform for low-temperature, polarization-resolved Raman measurements. In an embodiment, reconfiguration is localized to the sample-space interface and objective-to-sample relationship while the downstream polarization- analysis, spatial-filtering, and spectral-detection portions remain substantially retained.
