Photothermal Spectroscopy Corp. has released the stRAMos, a new Raman microscope that utilizes photothermal detection of stimulated Raman scattering. The system is designed to provide high-resolution imaging for both materials science and life science research applications.
Why it matters
By integrating multimodal imaging capabilities, the platform aims to provide researchers with increased sensitivity and spatial resolution. The system addresses long-standing trade-offs in speed and imaging clarity within specialized microscopic analysis.
The stRAMos system achieves a spatial resolution of 300 nm or less and features laser tuning speeds of 25 ms per wavenumber. These performance figures represent a 10x sensitivity improvement compared to conventional SRS techniques.
The players
Photothermal Spectroscopy Corp.
A developer of specialized optical microscopy hardware focusing on photothermal detection and chemical imaging for laboratory use.
The details
The stRAMos utilizes PhotoThermalSRS, a process that detects the photothermal signals generated during stimulated Raman scattering — a non-linear optical process that uses two synchronized laser beams to probe molecular vibrations. This allows for multimodal imaging by integrating the technique with O-PTIR (Optical Photothermal Infrared spectroscopy), fluorescence microscopy, and conventional spontaneous Raman spectroscopy. By combining these methods, the system provides high-contrast chemical imaging with precise spatial resolution.
Timeline

The Tech Race
The stRAMos represents the commercialization of the PT-SRS technique originating from the research labs at Boston University. This launch moves the technology from experimental laboratory demonstrations into a platform intended to compete with established high-speed confocal Raman systems.
Researchers in the life sciences and materials fields can now incorporate this multimodal imaging into their existing workflows to replace slower, conventional Raman methods. The system serves as a specialized tool for labs requiring rapid, high-resolution chemical analysis on a microscopic scale.
The takeaway
The stRAMos platform attempts to bridge the gap between high-resolution spatial imaging and the high speeds required for complex molecular research. Interested parties should watch for upcoming technical documentation or peer-reviewed case studies that validate these sensitivity figures in real-world samples.
