mK-CONFOCAL/RAMAN MICROSCOPE (mK-CFM/RAMAN) | Low Temperature Microscope

mK-Confocal/Raman Microscope (mK-CFM/Raman)

Advanced Quantum Imaging at the Thermal Limit

The NanoMagnetics Instruments mK-CFM/Raman is a premier confocal and Raman microscopy platform designed for operation at the extreme frontier of low-temperature physics. Specifically optimized for integration into dilution refrigerators and high-field magnets, it enables the high-resolution study of quantum materials, 2D systems, and spin textures at temperatures as low as 10 mK and in magnetic fields up to 31 Tesla.

High-Performance Apochromatic Optics for Extreme Conditions

At the core of the system is our proprietary low-temperature apochromatic (APO) objective. Featuring a high numerical aperture of 0.82 and a 0.95 mm working distance, it provides exceptional light collection efficiency and diffraction-limited spatial resolution. The APO correction ensures that focal spots for excitation and Raman scattering are perfectly aligned across a broad spectral range (UV to NIR), eliminating the need for mechanical refocusing during multi-wavelength experiments.

Seamless Multimodal Confocal and Raman Capability

The mK-CFM/Raman architecture allows for simultaneous high-resolution confocal reflectance imaging and ultra-sensitive Raman spectroscopy. This multimodal approach empowers researchers to correlate topographical or structural features with local chemical and vibrational data in real-time. The system is engineered for maximum flexibility, offering full compatibility with industry-leading spectrometers and CCD cameras via high-efficiency fiber-optic coupling.
