LIMA™ is a hyperspectral microscope based on a widely tunable laser source. It uses Photon etc.’s filtering technology to illuminate the full field of view of a research-grade microscope with a continuously tunable monochromatic, high power density laser light. The system provides a high spectral resolution in the VIS, NIR, and SWIR combined to a near-diffraction-limited spatial resolution. Ideal for darkfield, PLE, or standard brightfield reflectance and transmittance imaging, it can map the full spectral response of a sample much faster than point-by-point or line-scan-based systems.
