The LIMA global hyperspectral microscope uses excitation based on a widely tunable excitation source spanning 400 nm to 1620 nm, allowing for unique darkfield and brightfield imaging.
The LIMA global hyperspectral microscope uses excitation based on a widely tunable excitation source spanning 400 nm to 1620 nm, allowing for unique darkfield and brightfield imaging.
Photon etc.’s filtering technology illuminates 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.
Three models of the LIMA are available all offer sub micron spatial resolution over the spectral range of operation.
The available models are:
LIMA VIS 400-1000nm, 1.5 – 2.5 nm spectral resolution. Detection via sCMOS (optionally EMCCD or CCD)
LIMA SWIR 900-1620 nm, 3.0 – 5.0 nm spectral resolution. Detection is via Photon etc. InGaAs camera (ZephIR 1.7 or Alizé 1.7)
LIMA eSWIR 1000-2500 nm, <5.0 nm spectral resolution. Detection is via Photon etc. HgCdTe camera ZephIR 2.7
