Two-photon laser scanning confocal microscope

Two-photon laser confocal microscopy utilizes long-wavelength lasers to excite the sample, where two-photon absorption causes fluorescent molecules to emit light in the focal region. Stray light is eliminated through a confocal pinhole. This technique is used to observe the three-dimensional structure of thick samples, reducing photodamage in biological tissue imaging and material detection.
Selection
When selecting, consider matching the laser wavelength to the sample's absorption characteristics, ensuring the detector's sensitivity is suitable for the fluorescence signal intensity, and that the scanning speed meets the requirements for dynamic observation. Determine the working distance of the objective lens based on the sample thickness, and compare system maintenance costs and imaging stability within the budget.
