◆SHG spectrum (standard function): SHG spectrum excited by point-focusing or wide-field. ◆SHG 2D Mapping (standard function): The laser is point-focusing on the sample, and the motorized stepping stages moves in two-dimensional space to realize the 2D Mapping function. ◆Motorized polarization-dependent spectrum and mapping (optional function): Polarization measurement can be realized by synchronous rotation of the polarizer and analyzer, or only rotation of the polarizer (analyzer).
it is used for imaging biological tissues such as proteins, genomic DNA, cells and nuclear extracts. it is used to detect the lesions of mucosal tissues, in vivo monitoring of drug permeability, dental imaging, etc. it is used to characterize the emission characteristics, crystal type and orientation, anisotropy, and the polarization of ferroelectric materials.
