Quantitative phase microscopy

Quantitative phase microscopy (QPM) is an emerging label-free imaging method. The QPM technology measures the phase delay of the transmitted or reflected light of the measured microscopic object, and in the absence of marker staining, the resulting image can provide objective morphological and dynamic results.

In the past two decades, QPM technology has made tremendous progress, and has been applied in many different fields. Especially in the field of biomedicine, QPM technology is more and more popular with scientific research and clinical experts.

Unparalleled advantages

Quantitative phase microscopy (QPM) technology is an important method for biomedical analysis and thin film material detection, with no chemical marking, high precision, portable and compact, fast, low cost Features.

  • Measure the refractive index distribution and topography
  • Without marking, use the intrinsic contrast of organisms
  • Can image for a long time and observe the change of sample cycle
  • Full scan, three-dimensional tomography
  • Fast imaging speed, convenient for dynamics research
  • No damage to the observation body, more suitable for clinical research
  • Modular design, can be combined with other imaging technologies to achieve multi-function

More dimensions, greater depth

Traditional imaging methods use changes in light wavelength and intensity to transform the sensor into colors and gray levels that can be recognized by the sensor to achieve image contrast, which allows you to distinguish the observed object from the background.

QPM technology captures and analyzes the third important data of light: phase information. The phase information is very important. By transforming it into a refractive index profile, it can fully display the shape and properties of the material, and then further transform it into information such as size and density, which can perfectly achieve fine quantitative analysis of microscopic materials and transparent samples.
