Cell differentiation based on absorption and scattering. [PDF]

Journal of Histochemistry & Cytochemistry, 1979
Improvements of the flow system allow calibrated cell length measurements down to less than 2 micron at a very high rate. An optical index match to plane viewing windows perpendicular to the optical axis in the flow system keeps the axial symmetry for forward scattered light.

3D Printed Modular Vein Viewing System Based on Differential Light Absorption in the Near Infrared Range

Journal of Biomedical Photonics & Engineering, 2023
There are many cases in the medical laboratory examinations when it is necessary to detect a vein in a patient and the blood vessels are not visible to the naked eye. In such situations, devices for optical vein visualization are required.
