Work Detail

Laboratory, Optical And Precision Equipments (Excl. Glasses) – Acquisition Of A Microscope In The Digitall Project. 1 New Two-Photon Microscope, With The Following Minimum Technical Parameters: In Materials Science And Biology Samples, With Low-Energy Excitation, Using The Local Light Emission Of The Objects To Be Examined, The Equipment Is Capable Of Complete Imaging With A Micrometer Resolution And A Range Of 1 Mm2. Special Two-Photon Excitation Is Achieved With The Help Of The High Intensity Of The Laser Excitation And Its Low-Energy Photons. Adequate Space And Time Resolution Of The Emission Following Two-Photon Excitation Results In A 3D Image With Adequate Resolution. 1. New Device 2.
