DEVICE FOR THE REAL-TIME OBSERVATION OF THE EVOLUTION OF MACROSCOPIC BIOLOGICAL MATERIAL IN VITRO

摘要

The invention relates to a photographic device for the real-time observation of the evolution of macroscopic biological material in a sealed Petri dish (4). According to the invention, the device consists of two identical parts, each part containing: a digital photographic camera (1) mounted horizontally on a support (2) provided at the bottom with an optical mirror (3) positioned at 45°, a Petri dish (4) which contains the biological material (41) to be analyzed, placed on a horizontal support (5) above the lens of the photographic camera (1) and a LED matrix lamp (6), transparent to electromagnetic field, provided with a diffusion system (61), positioned above the Petri dish (4) such that the optical path (7) of the whole assembly passes through the center of the lens of the photographic camera (1), the center of the Petri dish (4) and the center of the lamp (6), where the photographic camera (1) and the lamp (6) are supplied from an uninterruptible low-voltage source (8), with two separate outputs (81, 82).
