Biological microscope illuminating system based on engineering diffuser

Abstract

The invention relates to the technical field of microscopes and provides a biological microscope illuminating system based on an engineering diffuser. The uniformity of lighting illuminance of an object table is improved, and the service life of the illuminating system is prolonged. Meanwhile, the structure of the illuminating system is simplified. According to the technical scheme, the biological microscope illuminating system based on the engineering diffuser comprises a light-emitting diode LED (1), a converging lens (2), the engineering diffuser (3) and the object table (4). The LED (1) provides high-intensity illuminating light beams. The converging lens (2) receives and converges the illuminating light beams. The engineering diffuser (3) controls the illuminating light beams to control the spatial distribution and the intensity outline of the illuminating light beams so that the illuminance of the illuminating light beams can be uniformly projected on biological samples which are placed on the object table (4) and are to be detected. The illuminating system is mainly applied to design and manufacture of microscope illuminating devices.

Description

technical field [0001] The invention relates to the technical field of microscopy; in particular, it relates to a biological microscope illumination system based on an engineering diffuser. technical background [0002] In the field of biological microscope technology, there are high requirements for the design of the lighting system, not only to meet the requirements of a larger lighting range and higher lighting intensity, but also to meet the requirements of uniform illumination. Specifically, for a biological microscope with a low-magnification objective lens, the requirement for illumination intensity is not high, but a larger illumination range and higher illumination uniformity are required; for a biological microscope with a high-magnification objective lens, higher illumination intensity is required. Intensity and uniformity of lighting illuminance, the requirements for lighting range are not high. At present, the illumination system of biological microscopes mainl...

Problems solved by technology

At the same time, traditional biological microscope illumination systems generally use halogen lamps or tungsten filament lamps as light sources, which can meet the requirements of illumination intensity, but have a short service life. Therefore, the advantages of high intensity and long service life of LEDs need to be replaced. Introduced into the design of the lighting system of the biological microscope to increase the service life of the lighting system
