Fluorescence observation device with multiple groups of light sources at different angles, base frame and fluorescence microscope

Abstract

The invention discloses a fluorescence observation device, a base frame and a fluorescence microscope. The fluorescence observation device comprises a cover body, a multi-angle light emitting unit and a control unit, wherein the cover body comprises a light transmittance and heat insulation layer and a heat dissipation layer; the multi-angle light emitting unit is provided with a plurality of narrow-light field excitation optical elements; the narrow-light-field exciting light elements can be arranged on the heat dissipation layer in a heat conduction way to dissipate heat; light beams emitted by the narrow-light-field exciting light elements pass through the light transmittance and heat insulation layer; the multiple narrow-light-field exciting light elements at different angles are controlled by a control unit, and an irradiation angle is selected; the fluorescence observation device can be combined with a base to form the base frame, and the narrow-light-field exciting light elements can be arranged on the base, so that the irradiation angle of exciting light is selected, and the environment needed by fluorescence observation and recording is constructed.

Description

【Technical field】 [0001] The invention relates to a fluorescence observation device, in particular to a fluorescence observation device applicable to a fluorescence micro-optic device, a base frame for the fluorescence micro-optic device and the device. 【Background technique】 [0002] In addition to being used in industrial inspection, counterfeit banknote identification, and criminal identification, fluorescence technology has been extended to the analysis and tracking of genetic engineering and gene transplantation experiments in biological research in recent years, which has gradually increased the importance of fluorescence image identification and analysis. [0003] The so-called fluorescence here is mainly to irradiate a high-frequency light on the object to be observed with fluorescence characteristics, such as the anti-counterfeiting thread of banknotes, or the location of suspected bloodstains at the crime scene, so as to excite a lower-frequency fluorescence.

Problems solved by technology

[0011] Although the above direction can make the illumination uniform and increase the convenience of observation, if the heat generated by the light source assembly does not have a good heat dissipation pipe, so that when the heat is left in the light-shielding chamber, the temperature may still rise, resulting in the final The experimental results are not good, and in order to obtain the best lighting angle, it is necessary to design an additional mechanical or electronic adjustment structure. It is difficult to reduce the development cost, and it is prone to damage after long-term use. Additional maintenance is required, so there is still room for improvement.
