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

Abstract

A fluorescence observation device, a base frame and a fluorescence microscope, wherein the fluorescence observation device includes a cover body, a multi-angle light emitting unit and a control unit, and the cover body includes a light-transmitting heat insulating layer and a heat dissipation layer, and the multi-angle light emitting unit has a plurality of narrow light beams Field-excited light-emitting element, the heat-conducting narrow-field-excited-light element can be arranged on the heat dissipation layer for heat dissipation, and the light beam emitted by the narrow-field-excited light-emitting element with directivity passes through the light-transmitting heat-insulating layer, and multiple groups are controlled by the control unit Narrow light field excitation light elements with different light emitting angles to select the irradiation angle. The fluorescence observation device can be combined with a base to form a pedestal. The narrow light field excitation light elements can also be placed on the base to select the excitation light irradiation angle. , to construct the environment required for fluorescence observation and recording.

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.
