Fluorescence filter is a key optical component used in life science instruments and biomedical applications. Its main function is to select and separate the excitation light and emission fluorescence characteristic spectral bands of substances in fluorescence inspection and analysis systems such as biology and medicine, and then observe them through a fluorescence microscope. Fluorescence filter generally consists of three combinations, namely excitation filter, dichroic mirror, and emission filter. Fluorescence excitation filter, also known as Excitation Filter in English
When the laser beam is perpendicular to the center of the mirror, the focusing quality is good. If the laser beam is tilted towards the mirror, the focusing quality will be greatly reduced, the focusing size will be significantly increased, and the optical power density will be greatly reduced, directly affecting the quality of power cutting. We carefully checked the optical path of the lens and determined the laser incidence positions at the four corners. Only by meeting the standards can we ensure the stability of the laser processing power density during the entire aperture operation. Secondly, use an optical path vertical calibrator, Zai
Fluorescent light sources are mainly used in fluorescence microscopes and are fundamental tools in cell biology. They consist of optical systems such as light sources, filters, lenses, etc. They use a certain wavelength of light to excite the specimen to emit fluorescence, and through the objective lens and eyepiece system, magnify and observe the fluorescence image of the specimen to achieve qualitative and quantitative research on the fluorescent sample. Excitation, filtering, imaging, quenching. The adjustment of fluorescence experiments essentially involves coordinating the above four factors to achieve the best results
The natural world is filled with electromagnetic waves, and the unit that distinguishes electromagnetic waves is wavelength. The wavelength range of visible light to the human eye is 380nm-780nm, with short wavelengths including ultraviolet, X-ray, and gamma rays, and long wavelengths including infrared, microwave, and radio waves. When electromagnetic waves are extracted at specific wavelengths, lasers are formed. The application of lasers in medical beauty mainly depends on their energy and penetration. Specific surface injuries can absorb lasers of specific wavelengths and destroy lesions through energy
New optical materials refer to optical materials with high technological content, high manufacturing difficulty, and excellent optical performance that have been developed in the past 10 years with the advancement of modern optics, optoelectronics, and information technology. Environmentally friendly series optical glass, low melting point, phosphate optical glass, etc. In the past decade, optoelectronic information technology has made tremendous achievements. In order to meet this rapidly developing requirement, it is necessary to seek new breakthroughs in broader cutting-edge fields such as transmission, exchange, data storage, and display
Deep ultraviolet filters are required in many situations. Narrow band filters at 220nm and 275nm are used in total nitrogen detection instruments that measure the total nitrogen content in water using photometry. For example, narrow band filters at 254nm, 265nm, 280nm, and other day blind levels are used in forensic testing. Due to the scarcity of materials that can transmit deep ultraviolet wavelengths below 300nm in nature, metal induced coating technology is generally used to produce deep ultraviolet filters
After a long period of continuous laser irradiation, optical transmission type components will undergo thermal deformation due to the increase in temperature, causing changes in the refractive index of transmission optical components and the reflection direction of reflection optical components. The thermal lens effect will change the position of laser focusing, thereby affecting the application effect. For pulse fiber optic equipment, after the laser is output from the isolator of the laser, it mainly passes through optical elements such as red light combining lens, galvanometer, and f - θ field lens. Due to the heat generated by the transmissive optical elements
We all know that optical quartz glass is a very good optical substrate material compared to ordinary optical glass, and its performance in all aspects is much better than other optical glasses. This also leads to the high price of optical filters produced using optical quartz glass. However, quartz glass also has its own advantages and disadvantages, and the production method affects the characteristics of quartz glass. The characteristics of quartz glass are ultimately formed in its structure, and are more or less affected by the raw materials, production methods, and processes used
Neutral density attenuation sheets are like sunglasses, protecting the eyes from strong light stimulation by absorbing excess light energy. Fiber optic attenuation sheets can work in a specific wavelength range like sunglasses to protect optical fibers. The standard for a good fiber optic attenuation sheet is to absorb additional optical fibers instead of reflective fibers, because in fiber optic communication, it is necessary to use lower optical power without damaging the fiber optic attenuation sheet. A neutral density attenuator based on the absorption of light by metal ions has been developed
