2020年5月27日 · 在荧光显微镜观察和成像中，通过荧光光立方提供特定波长的激发光和对应的长波长发射光，从而通过肉眼、显示屏或相机采集荧光信号，因此，荧光光立方是决定可以检测到何种荧光信号的关键器件，其特性包含EX：激发波长滤光片参数，EM：发射波长滤光片参数和DM：二分镜参数。 什么是荧光? 荧光即为物质中的电子吸收光的能量由低能状态转变为高能状态，再回到低能状态时释放出的光，是非温度辐射光——冷光。即：物质吸收短波光，进入激发 …
Overview of Filters and Light Sources - Thermo Fisher Scientific
Understand your choices for light sources and filters. Learn how excitation and emission filters work and what types of light sources are available for fluorescence experiments.
Filters for Fluorescence Microscopy Tutorial - Thorlabs
An emission filter serves the purpose of allowing the desirable fluorescence from the sample to reach the detector while blocking unwanted traces of excitation light. Like the excitation filter, this filter only allows a narrow band of wavelengths to pass through it, around the peak fluorophore emission wavelength.
Fluorescence Filter Types - Chroma Technology Corp
The primary filtering element in an epifluorescence microscope is the set of three filters housed in a fluorescence filter cube (or filter block): the excitation filter, the emission filter, and the dichroic beamsplitter.
Excitation Filter in Fluorescence Microscopy
2024年9月24日 · Excitation filters are a fundamental component of fluorescence microscopy, ensuring that the correct wavelength of light reaches the fluorophore and produces effective fluorescence emission. By choosing the right excitation filter, researchers can obtain high-quality, high-contrast images while minimizing background noise.
