How does a fluorescent filter work?
Fluorescence filters are key components in microscopy, used to selectively transmit light for exciting and detecting fluorescence. They include excitation, emission, and barrier filters. Excitation filters stimulate fluorescence, emission filters capture it, and barrier filters block excitation light. Specific filters, like DAPI, FITC, GFP, Cy5, Texas Red, Cy3, mCherry, and Rhodamine, are tailored for different fluorophores, aiding precise biological imaging.
What are Scintillation Materials？
Scintillation materials are substances capable of converting high-energy radiation like X-rays or gamma rays into visible or near-visible light. Widely employed in medical diagnostics, high-energy physics, and geophysical exploration, scintillators come in various forms including gaseous, liquid, or solid compositions, and can be organic or inorganic such as glass, single crystals, or ceramics.
