What Types of Optical Filters Are Used in Nanotechnology?
Several types of optical filters are utilized in nanotechnology, including:
Dichroic filters: These filters reflect one range of wavelengths while transmitting another, often used in fluorescence microscopy. Bandpass filters: They allow only a specific range of wavelengths to pass through, useful in spectroscopy and imaging. Notch filters: These filters block a specific range of wavelengths and are used to eliminate unwanted laser lines in Raman spectroscopy.
