Bandpass filters allow light within a specific wavelength range to pass while blocking wavelengths outside that range. They are useful in spectral imaging and analytical chemistry
Shortpass Filters
These filters transmit wavelengths shorter than a specified cutoff and block longer wavelengths. They are often used for ultraviolet and blue light detection
Longpass Filters
In contrast to shortpass filters, longpass filters transmit wavelengths longer than a specified cutoff and block shorter wavelengths. They are used in fluorescence imaging and other applications needing isolation of longer wavelengths
Notch Filters
Notch filters block a narrow band of wavelengths while transmitting all other wavelengths, making them suitable for laser protection and Raman spectroscopy
Neutral Density Filters
These filters reduce the intensity of all wavelengths of light uniformly without altering the color balance. They are commonly used in photography to prevent overexposure in bright conditions
Dichroic Mirror
Dichroic filters use multiple thin film layers to reflect unwanted wavelengths and transmit desired wavelengths. They are highly efficient and used in applications requiring precise wavelength selection, such as fluorescence microscopy and laser system
