A 535nm bandpass optical filters with a full width at half maximum (FWHM) of 10nm is a type of optical filter that allows only light in a specific range of wavelengths centered at 535nm to pass through while blocking other wavelengths of light.
This type of filter is commonly used in applications such as fluorescence microscopy, flow cytometry, and spectrophotometry, where it is important to selectively isolate light emissions from specific fluorophores or chromophores. The 535nm wavelength range is often used to detect green fluorescence from dyes such as Alexa Fluor 488, FITC, or GFP.
By using a bandpass filter with a specific FWHM, it is possible to enhance the signal-to-noise ratio of the desired fluorescence signal and to reduce background noise from other sources of light. The FWHM of 10nm indicates that the filter will pass wavelengths ranging from approximately 530nm to 540nm, with the peak transmission at 535nm. This filter can be combined with other filters in a filter cube for multi-color fluorescence imaging and analysis.
