Description

Filters are materials that have wavelength-dependent transmission characteristics. They are can be used to select the wavelength range of the light emerging from a light source, or the range entering the detector, having passed through the sample. In particular they are used in fluorometry to exclude wavelengths greater than the excitation wavelength from reaching the sample, preventing absorption interfering with the emitted fluorescence. Standard filters can also be used for calibrating purposes.
