Notch filters & band reflecting filters
What are you looking for in Stock?
Notch and band reflecting filters provide up to OD6 blocking for a selected wavelength or bandwidth. These filters are typically used for laser-based spectroscopy, raman and fluorescence measurements and other biomedical systems of the life sciences where the emission spectrum needs isolating.
In fluorescence detection it is necessary to block the excitation wavelength but allow the transmission of the fluorescence signal. This signal can be many orders of magnitude dimmer than the excitation wavelength itself, but very close to the emission wavelength. It is usual to have a set of transmittance, dichroic reflecting / transmitting, emission filters for a particular task, such as DAPI and Texas Red filter kits.
