7.Bruker TruLive3D emission filters and fluorophores spectrum
This page will help you figure out which filter combination you need for most commonly used fluorophores on the Bruker TruLive3D.
The Bruker TruLive3D light sheet microscope has two imaging cameras with two motorized filter wheels and two sets of filters. It is designed to split different emission wavelengths between the two cameras for simultaneous imaging with two different emission channels.
The "Long Camera" will record the fluorescence emitting at the longest wavelength and the "Short Camera" will record the fluorescence emitting at the shortest wavelength.
When you set up your experiment you want to make sure that you select the best filter option for each camera so that the fluorescence from one fluorophore does not mix up with the other.
The Bruker TruLive3D has the following emission filters options:
Filter wheel Short Camera: BP418-462 LP498 BP497-554 BP580-627 BP610-651
Filter wheel Long Camera: LP498 BP497-554 BP580-627 BP610-651 BP655-704
To select the appropriate filters you need to know the emission peak wavelength of the fluorophores you are using.
