Optical Filters

Only filters with high transmission characteristics ensure best sensitivity.

BRET and other colour luminescence applications are only possible with an extremely efficient optical system together with appropriate filters as used in the Mithras or TriStar readers. Especially when little emission light is present as in fluorescence polarization and time-resolved fluorescence measurements the readings can be performed with higher sensitivity and better reproducibility using appropriate filters.



The filters offered by Berthold Technologies are high quality filters with selected transmission and bandwidth specifications for the respective applications.
Customized filters or filter sets are available on request.

The best combination of excitation and emission filters can be given by our product specialists or sales representatives.
