Introduction to Fluorescence Filters

Fluorescence occurs when a molecule absorbs light at wavelengths within its absorption band, and then emits light at longer wavelengths within its emission band. For example, brightly fluorescent molecules (called fluorophores) can be attached to biologically significant molecules in e.g. cell membranes, in the brain, or even on subunits of DNA, whose structures become visible in a fluorescence microscope that allows us to track the way cells function in health and disease. Fluorescence is widely used in biology, biotechnology, and medicine, due to its extraordinary sensitivity, high specificity, and simplicity of usage. Learn more about what optical filters are included in a fluorescence instrument and how Semrock optical filters can optimize your application. Learn More

Laser Damage Threshold

Laser damage to optical filters is strongly dependent on many factors, and thus it is difficult to guarantee the performance of a filter in all possible circumstances. Nevertheless, it is useful to identify a Laser Damage Threshold (LDT) of pulse fluence or intensity below which no damage is likely to occur. Laser damage may be broadly classified into two types: absorption-driven and dielectric-breakdown damage. Which type dominates depends on the material properties (absorption coefficient, specific heat, melting temperature, as well as defects that cause scattering and concentrated electric field effects), geometric properties of the sample (thickness, homogeneity, surface morphology, etc.), and of course the properties of the laser beam itself.
