A single-point fluorescence detector measures the total integrated signal independent of the spatial light distribution. The most important filter specifications to consider are the levels and ranges of the transmission and blocking regions. If only a single fluorophore is to be used, a long-wave-pass filter rather than a bandpass filter can be used to maximize signal. However, this usually increases noise (background signal) even more, so is not an optimal choice. Read more here.

Many of the most useful fluorescent probes have small separations between their peak excitation and emission wavelengths. These so-called small Stokes Shift probes have presented a historical challenge to optical filter manufacturers, because the critical edges of the passbands could not be placed too close together, at risk of overlap due to filter manufacturing variability.

Optical filters are critical for precision imaging, fluorescence applications, and laser-based systems, but small miscalculations can lead to signal loss, distortion, or suboptimal performance. Choosing and specifying the correct optical filters is crucial to success in these types of biological experiments. Here are examples of three common optical filter mistakes and how to avoid them.
