Multiband Optical Filters Find Applications Outside Fluorescence
Whether used for imaging cells or astronomical bodies, multiband filters can improve signal-to-noise ratio while reducing cost, size, and setup and data-acquisition times in optical systems and instruments.
In the past, most optical filters had a single transmission or blocking band at a particular wavelength. But today, the demand for multiband filters is surging in many areas of application. The benefits of multiband dielectric filters go beyond well-known fluorescence applications to...
