Microscopy Filters are used in a variety of microscopy applications for increasing contrast, blocking ambient light, removing harmful ultraviolet or infrared light, or for selectively transmitting only wanted wavelengths. Microscopy Filters are optical filters that are well-suited for use in microscopy. Microscopy Filters are commonly used in applications such as fluorescence, brightfield, or darkfield microscopy.
