UltraFlat Dichroics for Distortion-Free Reflection
Dichroic beamsplitters (mirrors) are used as light guiding optics that reflect a specified range(s) of wavelengths and transmit a different specified range(s) of wavelengths at a specified AOI, typically 45 degrees. Most of Chroma’s catalog dichroics are intended for use at 45 degrees AOI. (For other uses, check with Chroma.)
Chroma manufactures UltraFlat dichroics for laser applications that demand superior levels of surface flatness, such as TIRF and other super-resolution techniques. Chroma offers UltraFlat dichroics either for use as individual parts or included in assembled filter sets.
However, the secret with flat dichroics is that they need to stay flat in your imaging system. Filter cubes that use clips, springs or screws to hold dichroics will torque them out of flatness. Chroma’s TIRF & Super-resolution filter cubes keep your dichroics just as flat in your microscope as they were when they were manufactured.
Dichroics are a necessary component of filter sets used in epifluorescence configurations. Most of Chroma’s dichroics, which are intended for more routine widefield fluorescence applications, neither have nor require high levels of surface flatness, but still deliver the other performance advantages of sputtered interference filter coatings.
