Astronomik MC Clear Glass Filter - 1.25"


Use the Astronomik multi-coated (MC) Glass Filter if your imager's focal plane needs to remain parfocal with other Astronomik filters. Multi-coating prohibits undesirable reflections. The MC Glass Filter substitutes for a UV-IR blocker provided your system doesn't have refracting elements.

This filter also protects your imaging system from dust. Since the filter doesn't alter the spectral transmittance of your system, it won't modify the colors. It provides an excellent method for keeping dust off your optics or sensor.

The Astronomik MC Clear Filter is made in Germany and is constructed via a sophisticated process identical to that used to make all other Astronomik filters. The coating features the same scratch resistance, while the substrate boasts the same high level of quality. Therefore, the MC Clear Filter is parfocal with all Astronomik filter designs and serves as a suitable dust protector for the front of DSLR cameras or for Schmidt-Cassegrain, Schmidt-Newtonian and Maksutov systems without adjusting spectral characteristics, and with no decrease in optical performance.
