Is the telescope coated with FMC or SMC?

T* multilayer coating: The most famous is the T* multilayer coating technology in carl zeiss. T* lenses are generally plated with 6 layers, and 8 layers are also used when necessary. Later, it was known that the high imaging quality and warm color of Zeiss lens were due to the exclusive T* coating technology developed by Zeiss.

SMC coating: the reflectivity is extremely low, only 0.2%, and the light transmittance can reach 99.8%. SMC coating enables Pentax lens to get the image of Gao Fancha under any circumstances, and the color is gorgeous. Then in 1972, many photographers used Pentax Takumar lens with SMC coating technology, and achieved good results in many photography exhibitions. Since then, Pentax's SMC coating technology has become well known.

EBC coating: Fuji's unique coating technology, EBC coating has been praised for its good anti-glare ghost ability and bright colors.

Carl zeiss's T* coating technology, Fuji's EBC coating technology and Pentax's SMC coating technology mentioned above are recognized as the three major coating technologies in the world.

As for FMC broadband coating, at present, many telescopes in China are widely used, and I have found many articles but I have not figured out what it means.

To sum up: you need to buy a good telescope, not only by looking at the parameters in the publicity, but also by choosing a good brand.
