What does DMC in UV mirror mean?

1。 DMC: Digital Multilayer Coating

Hoya/ Kengo likes some nice names:

The standard coating is that both sides of the lens are coated, with an average light transmittance of 94-95%.

Multi-layer coating (MC) means that there are three layers of coating on both sides of the lens, and the average light transmittance is 98-99%.

Super multilayer coating (SMC) is a kind of coating with five layers on both sides of the lens, and the film is transparent and easy to wipe, which is called 5+ 1 coating, with an average light transmittance of 99.7%.

Digital Multi-layer Coating (DMC) is a special coating with 65,438+0 layers on the back of SMC lens, which reaches the first 6 layers and the last 7 layers, specially for DSLR to absorb and reflect. Theoretically, DMC lens coating can reduce lens glare and ghost to a greater extent through digital optimization.
