The refractive index:
This is one of the most common lens parameters, the refractive index, by definition, is the ability of a lens to bend light.
Under the same conditions, the higher the refractive index, the thinner the lens.
The common refractive index is 1.50 (1.49, 1.51), 1.56 (1.55), 1.61 (1.60, 1.59), 1.67 (1.66), 1.71, 1.74 (1.73). The refractive index of some materials in parentheses will be deviated from the standard refractive index value, which also belongs to the normal category.
All of these are the refractive index of resin lenses (no way, they are all resin lenses now), which gets thinner and thinner in the future, that is to say, 1.67 refractive index lens is thinner than 1.56, and 1.74 is the thinest..
