摘要：A method for forming an optical component includes (i) depositing opticallayers on a base, and (ii) controlling a thickness of a tuning layer by (a) depositing thetuning layer on the optical layers, (b) measuring a first optical characteristic, (c) measuringa second optical characteristic after continued deposition of the tuning layer, (d)

determining whether the second optical characteristic has decreased compared to thefirst optical characteristic, (e) when the second optical characteristic has not decreased,continuing deposition of the tuning layer and returning to steps (ii)(b)-(e), when thesecond optical characteristic has decreased, terminating the depositing and removing aportion of the tuning layer formed during a period of time defined from when anincrease/decrease of the second optical characteristic is stopped to when the secondoptical characteristic is changed to be decreased, and (f) adding a layer of a lowerrefractive index on the tuning layer.
