Optical measurement probe, and optical measurement device provided with the same

摘要

There are provided an optical measurement probe capable of obtaining a more stable measurement result, and an optical measurement device provided with the same. An incidence surface of an optical window to be used in a high temperature environment is covered by a deposited film. The optical window is formed of sapphire, and the deposited film is formed from SiO2. Adhesion of dirt to the incidence surface, and an influence, on a measurement result, of the adhesion of dirt on the incidence surface can thereby be prevented, and a more stable measurement result can be obtained.

主权项

1. An optical measurement probe structured to guide light generated in a high temperature environment to an appliance, comprising:
an optical window for transmitting light incident on an incidence surface; and a light guide for guiding light which has passed through the optical window to the appliance, wherein the incident surface of the optical window is covered by a deposited protective film which is formed from a lipophobic material and which protects the window from greasy dirt.
