OPTICAL FILTER AND OPTICAL MEASURING EQUIPMENT EMPLOYING THE OPTICAL FILTER

摘要

Provided are an optical filter and an optical measurement device using the optical filter. The disclosed optical filter selectively transmits particular wavelength of light from incident light. The optical filter comprises at least one pixel. The pixel comprises: a first reflective plate which is configured to receive incident light, and has a plurality of first holes formed therein; and a second reflective plate which is configured to receive incident light transmitted through the first reflective plate, faces the first reflective plate with a predetermined gap therebetween, and has a plurality of second holes formed therein.
