Title: Amorphous carbon film
Inventor: INOUE TORU
IPC: G02B6/12
Filed: 2000-07-10
Abstract: PROBLEM TO BE SOLVED: To form an amorphous carbon film having parts different from each other in refractive index and used as a light path for IR without controlling voltage by using dielectrics different from each other in dielectric constant.
