摘要： A spectroanalyzer accurately spectroanalyzes in spite of the deterioration of transmissibility of an optical fiber (5) by radiation, by using a light from a sample cell (1) as a measurement light which passes through the optical fiber (5). The spectroanalyzer comprises a white light source (15) for directing a monitoring light to a one end (5b) of the optical fiber (5), and a half-mirror (3) arranged in front of the other end (5a) of the optical fiber (5) for reflecting the monitoring light, which is modulated to permit the discrimination thereof from the measurement light. Accordingly, a degree of deterioration of the optical fiber (5) can be determined from the monitoring light, and the affect of the deterioration of the transmissibility can be corrected by dividing a measurement light power by a monitoring light power so that the accurate measurement of the sample cell 1 is attained in spite of the deterioration of the transmissibility of the optical fiber (5).

摘要： A method of producing an oxide glass thin film includes a process to obtain a transparent glass film, in which volatilization of additives in a porous film deposited is effectively suppressed and which can provide an oxide glass thin film having a desired arrangement of refractive index with a low optical loss. The method is for producing an oxide glass thin film, in which glass fine particles mainly containing SiO.sub.2 with additives are deposited on a substrate to form a porous thin film and then heated to form a transparent glass film. In the method, vapor of oxides of additive components is mixed in an atmosphere in which the porous thin film is heated to form the transparent glass film, whereby stopping the volatilization of the additives in the porous film deposited, preventing diffusion of the additives added to a core layer, and preventing the volatilization of glass transition temperature lowering components of additives (P.sub.2 O.sub.5, B.sub.2 O.sub.3, GeO.sub.2, etc.). By these, a desired arrangement of refractive index may be obtained, and an oxide glass thin film may be obtained while lowering the optical loss such as the optical scattering, which could be caused by bubbles in an unsintered portion.
