Title: Method for measuring coefficient of absorption of infrared optical crystal
Inventor: SUGIURA HISANORI
IPC: G01N25/18
Filed: 1989-04-14
Abstract: PURPOSE:To accurately measure the coefft. of absorption by specifying the surface roughness of the end face of the IR optical crystal to <=Hmax=1.5mum. CONSTITUTION:The absorption at the end face of the IR optical crystal 1 is largely affected by the polishing state of the end face, i.e. surface roughness when the above-mentioned crystal is irradiated with laser beam 2. The surface roughness of the end face of the IR optical crystal 1 is, thereupon, confined to <=Hmax=1.5mum to decrease the absorption at the end face at the time of measuring the coefft. of absorption of the crystal 1 by a calorimetric method using a laser type contactless outside diameter measuring instrument 3. The sepn. of the absorption at the end face and the internal absorption is accurately executed in this way and the accurate measurement of the coefft. of absorption is possible.
