TESTING APPARATUS OF LASER USING CONER CUBE PRISM

摘要

The coner cube prism and the optical elements are provided in the vacuum chamber so that the wavelength of test laser and the interference colour between the test and standard lasers can be measured without any compensation. The chamber(CHA) comprises a vacuum pump(VC) for maintaining vacuum in the chamber, a window(3) for receiving standard laser(1) and test laser(2), the light devider(5) for reflecting and transmitting the laser at the right angle, detectors(4') for detecting the laser from a divider, coner cube prism(a)(a,) for total reflection to the total reflection mirrors(6)(6,)(14)(14,).
