Liquid-filled adjustable optical wedge applied for deflection of the laser beam

Olga Iwasińska-Kowalska

Abstract

Studies on the application of a liquid-filled variable angle prism as precise beam deflector are presented. The system operates on the basis of a liquid-filled variable angle prism. The basic idea is to use two flat optical plates separated by optical fluid. To avoid distortion of wavefront the liquid layer is very thin. The optical fluid has a refractive index matching the refractive index of plates. Plates are adjusted at an angle in order to obtain the optical fluid wedge between them. Theoretical basis, experimental set up and experimental results are presented. As a result a range of deflection 5·10−6 radians were obtained.
