The paper is devoted to application of circular laser writing system for manufacturing of diffractive elements on spherical surfaces. Laser writing can be made on photoresist film or directly on thin chromium film coated on convex or concave spherical surface.
This article presents the design concept of near-field scanning attachment for terahertz spectrometer frustrated total internal reflection.
The article presents the results of simulation software encoder for automatic focusing of laser radiation in a circle laser writing system and the results of its use for the manufacture of binary lenses on curved surfaces.
