Paper Abstract

There are still types of lenses that should to be glued on holder for polishing in the latter-day optical production. A negative effect during this process is a deformation of the optical surface caused by a different thermal expansion of the holder, glass and blocking pitch. This paper presents a numerical simulation of deformation of hemispheric lens which was verified by a series of experiments. A new segmented lens holder, which significantly suppresses mutual tension and therefore an amplitude of a surface deformation was designed based on the results. The lens holder reduces the surface deformation by approximately 30 times compared to standard holders. The most beneficial part of this work is a development of the precise simulation method that allows designing and optimizing the lens holder for an application before its realization.
