[Optical properties of alpha-cyanoacrylate adhesives].

The growing increase in the production of medical endoscopes and their complicated design demand the use of materials and processes offering the whole complex of advantages. Assembly of rigid endoscopic systems presents great difficulties during cementing operations, especially when several adhesive joints should be obtained in a single optical element. Transparent, quick-setting alpha-cyanacrylate adhesives are of particular interest in view of their usage for cementing optical elements.
