What does a Cementer do?

Cements optical elements together to form units which have specific optical properties: Cleans elements, using solvent, tissue, brush, and compressed air device. Holds elements together to verify fit. Applies cement to element surfaces, using glass rod. Presses and rotates elements together to remove air pockets and distribute cement evenly over joined surfaces. Centers and clamps elements together. Places elements in curing oven for specified period.
