The application of vacuum technology in the production of fluorescent filters, the core components of PCR nucleic acid detection equipment
Fluorescence filters belong to the application of filters in the medical field. The fluorescence filter manufacturing technology is a complex engineering technology, involving many professional technical fields, including vacuum acquisition technology, vacuum measurement technology, computer-aided design technology, optical property testing technology, electronic circuit technology, material property testing, preparation technology, etc.
The high-quality fluorescent filter uses a single piece of colorless and transparent glass as the substrate and coats the two surfaces of the glass. In the vacuum chamber of the vacuum coater, the dielectric material is evaporated by heating or bombardment by an electron beam, and the vapor is deposited on the optical surface. Controlling heating, vacuum, substrate positioning, and rotation during evaporation can produce uniform optical coatings of specific thicknesses.
