A method for improving dispensing efficiency by penetrating a specific wavelength light source through a lens equipped with a filter

Abstract

The application discloses a method for improving dispensing efficiency by making specific wavelength light source penetrate the lens equipped with filter, including filter material selection, setting filter waveband range, calculating filter UV waveband minimum transmittance, equipping filter and testing, adjusting and optimizing, the application adopts the designed double waveband filter, aiming at the common hot glue way of the previous NIR lens, the gas generated during the lens baking causes the filter to float and generate gap, so that the lens quality is affected, by selecting the filter material with appropriate UV waveband transmittance and NIR waveband transmittance, only the required wavelength of light is reserved after the specific wavelength light source passes through the filter, and on this basis, the filter penetrable filter waveband and the required UV light source waveband of the glue curing are set, the filter UV waveband minimum transmittance is calculated to realize the best dispensing effect, the specific wavelength light source can penetrate the filter to make the glue curing, so as to improve the dispensing efficiency and quality of the lens equipped with filter.
