Performance factors, selection and metrology of adhesives for optical applications

摘要

Several performance factors such as spectral properties, hardness, thermal stability, glass transition temperature, and outgassing need to be taken into consideration when selecting an appropriate adhesive. Optical applications require that the selected adhesive not only assure mechanical integrity of the assembled element but also support its optical performance. This paper discusses how to select an adhesive for some common optical applications and also demonstrates the use of analytical methods in the metrology of optical adhesives.
