What is optical adhesives?<\/h1><\/h1><\/div>

This article mainly introduces the application of optical adhesive, and the optical factors and environmental factors to be considered in the application.<\/p>\n<\/div>

Application of Optical Adhesives<\/h3><\/h3><\/div>

Adhesives (bonds or cements) are used in optics for two main purposes:<\/p>\n

    \n
  1. To bond optical elements to their housing, and<\/li>\n
  2. To bond optical elements to each other, including lens to lens (for\u00a0doublets or triplets) and prism to prism (for beamsplitters).<\/li>\n<\/ol>\n

    When determining how to join the optical elements, the right consideration must be taken when drawing the element to be cemented and then choosing the right adhesive to achieve the best results.
    \nThese considerations are made by the optical designer while designing the optical elements to be bonded.
    \n(Bonding optical elements to their housing should be performed according to relevant written procedures that also include instructions for inspection and tests to verify the conformity of the bonding results to the written requirements. Those requirements are established by the designer and are not a part of this guide.)<\/p>\n

    UV-curing adhesives (Figures below) are one-component materials that\u00a0are cured upon exposure to UV light. These UV adhesives dominate the\u00a0market for bonding optical elements due to their ease of use and fast cure time. This chapter refers basically to UV materials. Most of the following descriptions apply to other optical adhesives (two component cements), as well.<\/p>\n
