Whereas some optical assembly applications require optical clarity across a certain wavelength, others require an opaque coating. Optical grade epoxies, silicones and UV curable coatings provide the versatility to adhere well to a wide variety of substrates and the critical performance properties necessary. Learn more about optical transmission, refractive indices, temperature and humidity testing, and more, and the roles these measurements in choosing an effective and reliable optical polymer system.
