Tech Tip 18 - Understanding Optical Properties
Index of Refraction & Spectral Transmission play a critical role in optoelectronic applications involving epoxies. Index of Refraction is the measurement of the speed of light within a certain substance. Most epoxies have a refractive index range from 1.50 to 1.57. In order to select the best optical grade adhesive, users need to specify the spectral transmission versus wavelength targets. As an example, it is common for a given epoxy to have a characteristic of being infrared transparent... (read more)

which is normal to the sample and then measuring the reflectance and interference from the same geometry. Depending upon the nature of the coating ultra-violet, visible or near infrared wavelength measurements may be necessary to obtain an optimum fitting of the measured curve relative to the theoretical reflectance curve. The theoretical curve is developed from a database of optical constants (n and k). The “n ” value is the refractive index and “k ” is the extinction... (read more)
