Infrared refractometer measurements of adhesives.
The real part of the refractive index of the optical cements, Eastman Kodak, HE-79; Lensbond, M-62; Epotek, 301 and 310; and Loctites, 307, IS-06, IS-04E, IS-12 (the latter three are Super Bonders), have been measured. The values are reported in most part over the 1-5-microm wavelength range. The samples were measured in a setting to which they are subjected in normal optical use. The technique used to obtain the values in this manner was an Abbé ir refractometer. The composite range in indices is from 1.46 to 1.54. The precision of the instrument and the accuracy of the data are discussed.
