Optically Clear Encapsulants

CAPLINQ OPTOLINQ™ OLS-Series are a family of optically clear (often called “water-white”) liquid encapsulants that are used to encapsulate optical or optoelectronic devices that require both a high level of light transmittance as well as a good level of mechanical protection. Products in this OLS-Series family can be epoxies, silicones or hybrid technologies. They are used extensively for the encapsulation of LED devices, but could be well suited for other applications that require a clear, optical grade encapsulation system.

Clear Liquid Encapsulants and Casting Materials for a range of applications

Used in a range of applications ranging from optoelectronics opt-couplers or LED devices or even used for casting components, CAPLINQ Optolinq series materials maintain water-white clarity even when exposed to higher temperatures or UV radiation.
