SolEpoxy is excited to announce the commercial launch of OP50-2, a next-generation optical encapsulant engineered to meet the demanding performance requirements of modern sensor and device technologies. With exceptional clarity, thermal stability, a low coefficient of thermal expansion (CTE), and biocompatibility, OP50-2 represents a major step forward in material innovation for optical and infrared device design.

Engineered specifically to encapsulate sensors, transmitters, and receivers, OP50-2 offers excellent light transmission across a wavelength range of 400 nm to 1600 nm, making it ideal for infrared devices and selective sensors used in automotive, medical, and industrial applications. Its low CTE ensures dimensional stability even in extreme temperature conditions, while moisture absorption is reduced by 50% compared to industry standards. This enhancement significantly improves long-term reliability in challenging environments.

Recent tests have confirmed that OP50-2 is biocompatible and suitable for skin contact. This opens up new opportunities for wearable, medical, and human-contact devices, providing the clarity, durability, and safety needed for next-generation optical applications. Additionally, OP50-2 exhibits outstanding adhesion to materials such as silver, ceramic, PCB, and Nickel-Palladium-Gold (NiPdAu) substrates, supporting robust package integrity across various device configurations.

Furthermore, OP50-2 is MSL-1 capable, resists yellowing from UV exposure and heat aging, and maintains high optical transparency over time, ensuring consistent performance throughout manufacturing, assembly, and field use.

With its combination of optical precision, environmental durability, and proven biocompatibility, OP50-2 sets a new standard for encapsulants in advanced sensor technologies. Whether used in medical instrumentation, automotive safety systems, or industrial automation, this material is designed to perform where clarity, reliability, and long-term stability are paramount.
