New optical resins from Panacol for imprint and optical bonding applications will be on display at the SPIE Photonics West trade show in San Francisco. These new adhesives are typically used for light carpets in the automotive industry, for sensors in wearables or to generate structured light in projectors or time-of-flight sensor applications for automotive and consumer products.
Optical properties on polymer substrates
The new generation of materials has good adhesion to novel polymer substrates such as optical PET, PC or COP. They are suitable for glass wafers. After application and imprinting, these materials cure quickly under UV light and form a precise and durable structure. The optical properties are tailored to the requirements of the target substrate.
Producing microlenses
The Vitralit UC 1633 adhesive is characterized by further improved resistance to yellowing as well as increased optical transmission and dimensional stability. It can be easily removed from PDMS molds and is therefore suitable for the production of microlenses. For other optical applications and assembly, Panacol offers black UV-curable materials such as Vitralit BL UC 1103 for shading and masking properties.
