OPTICAL COATINGS
Optical coatings have a crucial role in the packaging of the optical components, optimizing the properties of the device at hand. Inkron develops and manufactures optically clear low and high refractive index (RI) coatings.
Low refractive index (RI), optically clear, gap filling coatings. RI range from 1.1 to 1.4.
High refractive index coatings. RI range from 1.55 to 1.9x.
OPTICAL COATINGS
APPLICATION
Product overview
The inherent properties of siloxane, Inkron’s main resin system are perfect for optics and optics-related applications and devices. The optical clarity of the resin systems combined with good durability and thermal stability makes siloxane the material of choice for a multitude of applications. Combined with Inkron’s capability to modify the polymers according to the application requirements this creates an excellent starting point for various optical designs. The final products are formulated in-house to meet the application-specific demands.

OPTICALLY CLEAR ADHESIVES
OPTICAL COATINGS
Inkron’s optical coatings are Nano Imprint Lithography processable and used for application in diffractive optics. Applications cover AR/MR waveguides, 3D sensors, other NIL-based applications as well as general optics applications.
NIL processable resins, RI range 1.55-1.9x
These high refractive index materials are complemented by low refractive index coatings. Typical applications are seen in antireflection coatings, cladding layers, gap filling.
Low RI gap filling coatings, RI range 1.1-1.4

APPLICATIONS
OPTICAL DIELECTRICS
The portfolio of optical dielectrics contains both inks and coating solutions. Screen printable solvent-free dielectrics guarantee pinhole-free insulation while maintaining transparency. The k-value of the basic systems is approximately 3, with the option to tune the formulation for higher and lower k-value products.

ADHESIVES
APPLICATIONS
Product overview
The materials for printed electronics applications form a complete package of conductors, dielectrics and adhesives. These products are fully compatible with each other. There are inks for both screen printing and inkjetting. The products include highly stretchable versions and optically clear inks with the possibility to tune the refractive index. The conductors and dielectrics are complemented by structural adhesives and underfills often needed in In-Mold-Electronics. Inkron controls the whole process starting from the synthesis of the polymers to the final formulation, and so can quickly modify material properties to satisfy customer specifications.
