GC-Black
Advanced Ultra-Low Reflection Film: GC-Black
GC-Black is an exceptional solution with a wide range of applications. It is designed explicitly for ultra-thin (≧0.21mm) and large-sized wafers or glass substrates (≦12"), offering unparalleled ultra-low reflection capabilities. This color-tunable black film exhibits an incredibly low reflection, ranging from 1% to 0.05%, covering wavelengths from ultraviolet to visible and infrared light.
Its remarkable characteristics set GC-Black apart from conventional organic absorbed black inks or coatings. GC-Black only has just a few hundred nanometers or less, it can obtain a minimal optical surface reflection performance. Additionally, it boasts outstanding features such as high hardness (≧9H), exceptional adhesion (≧5B), impressive heat resistance (≧400 Celsius degrees), and remarkable resistance to environmental testing.
GC-Black is a highly anticipated technology in black film for integrating with optical lens assemblies and semiconductor packaging production lines, including WLP (Wafer Level Package). Incorporating this black film into optical components effectively mitigates noise caused by stray light and crosstalk. This leads to substantial improvements in component performance, enhanced imaging quality, and extended detection distance, thereby elevating overall appearance and quality.
Furthermore, GC-Black offers a unique advantage with its simultaneous patterning and integration capability with other functional films like GC-BBAR and Filters, leading to even further enhancements in component performance. Embrace the possibilities with GC-Black, the advanced ultra-low reflection film that revolutionizes optical solutions for various industries.
