High reflectivity ceramic substrate
We can provide high-reflectivity ceramic substrates made from alumina ceramics as the base material.
Ceramic substrate with high reflectivity characteristics We can provide high reflectivity ceramic substrates made from alumina ceramics as the base material. Since no special additives or coatings are used in the manufacturing process, there is no concern about contamination in subsequent processes. It is possible to accommodate mass production equivalent to existing products, as equipment for conventional alumina substrates can be shared. Additionally, because it is composed of existing raw material groups, it does not contain any substances regulated by environmental regulations.
basic information
Reflective properties of high reflectivity ceramics A reflectivity of 92% (@450nm) has been achieved with high reflectivity alumina ceramic substrates. [Comparison] Reflectivity of general-purpose alumina ceramic substrate (Our model number: KA6): 89% [Evaluation sample] Sample thickness t = 0.82 [Measurement method] "Relative diffuse reflection method" based on barium sulfate.
