[Aluminum Surface Treatment Problem Solving Case] Improving Heat Resistance of Optical Components to Prevent Stray Light

Maintains low reflection with excellent dimensional accuracy! Introduction of a case that does not discolor even after 140°C for 2000 hours.

Optical components for product inspection use a matte black anodized treatment to prevent unintended light reflections. However, conventional black anodizing uses organic dyes for coloring, which can decompose and fade at temperatures above 100°C. Therefore, we apply a heat-resistant matte black anodized treatment called "TAF TR SBK" to the surface of the components, which maintains its color even when heated to 350°C. Since it does not fade at high temperatures, it is possible to increase the operating temperature range of precision optical components. [Challenges and Background] - Recently, performance standards have become stricter, increasing the need to test product operation at high temperatures. - Conventional black anodizing uses organic dyes for coloring, which decompose and fade at temperatures above 100°C. - Fading of components reduces anti-reflection performance and compromises the accuracy of inspection devices. *For more details, please refer to the PDF document or feel free to contact us.*
