For more realistic and larger-scale visual productions, further enhancement of the projector's capabilities is needed!
The "dichroic filter" has the ability to separate colors of light and is used for purposes such as expressing specific colors or cutting ultraviolet and infrared light. However, increasing the light intensity can cause the coating to absorb heat, which not only prevents it from demonstrating its film-forming performance but also poses a risk of damaging or degrading the substrate. Our company has a proven track record of combining various coating technologies to create coatings with complex performance characteristics. In this case, we provided a coating that maintains the required performance, such as UV cutting, while suppressing heat absorption and excelling in "heat resistance" and "laser resistance." [Case Overview] ■ Challenge: To enhance the durability of high-brightness projectors and achieve clarity in images. ■ Solution: Imparting "durability" and "laser resistance" through complex thin-film design and processing technology. ■ Featured Product: Dichroic Filter *For more details, please refer to the PDF document or feel free to contact us.
