InaerospacespacewhyWill use ultra narrow filters,What are the requirements for filters in the aerospace environment?

With the further development of human technology, after conquering mountains and oceans, humans have turned their attention to the distant sky and explored the unknown realm of space. Since exploring distant space, humans have continuously upgraded their tools, witnessing the rapid advancement of optical technology from the beginning telescopes to the present space telescopes.

Because when observing specific objects in space, we need to filter out a large amount of background radiation interference to improve the signal-to-noise ratio of the observed objects. Therefore, ultra narrow filters are an indispensable part of space remote sensing detection.

So we can see that for ultra narrow filters, there are relatively high requirements in terms of technical indicators, such as the coating process, coating materials, and coating technology. In order to meet the technical requirements of ultra narrow filters,Ruiyan Optics adopts hard coating technology and hires industry experts to jointly launch ultra narrow band filter products for space applications.

Ruiyan Optics can use narrowband filters and ultra narrowband filter products in space. Our company can provide spatial certification materials and radiation experimental environment certification materials (issued by a third party); Test reports before and after the irradiation total dose experiment, etc
