ASIS M1i - Infrared

All Sky Imaging System


The Solmirus All Sky Imaging System M1 (ASIS-M1i) is a dedicated purpose sky imaging and analysis instrument designed to operate autonomously or as a component in an instrument cluster. The ASIS is a ground based cloud detection and sky analysis system with applications ranging from astronomy, to solar forecasting, to a variety of meteorological applications.

In contrast to the ASIVA, the ASIS is designed for single purpose production applications in mind. The ASIS comes in two models the ASIS-M1i (Infrared) and the ASIS-M1v (Visible).
