Ghost & Flare analyze

Software theory analysis

Use ASAP and Lighttools theory to analyze Ghost & Flare generation path

Theoretical analysis of Ghost&Flare generation path, and based on the energy intensity, adjust the reflectivity of the lens coating to reduce the poor imaging effect

Routing

Ion sputtering or planetary coating

Advantages: Solve the problem of high reflectivity at the edge of large curvature lens (uneven film); good adhesion of the coating, and the film is not easy to fall off; compounds/alloys/non-metals can be filmed

Absorptive IR

General reflective IR is easy to reflect the IR light and cause the reflection between the lenses or the sensor to cause ghosting or flare.
