How To Evaluate the Quality of Rear View and Side Mirror?
Interior and exterior rear view mirrors are key safety components of a vehicle. Automotive rear view and side mirrors (or wing mirrors) are part of a car overall safety system. They enable drivers to see beyond the driver’s direct sight, without rear view and side mirrors, reversing, parking and switching lanes are challenging.
The mirror is a major part of the side mirror assembly and is made from a polished flat glass with a thin reflective coating on one side. Reflectivity and reflected image quality are two qualities to look out for.
High reflectivity is desired and a spectrophotometer is used to measure the reflectivity – using the spectral reflectance data. For reflected image quality, a Distinct of Image (DOI) meter like Rhopoint IQ-S is used. DOI is a measure of how clearly a reflected image will appear in a reflective surface.
