Standard for Lens Quality Measurements for Pattern Projecting Luminaires Intended for Entertainment Use
ANSI E1.35 - 2013 (R2018), Standard for Lens Quality Measurements for Pattern Projecting Luminaires Intended for Entertainment Use, describes a method for measuring stage and studio luminaire lens quality with particular emphasis on contrast and perceived image quality (sharpness). It also offers a way for presenting these results on a datasheet in a format that is readily understood by a typical end-user and that allows the end-user to directly compare lenses in a meaningful way.
