Standard for Gobo Projection in Public Review

ANSI E1.35 - 2007, Standard for Lens Quality Measurements for Pattern Projecting Luminaires Intended for Entertainment Use, is being revised to increase the accuracy of the measurement procedure, while keeping it simple. The draft of the revised standard is available for free download and comment through 21 January 2013 at http://tsp.plasa.org/tsp/documents/public_review_docs.php.

E1.35 describes a method for measuring and stating the sharpness of the image projected by a stage and studio luminaire. It's meant to be a simple way to distinguish quantitatively between luminaires as to the crispness of their projected images.
