LIGHT BOX SCALE ANGULAR FOR RAYS

• PA2060-090

Light Box Kit part, white scale of angles for a full circle. 165x165mm square, designed to be used with lenses and prisms to measure angles of reflection and refraction and angles between rays. This device fits inside the kit housing and avoids the marking of rays on paper and then the measuring of the lines on the paper with a protractor. This is NOT normally part of the standard kit of Light Box parts.
