The MAVO-SPOT 2 USB is a precision luminance measuring instrument with a measuring angle of 1°. This meter provides luminance measurements from a distance from 1 m to infinity, while taking into consideration the ambient light. The MAVO-SPOT 2 USB is equipped with a high quality SLR optical system. It has a viewing field of 15° and clearly marked measuring angle of 1° in the center, as well as an external focusing ring. Two optional close-up lenses allow the measuring distance down to 34 cm.
