The Isolight Puck light and color sensor is an ideal companion for image quality testing or camera calibration. No matter your scene size, the Puck lets you quickly set and verify your lighting including color, light level, and uniformity. The Puck is small enough to fit in small areas or be embedded in a scene. By arranging multiple Pucks into a group, you can measure lighting brightness and color uniformity across any size test chart.Add the Imatest Puck Plate to make checking uniformity fast and easy.
