The ACR-120 provides the controlled diffuse illumination necessary for making ambient contrast ratio measurements of displays of all sizes, from cell phone displays to projection TVs. The ACR-120 consists of a 12-inch sampling sphere with an external fiber-coupled light source and a sphere monitor photo detector. The sampling sphere is designed to be placed in front of the display being tested, while the display is measured using a spot photometer though a view port on the sampling sphere.
- Supports diffuse reflectance and ambient contrast measurements per ICDM, VESA 308-1 and VESA 308-2
- Includes Built-in sphere monitor detector, fiber-coupled lamp and calibrated reflectance standard
