Latab Ring lights offer almost homogeneous illumination of objects at their working distance. Due to the almost parallel alignment of the emitted light to the camera, shadows are reduced to a minimum. By using an optional polarizer/analyzer, a significant improvement in contrast and a reduction of reflection are possible. Ring lights are available in a wide range of sizes from 44 mm to 348 mm. In addition to the standard colors (red and white), the lights are also available in blue, green, UV, and IR.
