Model 116 & 124 Luminance Probes

For luminance measurements in difficult-to-reach places, such as in photocopiers or photolithography systems, UDT Instruments offers two luminance probes. Both are fiberoptic bundles, two feet long, which affix to the Model 211 sensor head. They may be calibrated in footlamberts or cd/m2. The Model 116 provides a 6.35 mm entrance aperture, while the Model 124's is 1.50 mm.
