Once the new material formulation is completed, a photo-cure manufacturing process has to be developed, characterized, and validated. Process engineers usually work with the material scientists and/or chemists to develop and quantify such process. Historically, there has been a disconnect between the scientist and the process engineers. This has been mainly due to lack of understanding of light measurement techniques and equipments. For example, the scientist may use a broadband light source with optical filters to initiate the photo cure process during their research phase. They usually characterize the light source in terms of wavelength and intensity. Such characterization usually requires accurate understanding of the light source spectra, filter spectra, radiometer spectra, and the radiometer calibration method. While these are simple engineering measurements, the scientists are not usually trained and/or have the right equipment to perform these measurements. Therefore they may not characterize and communicate their process to the process engineers correctly. For example, researcher may use a general-purpose radiometer with broadband spectral response, which may be calibrated at wavelength whereas the photo initiator may be sensitive to wavelength . Therefore, the radiometric measurements are not true photo cure process parameters. This problem may even get more complicated as the process engineers may even use different radiometers with different spectral response and calibration to establish and validate the photo cure process.

Digital Light Lab has developed a family of light delivery systems based on its AccuCure technology. These systems provide an accurate, precise light generation, delivery, and measurement to the material under test. The process engineers can easily configure these systems to prototype, characterize, and validate their photo cure process.
