The Upgrade to NextScan Lumintec

We upgraded to NextScan’s Lumintec lighting system yesterday. It uses LEDs (or more precisely, an array of strobed red LEDs) to illuminate the microfilm while it’s passing through the scanner rather than traditional halogen “hot lights.” Apparently, the CCD camera is more sensitive to the red wavelengths, and there are no IR emissions like you get from plain old “bulbs.”

Essentially, this was a quality-driven decision for us. The halogen bulbs tend to cause hotspotting in the middle of the image, an effect which is particularly noticeable on larger positive frames (such as the ubiquitous 35mm newspaper diazo readers found in nearly every public library nationwide, which represent a lot of the film that we process). Well . . . that issue is gone thanks to the Lumintec lighting.

It’s a night-and-day upgrade — lots more light (critical at higher reduction ratios, where the camera is physically more distant from the film) which lets us run stopped-down when appropriate, more even illumination, no heat, 1/10th the power consumption of hot lights (yes . . . we’re green!), sharper images and less blurring due to the strobing, no chance of lamp failure (changing the bulb was previously a rather labor-intensive operation and represented real down-time) , and, well, it just looks cool when it’s on. :-) Our microfilm customers will see an immediate improvement to the quality of their images.

Excellent example of a #FADGI compliant, high volume mass #digitization project yielding images that are measurably sharper, evenly illuminated, and with accurate colors and free from color casts, noise, and other unwanted artifacts. Actually shooting targets AND routinely *verifying* them with software ensures that your imaging system is performing correctly over the course of a long-running project and is a big part "doing it right" as defined by our nation's leading cultural institutions.Tis the season for mass digitization! We’ve digitized over 2,000 posters in our first few weeks of production with National Museum of American History Archives Center and we’re excited to finish the collection in the new year! If you’re home for the holidays, help us transcribe the catalog sheets for the posters: transcription.si.edu/node/40 over at Smithsonian Transcription Center ... See MoreSee Less
