Draper Launches Ambient Light Rejecting Surface for Ultra-Short Throw TecVision XH800X UST ALR will Debut at InfoComm 2018RS Staff ⋅ Apr 30, 2018 Draper has added the TecVision XH800X UST ALR and CS1000X ALR, the latest additions to the company’s line of ISF-certified, 8K-ready viewing surfaces. After unveiling a massive rebrand at InfoComm 2017, Draper is celebrating a strong year with new solutions and innovations, with the TecVision XH800X UST ALR debuting at InfoComm 2018. TecVision XH800X UST ALR is a premium ambient light rejecting surface formulated for use with Ultra-Short Throw (UST) and short throw projectors in moderate to high ambient light applications for improved contrast and color saturation. This surface can reject 57 percent of off-axis ambient light while still being able to support extremely wide viewing angles, according to the company. [Draper Launches Ambient Light Rejecting Surface for Ultra-Short Throw] Available in NanoPerf up to 102-inch image height, the TecVision XH800X UST ALR works with lens throw distance ratio of 0.25:1 or longer for best brightness uniformity. “Most ALR screen surfaces are manufactured to reflect off-axis ambient light away from the viewer,” said Steve Cook, consultant relations manager for Draper Inc. “With TecVision XH800X UST ALR, Draper was able to pull off a formulation that rejects up to 57 percent of off-axis ambient light and has a reasonable gain of 0.8 without sacrificing much projection light or causing hot spotting issues. Short throw projection is an important tool in classrooms, where the lights need to be kept on for students and instructors to work together. TecVision XH800X UST ALR will dramatically increase the effectiveness of these classrooms.” In addition, the TecVision CS1000X ALR boasts Draper’s TecVision innovation with 82 percent ambient light rejection, making it ideal for spaces where there’s high ambient light with no way to control it. The TecVision CS1000X ALR’s half gain angle is 20 degrees and should be viewed within 30 to 35 degrees off-axis. A lens/throw distance ratio of 1.6:1 or longer is recommended. TecVision is available in sizes as large at 23 feet by 67 feet wide.
