TECHNICAL DEPT. Lenses Test Report KNAC0424ASM - IESNA Type II / Type III * * * * Material = PMMA Clear, Non-yellowing, 10-year guarantee** Full angle at 50% from maximum: ~150x160 Full angle at 10% from maximum: ~160x110 The light spots here represented refer to tests carried out with LEDs with 3mm dome and 2mm2 LES, ~250lm@LED www.khatod.com technical@khatod.com Page 11 - May 2018 TECHNICAL DEPT. Lenses Test Report Materials Material PMMA 8N ** For further information please visit Evonik website Top -40...90C ** KNAC04xxxSM is made of the same material used to produce PLEXIGLAS(R) Solar which guarantees it will show no yellowing for 10 years. Yellowness Index (YI) according to the test standards for Arizona/Florida outdoor exposure testing: - YI 6 under hot/dry conditions - YI 8 under hot/wet conditions Notes: * * Intensity (I) and illuminance (E) data are normalized by 1000 lm The optical values shown are the result of optical simulations carried out with LIGHTOOLS, ASAP and ZEMAX software systems. The optical simulations are carried out on the basis of the typical values provided in the LED manufacturers' official datasheets. The photometric analysis has been carried out on physical samples. On request, by supplying your PCB, we can provide the measurement photometric file.
