產品系列說明

全像擴散片可用於控制照明擴散區域,以及將燈絲、發光二極體(LED)、弧形燈及其他光源的穿透效率增至超90%。這些熔融石英全像擴散片採用熔融石英基材,使其工作溫度相比聚碳酸酯全像擴散片的工作溫度更高,並可提供可控均勻的光線分布。需要注意的是,擴散角度是按準直光入射下規範的,會隨入射角的不同而發散角度會有變化。

有別於其他的全像元件,這些聚碳酸酯元件可用在整個可見光及近紅外光範圍內。可見光波長下穿透光的零階或鏡面反射率小於1%,但若這些擴散片用在波長 400-700nm 的情況下,反射率可能會更高。

請注意: 磨砂表面應面向光源。 清潔全像擴散片時,可以用一塊不織布沾上甲醇,以輕柔的打圈方式輕輕地擦拭整個擴散片表面。之後需立即用乾燥的壓縮空氣小心地吹乾清潔過的擴散片區域。注意:清潔可能導致擴散片的光學性能發生變化。
