SP-超短焦T棱镜抗光幕 ｜ALR Fabric for UST Projector
点击查看视频 ›› 建议『超清模式』下观看效果更佳！
幕布特点
T棱镜抗光幕采用梯形物理结构纵向均布无数T棱镜双面物理结构，经科学严格计算和实验最终确认其角度，将自然光和超短焦投影机光线自动分离，利用精密的定向涂覆技术，将多层功能涂层均匀涂覆于反光面，仅在吸光面留下少许反光材料涂层（基本保持黑色状态），通过吸光面将约93%的环境光吸收，达到抗环境光功能。利用反射面的多层定向涂覆技术，提升投影画面对比度、色彩还原度、增益比、视场角达到最佳组合，将近85%投影机光线反射到人眼睛，使观看者在自然光下观看如同在昼夜环境下观看效果，即使明亮客厅使用，依然呈现4K超高清画面。
适用投影机：4K短焦、超短焦投影机（投射比 ＜0.4：1） 适用环境：明亮（500Lx）环境下 适用场所：客厅娱乐、家庭影院、教育教学等
Fabric Specs
T prism ultra-short-focus anti-light screen, using special trapezoidal optical physical structure, automatically separates the natural light and ultra-short-focus projector light, and absorbs ambient light on the light-absorbing surface by about 80% to achieve anti-ambient light function.Using the multi-layer directional coating technology of the reflective surface, the projection screen contrast, color reproduction, gain ratio, and angle of view are optimally combined, and nearly 85% of the projector's light is reflected to the human eye, so that the viewer can view it under natural light. Watching the effect in a day and night environment, even in bright living rooms, it still presents 4K Ultra HD.
