1.投射比:镜头到画面距离除以画面宽度
Projection ratio: distance from lens to picture divided by picture width
2.9点亮度均匀度:9点平均亮度除以其中的最高亮度
9 brightness uniformity: 9 points average brightness divided by the highest brightness
3.与标镜9点均匀亮度光衰比例:镜头9点平均亮度除以标镜9点平均亮度
Light attenuation ratio of uniform brightness at 9 points of the standard mirror: average brightness at 9 points of the lens divided by average brightness at 9 points of the standard mirro
CAUTION(注意)
LE DU Lens Unit User’s Manual
(镜头部件 用户手册)
Do not give a shock or excessive load to the projector or the lens components as the projector and lens components contain precision parts.
(因为投影机和镜头部件包含精密零件,所以不要对投影机或镜头部件进行剧烈震动或超负载)
When shipping the projector with the lens,remove the lens before shipping the projector. The lens and the lens shift mechanism may encounter damage caused byimproper handling during transportation.
(运输带有镜头的投影机时,运输之前需移除镜头。搬运期间处理不当可能会损坏镜头和镜头位移机制。)
Before removing or installing the lens, be sure to turn off the projecttor, wait until the cooling fans stop, andunplug the power cord.
(移除或安装镜头之前,务必关闭投影机,等待直到冷却风扇停止运转,并拔出电源线。)
Do not touch the lens surface when removing or installing the lens.
(请不要在移除或安装镜头时触及镜头表面。)
Keep fingerpeints, dust or oil off the lens surface. Do not scratching.
(防止指纹、灰尘或油附着到镜头表面。请不要刮伤镜头表面)
Work on a level surface with a soft cloth under it toavoid scratching.
(请在水平面上作业,并在镜头底下铺一块软布以免刮伤。)
When using the lens unit, set the lens shift adjustment to the center of the screen.
(当使用镜头部件时,将镜头位移设定至屏幕中央。)
Adjustment to the lens shift adjustment to the position other than the above can cause the edges of the image to become dark or can cause some shadows.
(将镜头位移调节到上述位置以外的其它位置,可能会使影像边缘变得暗淡或者造成黑影。)
