投影镜
(3)投影镜(projector lens):投影镜的功能是把中间镜形成的二次像及衍射 谱放大到荧光屏上,成为试样最终放大图像及衍射谱。
主要应用于光洁度要求高及超软材质的光学玻璃如:LCD液晶显示,ITO导电玻璃,数码相机镜头、投影机镜头。
If you are on the road and trying to get your projector set up in a hurry, this removes any doubt about the current position of the zoom lens, which can save you a few seconds.如果你是出差使用并且想很快就把投影机架起来演示的话,关闭此功能可以无视镜头的变焦位置,从而可以节省一点时间。
