About: Pellicle mirror

An Entity of Type: Whole100003553, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

A pellicle mirror is an ultra-thin, ultra-lightweight semi-transparent mirror employed in the light path of an optical instrument, splitting the light beam into two separate beams, both of reduced light intensity. Splitting the beam allows its use for multiple purposes simultaneously. The thinness of the mirror practically eliminates beam or image doubling due to a non-coincident weak second reflection from the nominally non-reflecting surface, a problem with mirror-type beam splitters. The name pellicle is a diminutive of pellis, a skin or film.

  • 半透明反光镜（Pellicle Mirror，或简称半透镜）是一种轻薄半透的光学材料，用于将一束光线分为两道独立的光束，属于分光镜的一种特例。其可以安装在单反相机中，取代原本的反光镜且不进行动作而获得额外的拍摄优势。 因为这类材料十分轻薄，也被称作半透膜。 (zh)
