In this OPU, we use a triplet lens to collimate the laser beam. 在該系統(tǒng)中，我們采用三片式準直鏡來對光束進行準直。

Heteroaxial Double Half-cylindrical Lens Collimate Beam of Laser Diode[J]. 引用該論文 馬華

An incandescent bulb and fiber were used to collimate light into this speedometer indicator. 白熾燈泡和光纖利用使光平行打入到里程計指標。

Today's LEDs have reflector cups and focusing optics to focus and collimate their output. 今天的LED讓反射杯和焦點的光學來焦點和校準他們的輸出。

In order to design optical system to collimate laser beam, its far-field distribution should be acquired exactly. 為了合理地設計光學系統(tǒng)以整形激光二極管出射光束, 必須準確了解激光二極管的遠場分布,然而對于大功率激光二極管仍沒有形式簡單并且較好反映實際器件特性的光束模型。
