ワーメータにおいて、受光面の面感度分布の一様
化、受光面の保護、耐パワー性の向上を求める手
段として、上記受光面の前に配置され、照射した
レーザ光を分散させて受光面全体に受光させる拡
散板を具備したことを特徴とするパワーメータ。 In a power meter that receives laser light and measures laser power, it is placed in front of the light receiving surface as a means for uniformizing the surface sensitivity distribution of the light receiving surface, protecting the light receiving surface, and improving power resistance. A power meter characterized by comprising a diffuser plate that disperses irradiated laser light and causes the light to be received over the entire light receiving surface.
