  • 最高的分辨能力及色散
  • 低溝槽密度適用於更高階
  • 溝槽間距容差 <0.05%
  • Custom Sizes Available

Richardson Gratings™ 階梯反射繞射光柵具備卓越的分辨能力及色散,超越其他反射繞射光柵。這類光 柵的特性包括粗略溝槽間距、相對較低的溝槽密度,以及高閃耀角度,適合用於近紫外線至紅外線波長 (~20μm)。Richardson Gratings™ 階梯反射繞射光柵適合各種應用,例如體積精巧的高分辨率光譜儀,具 備高角度色散及光通量。可依要求供應客製尺寸。

注意: 本系列光柵的表面非常敏感,操作時絕對不得碰 觸。如果需要清除粉塵粒子,建議以乾淨的壓縮空氣進行非接觸式清潔。
