  • 提供更高的分辨率與更小的光斑在NIR波段 (750-1100nm)
  • 單色光源的球面像差更小(不足2μm)
  • Broadband AR Coating has <1% Reflectivity Between 750–1550nm

我們的 TECHSPEC® 近紅外消色差透鏡專為在 750 至 1100nm 範圍內為多色光提供最小化光斑而設計。採用我們的近紅外雙膠合透鏡(而非針對可見光而設計的標準雙膠合透鏡)，可將 RMS 光斑直徑從 43μm 降低至 22.5μm (例如在使用多色光時即可實現)。這些雙膠合透鏡的典型應用包括：用於近紅外的 CCD 成像透鏡、近紅外雷射的聚焦與擴束，以及用於光纖及近紅外 LED 的聚焦/準直透鏡。
