  • 將兩個光電二極體訊號相減以進行差動偵測
  • 提高微弱或調變光學訊號的訊噪比（SNR）
  • 高共模雜訊抑制，提升量測靈敏度與準確度
  • 提供適用於 UV-VIS 與 NIR 光譜範圍的 Si 與 InGaAs 型號

平衡光接收器採用真差動偵測，將兩個匹配光電二極體的光電流相減，產生與兩個輸入之間光功率差成比例的單一電氣輸出。這可抑制雷射強度波動等共模雜訊，進而提升 SNR 與量測靈敏度。平衡光接收器採用低雜訊跨阻放大器設計，可確保精密光學量測的穩定一致效能。這些光接收器提供適用於 UV-VIS (320–1000 nm) 與 NIR (800–1700 nm) 光譜範圍的 Si 與 InGaAs 型號，非常適合相干光學偵測、干涉量測、光譜學及光學同調斷層掃描（OCT）。

注意：電源供應器另售。請參閱規格以了解更多詳細資訊。
