產品系列說明

精密的N-BK7基材
已針對用於具有小視場的平行光執行最佳化
穿透波前精度可達λ/16

許多光學系統都會出現某種程度的球面像差，球面像差會導致影像品質與整體系統效能受損。而TECHSPEC®球差校正板可在設計波長下補償校正球差。應將這些球面像差補償平板垂直放置，並放置在瞳孔附近。在具有小視場的系統中，這些平板具有出色的球面像差校正能力。

可以合併使用多個球面像差補償平板，以產生所需程度的補償性球面像差。負號平板可產生校正過度的球面像差。正號平板可產生校正不足的球面像差。

Note: The arrow on the spherical aberration compensation plates points in the direction of light travel.
