ARコーティングが有効なケース
AR coating helps when reflection loss or ghost images affect performance. Single-side and double-side coating serve different mechanical and optical needs.
機械的適合性の重要性
Diameter, thickness, flatness, surface quality, and mounting stress can affect system performance even when transmission looks acceptable.
よくある質問
