注意 ▶凹レンズは単独では光を集めることも、実像を結ばせることもできません。凸レンズと組み合わせてご使用ください。
▶球面平凹レンズには色収差があり、波長によって焦点距離が変わってきます。各波長ごとの焦点距離は[技術データ]の『焦点距離の波長特性データ』をご覧ください。
▶平凹レンズには光を入れる向きがあります。凹面側から平行光を入射させてください。逆にすると球面収差が大きくなり、光学系の光学性能が悪くなる可能性があります。
▶高エネルギのパルスレーザを使用する場合は凹面の反射光によって光路上に集光点を結び、スパークが発生する可能性があります。パルスレーザでご使用される場合に限っては、平面側からレーザー光を入射させてご使用ください。
▶ノーコート品はレンズの表面と裏面の反射による損失で、透過率が90%程度になります。
▶凹面の外周稜線には面取りが施されています。このため設計上のコバ厚(te)より小さくなる場合があります。裏面の平面側を基準面としてご使用ください。

Guide ▶外径サイズや焦点距離など、カタログ掲載品以外の製作も承ります。
▶ノーコートのレンズに特定波長の反射防止膜コートを付けたものの製作も承ります。
