エッジ急峻性と遷移幅
Longpass and shortpass filters are often selected by edge position, but transition width and blocking depth determine real system performance.
ロングパス・ショートパスエッジフィルター
波長領域を分離するロングパス・ショートパスエッジフィルターを確認。カットオン/カットオフエッジ・遷移急峻性・遮光範囲・透過率・物理サイズを比較してください。

選び方
長波長を透過し短波長を遮光する場合はロングパスフィルター、逆の場合はショートパスフィルターを使用してください。エッジ波長・遷移スロープ・遮光範囲・入射角・バンドパスフィルターとの併用の有無を確認します。

ロングパス・ショートパスフィルター
OPTOStokes ロングパス・ショートパスフィルターは、蛍光顕微鏡・ラマン分光・光学機器における波長分離のためのシャープなエッジ遷移を提供します。ロングパスフィルターはカットオンより長波長を透過し短波長を遮光し、ショートパスフィルターはその逆の動作をします。精密なスペクトル選択性が必要な場合、バンドパスフィルターとの組み合わせに最適です。

関連技術資料
エッジフィルターの組み合わせ
A longpass and shortpass pair can define a custom passband when a standard bandpass option is not available.
検出器保護
Use edge filters to suppress unwanted source energy before it reaches sensitive detectors, especially in broadband or high-power systems.
よくある質問
ロングパスとショートパスフィルターの違いは？
A longpass filter transmits wavelengths longer than its edge; a shortpass filter transmits wavelengths shorter than its edge.
カットオン・カットオフ波長とは？
It is the edge wavelength where the filter transitions between blocking and transmission.
エッジフィルターとバンドパスフィルターは組み合わせられますか？
Yes. Edge filters are often combined with bandpass filters to improve blocking or shape a more specific spectral window.
