遷移波長・反射帯域・透過帯域・入射角・基板サイズでダイクロイックミラーを比較。蛍光・レーザーシステムでチャンネルを分割・合成するコンポーネントです。
まず入射角を確認してください。多くのビームスプリッターレイアウトでは通常 45 度です。次に反射帯域と透過帯域を励起・蛍光経路に合わせ、偏光・基板厚さ・コーティング面方向を確認します。
これらのダイクロイックミラー(ビームスプリッター)は 45° 入射角で設計され、波長ごとに光を分離します。蛍光顕微鏡・レーザービーム合成・マルチチャンネルイメージング・プロジェクター用途に適しています。ロングパスタイプのダイクロイックは長波長側を透過し、短波長側を反射します。

Dichroic performance changes with angle of incidence and polarization. Confirm AOI before comparing cut-on or reflection bands.
A useful dichroic choice must satisfy both sides of the split: high reflection for one band and high transmission for the other.
For fluorescence, match the dichroic edge to excitation and emission filters as a set, not as an isolated mirror.
It reflects one wavelength range and transmits another, allowing optical systems to split or combine channels by wavelength.
The transition edge shifts with angle and polarization, so the specified AOI must match the instrument design.
Yes. Custom transition wavelengths, reflection/transmission bands, substrate sizes, and AOI targets can be specified.
