Equilibrio entre brillo y fuga de luz
A wider emission band can improve signal, but it may also collect unwanted fluorescence from nearby channels. Start from the fluorophore spectrum and detector sensitivity.

Cómo elegir
Elija primero el fluoróforo, luego verifique si las bandas de paso de excitación y emisión se ajustan al espectro del colorante y la fuente de luz. Confirme la transición dicroica, el tamaño del portador del microscopio, el espesor del filtro y si los canales vecinos necesitan bloqueo más estricto.

Notas técnicas relacionadas
Notas de selección DAPI, FITC, TRITC y CY5
Common microscope filter sets should be checked against the light source, camera response, and dichroic transition rather than dye name alone.
Por qué importa la posición del borde dicroico
A dichroic transition that is too close to the emission band can reduce useful signal or increase channel leakage in multi-color imaging.
Preguntas frecuentes
¿Qué incluye un juego de filtros de fluorescencia?
This catalog page lists individual excitation and emission filters by fluorophore. A complete microscope configuration may add a matched dichroic mirror selected separately for the instrument and optical path.
¿Puedo reemplazar filtros en un cubo de microscopio existente?
Often yes, if diameter, thickness, and optical orientation match the holder. Confirm mechanical dimensions before ordering.
¿Qué fluoróforos están cubiertos?
The page covers common channels such as DAPI, FITC, EGFP, TRITC, PE, CY5, and related microscopy dyes.
