Pendiente del borde y anchura de transición
Longpass and shortpass filters are often selected by edge position, but transition width and blocking depth determine real system performance.
Filtros paso largo y paso corto de borde
Compare filtros paso largo y paso corto por longitud de onda de borde, pendiente de transición, rango de bloqueo y transmitancia. Seleccione el filtro de borde adecuado para separación espectral en su instrumento.

Cómo elegir
Use filtros paso largo cuando las longitudes de onda mayores deben pasar y las menores deben bloquearse. Use filtros paso corto para lo inverso. Confirme la longitud de onda del borde, la pendiente de transición, el rango de bloqueo, el AOI y si el filtro se combinará con un filtro paso banda.

Filtros paso largo y paso corto
Los filtros paso largo y paso corto OPTOStokes ofrecen transiciones de borde nítidas para separación espectral en microscopía de fluorescencia, espectroscopía Raman e instrumentación óptica. Los filtros paso largo transmiten longitudes de onda mayores al corte-on mientras bloquean las menores; los filtros paso corto hacen lo inverso. Se combinan bien con filtros paso banda cuando se requiere selectividad espectral precisa.

Notas técnicas relacionadas
Combinación de filtros de borde
A longpass and shortpass pair can define a custom passband when a standard bandpass option is not available.
Protección del detector
Use edge filters to suppress unwanted source energy before it reaches sensitive detectors, especially in broadband or high-power systems.
Preguntas frecuentes
¿Cuál es la diferencia entre filtros paso largo y paso corto?
A longpass filter transmits wavelengths longer than its edge; a shortpass filter transmits wavelengths shorter than its edge.
¿Qué significa longitud de onda de corte-on o corte-off?
It is the edge wavelength where the filter transitions between blocking and transmission.
¿Se pueden combinar filtros de borde con filtros paso banda?
Yes. Edge filters are often combined with bandpass filters to improve blocking or shape a more specific spectral window.
