Filtros ópticos IR para NIR, SWIR, MWIR y LWIR

Q: ¿Qué regiones IR están cubiertas?

La página cubre necesidades de filtros en infrarrojo cercano, infrarrojo de onda corta, infrarrojo de onda media e infrarrojo de onda larga donde hay datos disponibles.

Q: ¿Por qué importa el sustrato en los filtros IR?

Los materiales de sustrato tienen diferentes rangos de transmisión, por lo que el material debe soportar la banda de longitud de onda infrarroja objetivo.

Q: ¿Se pueden personalizar los filtros IR?

Sí. Se pueden consultar bandas de longitud de onda, tamaños, opciones de sustrato y recubrimientos personalizados para sistemas infrarrojos.

Explore filtros IR para NIR, SWIR, MWIR y LWIR por región espectral, sustrato, banda de recubrimiento y tipo. Compare especificaciones antes de seleccionar filtros para imagen térmica, detección de gases o espectroscopía infrarroja.

Cómo elegir

Elija primero por región infrarroja, luego confirme sensibilidad del detector, transmisión del sustrato, banda de recubrimiento, exposición ambiental y requisitos de montaje. Los filtros IR suelen necesitar opciones de material diferentes a las de los filtros visibles.

Filtros IR

Los filtros IR OPTOStokes cubren aplicaciones de infrarrojo cercano (750-1100nm), infrarrojo de onda corta (SWIR 1,1-2,5µm), infrarrojo de onda media (MWIR 3-5µm) e infrarrojo de onda larga (LWIR 8-14µm). Los filtros paso banda y paso largo IR de esta sección sirven a cámaras de imagen térmica, espectroscopía IR, detección de gases y sistemas de comunicación infrarroja.

Notas técnicas relacionadas

NIR, SWIR, MWIR y LWIR son espacios de diseño diferentes

IR filters should be matched to detector material, substrate transmission, and working temperature. Do not treat all IR bands as interchangeable.

Restricciones de sustrato y recubrimiento

Material choice can limit usable wavelength range before coating performance is considered. Confirm substrate first for IR applications.

Imagen térmica y sensores

For thermal or gas-sensing work, specify the target absorption band, blocking range, and operating environment.

Preguntas frecuentes

¿Qué regiones IR están cubiertas?

The page covers near infrared, short-wave infrared, mid-wave infrared, and long-wave infrared filter needs where data is available.

¿Por qué importa el sustrato en los filtros IR?

Substrate materials have different transmission ranges, so the material must support the target infrared wavelength band.

¿Se pueden personalizar los filtros IR?

Yes. Custom wavelength bands, sizes, substrate choices, and coating targets can be discussed for infrared systems.
