77mm 720nm Infrared X-Ray Infra-Red IR Pass Filter 77mm-720nm

 

IR filter can be used for improving visibility through certain kinds of fog or haze. This property is particularly important for long-distance photography on the ground where the detail of distant objects is often obscured by haze. It is also useful for high altitude, and especially oblique photography from the air like when landing an airplane in a foggy airport.
