Product Details
The solar blind filter uses the characteristics of ozone in the Atmosphere of Earth to
At 280nm, there will be strong absorption and scattering effects, so 200nm-280nm (referred to as "day blindness
The band "is almost impossible to reach the surface of the Earth. So many research institutions focus on ultraviolet imaging detection
The technology of ultraviolet imaging detection has the advantages of low background noise, low false alarm rate, strong concealment, and structural features
The advantages of simplicity and versatility. The application of solar blind filters for ultraviolet radiation under sunlight intensity
Detection of weak external signals. The sun blind filter has good performance and high transmittance in the transmission band
Rate, with a sufficiently deep cutoff rate in both visible and near-infrared bands.
At present, day blind filters are widely used in optical applications, and they should
Used in fields such as power lines, corona detection, high-voltage equipment corona discharge detection, and forest protection
Fire detection, remote sensing detection equipment, atmospheric environment research, ultraviolet imaging, and space-based ultraviolet bands
Early warning, guidance, ultraviolet communication, biochemical analysis, biomedical analysis, public security reconnaissance, and many more
The field has great commercial and military application value.
What is the solar blind band?
The solar blind band was discovered in the 1950s by scientists in wavelengths less than 285nm
During the process of penetrating the atmosphere and reaching sea level, the sunlight is almost completely absorbed by the ozone layer,
This results in almost no detection of sunlight in this band from sea level to an altitude of 20km,
Therefore, people refer to this band as the solar blind ultraviolet band.
