The present embodiment structure and the structure of embodiment 1 are essentially identical, and something in common repeats no more, the difference is that:
The present embodiment also discloses deep ultraviolet, visible, near infrared radiometric calibration source device application method, specifically include with
Lower step:
(1) brightness of light-emitting window spoke is calculated:
Light source output spoke is carried out according to xenon short-act lamp light source typical color wyntet's sign according to the formula (1) of Planck blackbody radiation
Penetrate flux calculating.
C1, C2 are Planck's constant in formula, and T is xenon short-act lamp light source color temperature 5800K, relatively with sun colour temperature.
The xenon short-act lamp output radiation Flux Distribution being calculated is as seen in figures 3-6.
(2) integrating sphere light-emitting window analysis of Uniformity:
The uniform spatial distribution of integrating sphere light-emitting window spoke brightness is its important parameter in application, spatially uniform packet
Include at a certain distance from light-emitting window the irradiance uniformity of shadow surface and uniform as the spoke angular brightness on vertex using light-emitting window axle center
Property (corresponding integrating sphere inner surface spoke brightness uniformity i.e. in angular range).Integrating sphere light source one primary light source of youth of approximation,
Surface uniformity can regard the uniformity of its corresponding integrating sphere inner surface spoke brightness as, and corresponding region is as shown in Figure 2.
From figure 2 it can be seen that having included surface uniformity institute in index request ± 25 ° range interior angle uniformity corresponding region
Corresponding region, when angle heterogeneity meets index request less than 1%, surface uniformity, which can equally meet angle uniformity index, to be wanted
It asks.
The integrating sphere inside coating of built-in light source can approximation regard lambert's body as, therefore light-emitting window spatial distribution heterogeneity

The brightness of primary event spoke can be obtained by following formula at tungsten halogen lamp installed position normal counterclockwise angle θ:
Wherein l is integrating sphere interior diameter.
Multiple reflections generate spoke brightness at θ
Point light source radiation scope is hemispherical space on ball wall, therefore exit luminous flux is
φ=F2 π (3)
Spoke luminance non-uniformity is within the scope of point light source θ
It is found that integrating sphere uniform spatial distribution is only with angular range calculated, aperture efficiency, ball wall inner surface reflectivity
Related, in aperture efficiency with one timing of inner-wall material reflectivity, spoke luminance non-uniformity is as shown in Figure 6 with angle change range:
Aperture efficiency is smaller as shown in Figure 6, and inner-wall material reflectivity is higher, and uniformity is better within the scope of light source launch angle,
For 0.8 meter of opening integrating sphere light source, when inside coating reflectivity is 0.97, and aperture efficiency is 0.04, the point light source angle of departure ±
Integrating sphere spoke luminance non-uniformity is corresponded within the scope of 25 ° less than 1%.
