Technical document of the Department of Biotechnology Testing and Certification of the University. This calibration system is mainly initiated by China Testing Technology Research Institute Hexikia 35G2036-8u Weak light photometer calibration system, which is used for the calibration of strong light curtain products, and defines the national benchmark purpose of [photometer year ()], including the basic basic mathematical parameters to correct the process of transferring light unit values ​​to work products, and specifies its uncertainty, tolerance and basic calibration factors. In order to ensure the consistency and consistency of the test light value and the fixed light value, the system of weak light is balanced with the strong light system in a wider range. It is a metrological standard instrument.
1 Weak light illuminator - a group of excellent performance (> cans of optical instruments and (travel optical standard operation has been created, according to the new definition of luminous intensity unit software W: when the national photometric standard one ... electrical calibration radiometer with the help of commercial Lu line and calibration certificate photoelectric two false penetration let the unique surface say weak light group unit, the material optical machine standard detector group is used to save the light illumination information and directly and the micro-light test station to limit the retrograde virtual value, 2 base detector group illumination and material quantity range

3 Weak light illumination standard within -·A set of selected BDQ1, BDQ2 lighting environment standard special light boxes and a series of external parts with concentrated light sheets are combined with the standard light source of the leopard feather light. Each set of lamps must be 6. The light source of the labor light standard is certified by the national light supply stock. The color quality of the 3.1U02 lamp is 2856, the maximum range of illuminance is 1G~10, the total power is 1x=3%, and the current illuminance system is available. The color quality of the 32BDO1 lamp is ? 652, the range of illuminance is ~ heart-, the total power is increased by 4%, and the light quality system is slightly improved. 22

3, 3 for the illuminance standard, other devices can be used. The uncertainty of the reflection rate is 1.5% (other standard meters are reported in 11. The standard brightness is 1~10-*ed/m, the total uncertainty is 4%; the standard brightness is 10\1~10-ad/m2, the total uncertainty is 4.5%2. The special color is supported by the light photometric method. The three working instruments are ink. The weak light meter is divided into two levels, the first one is 110-1x, the dark measurement range is 16-1~10 x, the recording is difficult to identify +A±4, the second weak light meter can use 1~10-11, the visual measurement cell uses 10-+～10-01x, the indication value is allowed to be installed ±=7%
to obtain the original standard light, and it is also calibrated on the weak light test bench according to the mountain accumulated light standard
. 6. The weak light degree is divided into two levels:
Extremely weak light degree is used for vision benefit door 11m, visual measurement range 10-*~10-/m, the allowable error is: ±5% Secondary weak light degree gauge free measurement range 1~10/m, visual width measurement range 10-1~10-\d/m*. The allowable error is 4%. The weak light meter is used for light measurement in your car, and the true light is used as the benchmark for micro-light measurement on the test bench: the system is not suitable for the determination of the signal history of the kidney.
