The objective of the utility model is to create a compact installation that provides storage and transfer of the unit size of small levels of illumination to photometers in the range of illumination from 10 ^-4 to 10 lux, which can be placed in a laboratory room without additional requirements.

The problem is solved in that the installation for storing and transmitting the size of a unit of illumination includes: an illuminator unit with a set of light measuring lamps, a positioning device with a holder of a light measuring lamp, a power supply and monitoring system for light measuring lamps, a set of precision photometers, a set of recording electrical signals precision photometers, positioning device with interchangeable holders of precision photometers, optical table, automated rail system, optical path alignment system, emission control system for light measuring lamps, personal computer characterized in that the illuminator unit includes: a diffuser plate, a positioning device with interchangeable holders for a diffuser plate, a turret, a disk with calibrated diaphragms, a lightproof shutter, and lightproof the case, the base of the optical table, having a length and a width of not more than 1 m, and a height of not more than 0.2 m is made in the form of a cellular tabletop, which once There is also a vibration-isolating pneumatic system on the base, as well as a general light-tight casing, the automated rail system has a length of 0.6 m, the optical path alignment system contains a laser located on the optical axis after the positioning device with the light-intensity lamp holder, and an adjustment mirror, a control system radiation of light measuring lamps of light intensity contains a precision optical radiation receiver and a multimeter.

The essence of the utility model is illustrated in the drawing, which shows a diagram of the proposed utility model.

The installation comprises a lighter unit 1, which includes: a positioning device 2 with a holder of a light measuring lamp, a set of light measuring lamps of light 3, a laser 4, a positioning device 5 of a holder of a diffusing plate, a diffusing plate 6, an alignment system of the optical path which includes: alignment mirror 7, a system for controlling the radiation of light measuring lamps of luminous intensity, which includes: a precision receiver of optical radiation 8, a positioning device for precision optical radiation receiver 9, a system for recording electrical signals of precision photometers 10, a turret 11, a disk with calibrated apertures 12, a lightproof shutter 13, an automated rail system 14, a positioning device 15 with interchangeable holders of precision photometers, a set of precision photometers 16, a power and control system light bulbs 17, including: a power source 18 and a multimeter 19, a personal computer 20, a general light-tight housing 21 and an optical table 22.

The device operates as follows.

The light intensity measuring lamp 3 is installed in the holder located in the positioning device 2, and the precision photometer 16 in the holder located in the positioning device 15. If necessary, align the optical path, for which an adjustment mirror is installed in the holder placed in the positioning device 5. 7, and behind the bulb of the light-measuring lamp the intensity of light is laser 4.

The positioning device 5 is designed so that the working surface of the alignment mirror is at an angle of 45 ° relative to the incident beam of radiation generated by the laser. In this position, the radiation beam reflected from the working surface of the alignment mirror 7 falls into the center of the input diaphragm of a precision or tested photometer.

Install in the holder located in the positioning device 5, the diffuser plate 6. Measure the distance l _1n in meters between the filament of the lamp and the center of the reflective plate. A precision photometer is mounted in a holder located in the positioning device 14. Measure the distance l _2n in meters between the calibrated aperture in the disk 11 and the photosensitive surface of the precision photometer. Turn on the personal computer 19 and download the measurement program. After downloading the program, a survey of individual installation nodes and ports of the personal computer on readiness for work is sequentially performed. If the test passed without errors, a message is generated about the readiness of the registration system and the program enters the configuration mode.

Using specially developed software (software), the displacement step size and the number of steps in the longitudinal direction of the automated rail system 13 are calculated in accordance with the specified illumination ranges and the step within the specified illumination ranges.

Using the power system and control of the measuring lamps 17, the voltage and current are set on the measuring lamp at which its spectral distribution of the radiation power corresponds to a standard “A” type MCO radiation source.

During the measurements, the signal Y _sd corresponding to the signal obtained with a precision photometer or a tested photometer is recorded when the light beam is interrupted by an opaque shutter 12 and the signal Y _s corresponding to a signal obtained with a precision photometer or a tested photometer with free passage of the light beam. The difference Δ is calculated by the formula Δ = Y _s -Y _sd , which corresponds to the value of illumination at points of a given range. Information sources:
