The working principle is as follows: when the device is used, the box body 31 is pulled out of the test box 1, the monochromatic light module 3 is built, and the first reflecting mirror 3302, the collimating mirror 3301, the grating 3305, the second reflecting mirror 3303 and the objective lens 3304 are installed on the installation plate 32; then, carrying out corresponding debugging, specifically: firstly, mounting a first reflector 3302, rotating a locking shaft at the lower part of the first reflector, adjusting the angle of the first reflector 3302, reflecting light entering from an incident slit 34 onto a collimating mirror 3301 after passing through a first reflector lens, and tightening a locking nut to fix the angle; then, the angle of the collimating mirror 3301 is adjusted, and the collimated light is reflected to the grating 3305; then, the grating 3305 and the objective lens 3304 are adjusted, the controller 2 controls the stepping motor 3306 to start, so as to drive the grating 3305 to rotate, and perform wavelength screening, so that the light ray objective lens 3304 with specific wavelength reflects into the second exit slit 36, and is output to the photoelectric detector 37, and the intensity of the light ray is measured by the photoelectric detector 37; finally, after the measurement is completed, the controller 2 controls the second reflecting mirror 3303 to rise, so as to reflect the light into the first exit slit 35, and the light emitted from the first exit slit 35 is used as the test light. And before debugging, adjusting the incident slit 34, the first emergent slit 35 and the second emergent slit 36 according to the test requirement. After the adjustment is completed, the box body 31 is pushed into the test box 1, the box body 31 is positioned through the positioning module, it is ensured that the incident slit 34 is connected with the light pipe, and the first emergent slit 35 corresponds to the light inlet.
The photocell to be detected is placed in the sample card slot 502, a sample is fixed through a plurality of cards on two sides of the sample card slot 502, and then the photocell two-stage is clamped by the conductive clamp 503.
The controller 2 controls the translation electric cylinder 4031 to be started, the translation electric cylinder 4031 pushes the first light source holder 4033 and the second light source holder 4034 to slide on the translation guide rail 4032, so that the first light source 401 and the second light source 402 respectively correspond to the light guide pipes, the cooling fan (4041) is installed above the translation guide rail 4032 and matched with the light guide pipes in the position direction, heat can be dissipated for the first light source 401 or the second light source 402 aligned with the light guide pipes, and the service life of the light sources is guaranteed.
The first light source 401 is a monochromatic light source, the second light source 402 is a white light source, switching can be performed according to the requirement of a test, when the first light source seat 4033 reaches the set position, the controller 2 controls the first push electric cylinder 4035 to extend, the first light source 401 is pushed into the light guide pipe, and the moving distance of the first light source 401 is measured through the second distance sensor 4038.
When a white light source is adopted, the controller 2 controls the stepping motor 3306 to rotate to drive the grating 3305 to rotate, when the grating 3305 rotates, light signals with different wavelengths are sequentially reflected to the objective lens 3304 and focused on the second exit slit 36 through the objective lens 3304, the controller 2 records rotation angle information of the stepping motor 3306, and the photoelectric detector 37 records output light signal radiation power of different wavelengths represented by different angles of rotation angles of the different gratings 3305.
And then, the second reflecting mirror 3303 is lifted, the angle of the second reflecting mirror is adjusted to reflect the light reflected by the objective lens 3304 to the first exit slit 35, and the light emitted from the first exit slit 35 enters the sample box 501 through the light inlet to irradiate the photocell in the sample box 501. The current generated by the photocell after being irradiated by the light with different wavelengths is different, the current intensity output by the photocell is measured by the current detector 601, the light radiation power is measured by the photoelectric detector 37, the human eye vision function table is inquired under the condition of the known wavelength and the light radiation intensity information of the wavelength, the human eye response value is obtained, and the luminous flux (namely the luminous flux with the corresponding wavelength) can be calculated
) The ratio of the current intensity to the luminous flux is the spectral sensitivity of the photovoltaic cell at the corresponding wavelength.
When a monochromatic light source is used, the angle of the grating 3305 is adjusted to adapt to the wavelength of the light source, and since the wavelength and power of the monochromatic light source are known, the spectral sensitivity of the photocell with the corresponding wavelength can be obtained by measuring the current intensity according to the current detector. The measurement value can also be compared and verified with the measurement result at the same wavelength when the white light source is used.
