An optical component for directly measuring an original valence state, an original form and an original phase state of liquid in real time, comprising:

• a Programmable Logic Controller (PLC) control module, a monochromatic light purification module, a light intensity control module, a sensitivity adjustment module, and a multi-species perception module;
• wherein the monochromatic light purification module comprises a power switch, a power adapter, a multi-wavelength and multi-light-intensity light source, and a multi-wavelength and multi-stage filter wheel;
• the power switch and the power adapter are configured to convert 220V alternating current into 5V/2 A direct current, and supply power to the multi-wavelength and multi-light-intensity light source;
• the multi-wavelength and multi-light-intensity light source is configured to emit composite light;
• the multi-wavelength and multi-stage filter wheel comprises two light filter discs, light filters, and a servo motor;
• circular holes are disposed on each light filter disc, and a number of the circular holes is not less than 2;
• the light filters are installed in the circular holes, and the light filters in different circular holes have different central wavelengths and different spectral linewidths;
• there are two light filter discs in total, the circular holes in one of the two light filter discs are in a one-to-one correspondence to and are overlapped with the circular holes in another one of the two light filter discs, and the light filters installed in two overlapped circular holes have different central wavelengths and different spectral linewidths;
• the composite light emitted by the multi-wavelength and multi-light-intensity light source sequentially passes through two light filters in the circular holes of the multi-wavelength and multi-stage filter wheel to become monochromatic light;
• the two light filter discs are fixedly connected to the servo motor as a whole;
• driven by the servo motor, the two light filter discs move circumferentially around a central axis of the two light filter discs, so that different circular holes and light filters move to a front of the composite light for filtering to obtain monochromatic lights with different central wavelengths;
• incident light intensity of the monochromatic light is defined as I0, light absorption intensity absorbed by a target species is defined as Ia, and transmission intensity transmitted from the target species to the multi-species perception module is defined as such that It, I0=Ia+It holds true;
• the light intensity control module comprises a power/current continuously adjustable regulator;
• the PLC control module changes I0 of the monochromatic light by adjusting the power/current continuously adjustable regulator, and meets the following conditions:
• when a concentration of the target species changes between a minimum value and a maximum value, after the monochromatic light is absorbed and attenuated by the target species, the multi-species perception module is still able to receive a signal of the monochromatic light, such that It>0 holds true;
• the sensitivity adjustment module is formed by combining flow cells with different optical paths, and adjusts different optical paths based on different concentrations of the target species;
• when the concentration of the target species is larger than a maximum concentration, an optical path is decreased, so that a total number of the target species is decreased;
• when the concentration of the target species is smaller than a minimum concentration, the optical path is increased, so that the total number of the target species is increased;
• the monochromatic light received by the multi-species perception module meets the following conditions:
• (1) under different concentrations, light absorption sensitivity ΔIa of the target species is a maximum;
• (2) when the target species has the maximum concentration, the multi-species perception module is able to receive a signal of the monochromatic light absorbed and attenuated by the target species, such that It>0 holds true;
• (3) when the target species has the minimum concentration, the monochromatic light received by the multi-species perception module is attenuated, such that I0>It>0 holds true;
• and
• the multi-species perception module comprises an optoelectronic receiver and a signal amplifier and is configured to receive monochromatic lights with different central wavelengths corresponding to different target species, and transmission intensities It under different incident intensities and different optical paths corresponding to different concentrations, convert a received light signal into an electrical signal, amplify the electrical signal, and feed back amplified electrical signal to the PLC control module in real time.
