 Light Source: 

  • Monochromatic Light Source: GAO Tek’s polarimeters typically use a monochromatic light source, often produced by a sodium lamp or LED, to ensure a specific wavelength. 

Polarizer: 

  • Polarizing Filter: A component in GAO Tek’s polarimeters that produces plane-polarized light by allowing light waves oscillating in a specific direction to pass through. 

Sample Chamber: 

  • Sample Tube: A transparent tube or cell in GAO Tek’s polarimeters where the substance to be Analyzed is placed, allowing the polarized light to pass through the sample. 

Analyzing Unit: 

  • Analyzer: Another polarizing filter in GAO Tek’s polarimeters that can be rotated to analyze the rotation of the plane of polarized light after passing through the sample. 

Detector: 

  • Photodetector: In GAO Tek’s polarimeters, this component converts the intensity of light into an electrical signal, providing a measurement of the amount of light that passes through the sample. 

Electronic Control Unit: 

  • Microcontroller or Microprocessor: electronic control unit manages the overall operation of the polarimeter. 
  • Motor Control: Controls the rotation of the analyzer in GAO Tek’s polarimeters, allowing precise control of the angle. 

Display and User Interface: 

  • Display Panel: Shows measurement values, calibration information, and other relevant data on GAO Tek’s polarimeters. 
  • User Interface: Keypad, touchscreen, or buttons in our devices for user input and calibration adjustments. 

Calibration System: 

  • Calibration Standards: Known optical rotation standards used for calibrating and verifying the accuracy of GAO Tek’s polarimeters. 

Temperature Control: 

  • Peltier Element or Thermostat: Maintains a constant temperature within the sample chamber of GAO Tek’s polarimeters, as optical rotation can be temperature sensitive. 

Software: 

  • Data Processing Software: Analyzes the collected data in GAO Tek’s polarimeters, compensates for temperature effects, and calculates the specific rotation or concentration of the optically active substance. 
  • User Interface Software: Allows users of GAO Tek’s polarimeters to interact with the device, set parameters, and view results. 

Data Logging and Connectivity: 

  • Data Output Ports: USB, RS-232, or other interfaces on GAO Tek’s polarimeters for transferring data to external devices or computer systems. 
  • Data Logging Capability: Some GAO Tek polarimeters have built-in memory or the ability to connect to external data loggers for storing measurement data. 

Light Modulation: 

  • Modulator: Some advanced polarimeters use a modulator to modulate the light before it passes through the sample, enabling the measurement of circular dichroism. 

Automatic Measurement Systems: 

  • Automated Sample Loading: Systems in GAO Tek’s polarimeters that can automatically load and analyze samples, improving efficiency and reducing manual handling errors. 

Adjustable Aperture: 

  • Aperture Control: Allows users of GAO Tek’s polarimeters to adjust the size of the aperture, accommodating different sample volumes and optimizing light intensity.Â
