Viewing angle performance evaluation is an important optical testing item. To meet the demand for rapid viewing angle analysis of products, Fstar has launched the Rapid Viewing Angle Tester: Conometer 160MS. It eliminates cumbersome measurement procedures and the requirement for large space, and is applicable to various scenarios such as laboratories and quality inspection.

Fstar has applied for a design patent for the conoscopic lens. The angular distribution of luminance and chrominance of the display screen under test within a ±80° viewing angle can be accurately obtained through a single imaging measurement.

Typically, it only takes about 35 seconds to complete the full viewing angle test of display screens with a luminance of over 100 cd/m², and generate test reports at an interval of 1° or 0.1°. Compared with the method of acquiring viewing angle data by rotating the spectrometer or the display screen, the adoption of the conoscopic lens greatly improves the test efficiency and shortens the test time.

Features

• High Speed

  
  

  The incident angle and azimuth angle of the full viewing cone are equipped with high resolution, and the measurement of luminance and chrominance can be completed within 35 seconds.

  
  

• High Precision

  
  

  Each instrument complies with strict manufacturing and calibration procedures. Every CCD sensor is calibrated to ensure the accuracy of the test.

  
  

• High Efficiency

  
  

  By the reasonable distribution of the optical power of each lens, it solves the linear distribution of illuminance under large field of view and high frame, and improves the light collection efficiency at large angles.

  
  

• High Reliability

  
  

  Adopting advanced optical lens design, it reduces the polarization of direct light and derivative light. It follows strict processing procedures and quality control standards, and has passed a series of calibration procedures.
