Imaging tester

Imageability is one of the important optical indicators of materials, which characterizes the imaging ability or distortion degree of materials. It is widely used in quality control management of industries such as automotive metal paint, paint coatings, optical film screens, etc.

Imaging testerMeasuring the imaging properties of materialsSpecialized instruments for clarity, clarity, and image quality, throughMeasure the maximum luminous flux M and minimum luminous flux m of the sample, and combine them with the clarity calculation formula to represent the imaging properties of the material in the form of data.

1. Imaging calculation method

The letter C is the first letter of imaging Clarity, and we use C% to represent imaging ability. The higher the C% value, the better the clarity and the stronger the imaging ability.

Calculation formula: C%=(M-m)/(M+m) * 100%

Where M and m represent the maximum and minimum light flux through the moving grating.

2. Imageability and haze transmittance

There is no linear, proportional, or differential trend relationship between imaging, haze, or transmittance, and there is no corresponding trend relationship between haze and transmittance. Imaging, haze, and transmittance are three independent and unrelated optical indicators.

There is a significant difference in imaging performance between two glass pieces with similar haze and transmittance when placed on the same background image.

The principles and methods of imaging, haze, and transmittance are different. Haze focuses on relative scattered light flux, transmittance focuses on relative parallel light flux and relative scattered light flux, while imaging focuses on absolute parallel transmitted light flux.

The requirements and measuring instruments for imaging and haze transmittance standards are also different, and imaging is usedImaging testerThe haze transmittance is measured using a transmittance haze meter.

3. Structural components of imaging detection instruments

Imaging detection instruments are usually composed of components such as light source, light source slit, grating, photoelectric receiver, photoelectric converter, etc.

Grating is an important component for imaging detection, with the maximum reflected (transmitted) light flux and minimumReflected (transmitted) light flux is obtained through grating movement.
