Based on the test principle of conventional transmittance, micro optical and CCD images are added to accurately locate the test area and the phase / absolute transmittance of the small area of the sample. tested with a small point (0.3 mm). Compared to traditional eyepiece focus, it uses digital camera video for more precise focusing, faster inspection and an adjustable spot aperture size that has reached an unprecedented minimum size, more suitable for better and better samples on the market. It is specially used to detect transmission via mobile phone control panels, IR holes on mobile phones, menu buttons, back buttons and other small areas.
Product advantages:
Small and easy to carry tools; test speed is very fast, 1 second can produce results; Transmission and reflection detection of samples is very small; Excellent wavelength repeatability of 0.1nm; Optical measurement with high accuracy; Minimize stray light.
