Description

Technical Field

[0001] The utility model relates to the technical field of light transmittance detection, in particular to a film transmittance detection device. Background Art

[0002] The background technology of film transmittance tester mainly includes transmittance tester, film online tester, film oxygen permeability meter and haze transmittance tester.

[0003] Light transmittance tester: Mainly used to measure the visible light transmittance of automotive glass, various types of glass, acrylic, film, plastic, and transparent and translucent objects. It is a portable, intelligent digital display light transmittance tester with a sleek and lightweight appearance, fully intelligent design, automatic calibration, a long-life light source, accurate measurement, and good repeatability. Film online detector: Used for real-time quality testing of films, it can detect typical defects such as crystal points, black spots, mosquitoes, stains, lines, holes, etc., and has functions such as automatic sound and light alarms, screenshots of current defects, and real-time X / Y coordinate defect distribution map display. Its detection speed can reach 800m / min, and the detection width can be customized according to the production line. Film oxygen permeability meter: Includes isobaric oxygen permeability meter and differential pressure oxygen permeability meter, which use different testing principles to measure the oxygen permeability rate of films. Isobaric oxygen permeability meters calculate oxygen transmission rate by evacuating both sides of the sample and then introducing oxygen. The rate of pressure increase in the low-pressure chamber is then measured. Differential pressure oxygen permeability meters, on the other hand, calculate the oxygen transmission rate by calculating the pressure difference. Haze and light transmittance testers are widely used in laboratories, factories, and on-site operations, providing high-precision optical performance evaluation. They assess a material's haze and light transmittance by measuring the proportion of scattered light. They comply with multiple international and domestic standards, offer rapid testing efficiency, and employ multiple measurement modes, making them suitable for testing a wide range of samples. The development of these testing instruments and technologies has provided diverse solutions for thin film material transmittance and quality testing, meeting the diverse performance requirements of various fields. Prior art, relatively lightweight light transmittance testers like the LS116 model have certain drawbacks. The controller requires a separate support frame and lacks self-supporting capabilities. The detection module cannot be clamped and secured to the object being tested, requiring manual support, which can lead to errors in light transmittance measurements. Therefore, this paper proposes a new thin film transmittance testing device. Utility Model Content
