This test is essential for industries like automotive, packaging, and electronics where the transparency of plastics matters. The test measures total luminous transmittance, which tells you exactly how much visible light can pass through a materialhttps://koala.sh/api/image/v2-wora1-sp8zq.jpg?width=1216&height=832&dream
