Transparency Measurement Of Plastic Sheet And Film
Hazemeters and spectrophotometers are used to measure the level of haze light transmitting and light scattering properties of transparent materials.
Transparency measurement of plastic sheet and film. A newly developed procedure based on the determination of light transmission within a very small angle gives good correlation. 1967 10 01 00 00 00 available methods for testing the transparency of plastic sheet and film have been found inadequate as regards the correlation between measurement and visual observation. Looking to measure the thickness and variability of plastic film. A mil is 1 1000th of an inch.
Haze measures the milkiness of the material film or sheet. All plastics have some degree of light scattering or transmission loss which is usually measured by astm d1003. Plastic sheets and film are polymers that supply material for injection molding machining packaging construction electronics signs and other applications. You can also learn more about measuring plastic film thickness and variability in our article how to measure plastic film.
In solar cell i need to measure the transparency of an anode film and need to draw a plot between transparency and thickness of a film at one particular wavelength. Light transmission property of the plastic films and rigid plastics are quite difficult to measure and define. As per the current terminology the materials comprise with the terms such as clarity total transmittance transparency diffuse transmittance see through resolution distance opacity turbidity haze translucency hiding power etc. Transparency refers to the optical distinctness with which an object can be seen when viewed through plastic film sheet glass etc in the manufacture of sheeting film or glass the quantitative assessment of transparency is just as important as that of haze.
Available methods for testing the transparency of plastic sheet and film have been found inadequate as regards the correlation between measurement and visual observation. Solvetech s unique technology can help per astm d8136. Plastic film is thinner and more flexible than plastic sheets and is often transparent or translucent. A transparency meter also called a clarity meter is an instrument used to measure the transparency of an object.
25 pack clear craft plastic sheets 007 thick crystal transparent film for making art stencils paper size 8 5 x 11 inch 4 7 out of 5 stars 22 19 99 19. 1 1 this test method covers the measurement of the transparency of plastic sheeting in terms of regular transmittance t r although generally applicable to any translucent or transparent material it is principally intended for use with nominally clear and colorless thin sheeting.
