The densitometer is used to measure the optical density value, which is the ratio logarithm of the incident light to the transmitted light or the reciprocal logarithm of the light transmittance. The haze is the percentage of the transmitted light intensity above the angle of 2.5° from the incident light as a percentage of the total transmitted light. There are essential differences between the two meters.

X-film is mainly divided into black film and yellow film. The Linshang LS117 densitometer is suitable for testing black film but not yellow film. The instrument can measure not only the transmittance value but also the optical density.

The main function of the lampshade is to collect light and diffuse light. For testing the transmittance of lampshade, Linshang LS117 densitometer is the first choice.

Electric lamps have a very broad market in the market. Do you know materials that can be used as lampshades. How to detect the light transmittance of the lampshade?

The optical densitometer (transmission densitometer) is mainly used to detect the optical density value of various materials such as X-ray film, aluminized film, etc.

Ooptical density and light transmittance can be measured by professional transmission densitometer

This article mainly describes how to use the optical density meter LS117 to detect the optical density of various materials such as X-ray film, aluminum film, etc.
