The LS116 light transmittance meter and the LS117 optical density meter have a big difference.Below we distinguish the difference between the measurement material,measurement size, optical path design and measurement principle.

Customers who often buy Linshang instruments can't tell the difference between the LS116 light transmittance meter and the LS117 optical density meter. They feel that these two products are similar, but this is not the case. In this article, we will mainly introduce the difference between the LS116 light transmittance meter and the LS117 optical density meter.

         Model LS116 light transmittance meter LS117 optical density meter
Testing material glass, solar film,transparent and uniform regular transmission materials

Opalescent, fog and frosted materials such as aluminized sheet, X-ray film, film, lens ink

Material size Longer than 10 mm in diameter and thinner than 100 mm in thickness Longer than 2 mm in diameter

Measurement

principle

Transmitted light intensity/incident light intensity OD=log10(incident light/transmitted light) or OD=log10(1/light transmittance)
Optical path  Parallel optical path design Diffuse transmission path with integrating sphere effect

LS117 optical density meter and LS116 light transmittance meter test materials 

Compared with the LS116 light transmittance meter,the LS117 optical density metercan measure not only the transmittance of a diffuse transmission material but also the transmittance and optical density of a low transmittance material.And it has more powerful function.Therefore,the price of the two instruments is also different.The LS116 light transmittance meter cost $292 and the LS117 optical density meter cost $550.The above is the main difference between the LS116 light transmittance meter and the LS117 optical density meter.
