    <div class="sphx-glr-thumbcontainer" tooltip="Absorbance is exactly linear in concentration by the ideal Beer-Lambert law. A small amount of instrumental stray light (light that reaches the detector without having passed through the fully absorbing sample path) causes the apparent absorbance to fall increasingly below the true value as concentration -- and hence true absorbance -- increases, the classic &quot;rolling over&quot; deviation seen in real UV-Vis instruments.">
