			<title><![CDATA[Quantifying Veiling Glare]]></title>

			<description><![CDATA[Veiling glare is a term that is often used in the field of imaging system design. Technically, veiling glare is stray light that reaches the sensor plane of an imaging system, and it can cause a decrease in the imaging system&#8217;s performance.<br/><br/>Often, &nbsp;a full non-sequential treatment is needed for accurate results. However, for many optical imaging systems, a first-cut look at forward scattering effects is all that is really required. This article will show how to make just such a preliminary veiling glare measurement using tools that are already built into ZEMAX. This analysis will require just a few minutes to perform, and will give very useful results.]]></description>

			<description><![CDATA[In this article, we will create model of a human eye in ZEMAX using the Liou & Brennan 1997 eye model. After successfully generating this eye model in ZEMAX, we will use it to design a free-form progressive eyeglass lens. ]]></description>

			<description><![CDATA[An off-axis parabolic (OAP) mirror consists of a small section cut out&nbsp; from a larger, so-called “parent” parabolic mirror. Working with these mirrors, especially for the first time, can seem like a daunting task.&nbsp; However, with a little instruction and a bit of practice, OAPs can be fairly straightforward to manipulate and very handy to use.<br/><br/>This article describes a real-life assignment that required an OAP to be used with an existing optical system]]></description>
