Select and Graph Theoretical Optical Filter Data

MyLight, our online filter modeling tool, allows users to very quickly characterize the theoretical spectral behavior of optical filters under different optical conditions. Are you interested in seeing how a Semrock catalog filter behaves under a particular Angle of Incidence (AOI), Cone Half Angle (CHA), and/or Polarization? MyLight can provide you with the theoretical answers by simply entering your parameters and selecting “Generate Plot.” MyLight data can also be downloaded for further analysis and the page can be printed.

Optical filter data are traditionally shown only at standard AOI, zero CHA, and average polarization, i.e., assuming collimated incident light. But what if your system were to use a tilted filter and/or a cone of illumination? What if you were interested in angle tuning a filter to optimize it to your specifications? In the past, you had to contact the manufacturer and wait for an answer. With MyLight, you can input your conditions, click Generate Plot, and immediately evaluate that filter’s theoretical data set.

Designing and evaluating interference optical filters has never been easier with the help of MyLight. And because Semrock filters match their theoretical spectra so closely, you can depend on the results. MyLight puts the power of optical filter modeling and evaluation at your fingertips.

MyLight may be accessed from each filter's specific product page, above the actual measured data spectra; click on the green MyLight box.

An example MyLight graph of the catalog filter LL01-532 at AOI = 40° is shown below; note the polarization dependence.

"Your tool to calculate filter characteristics as function of angle of incidence is very useful. Very nice tool to have. Thanks a lot!"
