What to Do if the Graphics Windows in OpticStudio are Black or Blank

OpticStudio makes use of advanced graphics cards. If your system does not include an advanced card or if it configured incorrectly, graphics windows in OpticStudio might display a black or empty white field. We've listed fixes and workarounds for the problem below.

Setting OpticStudio to use an advanced graphics card

OpticStudio can make use of advanced graphics cards.  Many modern computers have two graphics cards: an Intel version that’s part of the motherboard, and an add-on card that’s often an AMD or NVIDIA brand. OpticStudio may not default to the most advanced graphics card available due to the Switchable Graphics settings.  In the article below, we’ll show you how to find, update, and configure your card so that OpticStudio can make use of it.

Impact of drawing resolution on ray tracing

Most of the time, the default drawing resolution of native objects in a non-sequential system is enough for providing a good “first guess” as to the location of the ray-object intercept points to be used during ray-tracing. However there might be cases where the drawing resolution needs to be increased by the user in order to get consistent results from a ray trace

How to apply scattering in the presence of total internal reflection (TIR)

In OpticStudio, total internal reflection (TIR) is applied at a surfacebefore other surface properties, such as scattering. This can cause a problem when attempting to model light pipes or fibers that include optically rough surfaces. Such elements rely on TIR, but don’t achieve perfect TIR behavior due to the surface roughness.  To correctly model such systems, an embedded surface can be used so that the scatter function is applied before the TIR.

How to Pivot Any Element About Any Point in Space

The coordinate breaks in OpticStudio are extremely flexible. Coordinate breaks can be used to tilt or decenter any optical surface, or group of optical surfaces, about any pivot point, without disturbing the rest of the optical system.
 
In this article, I’ll show how to tilt a lens about its front vertex without disturbing the rest of the optical system. I’ll also use global coordinates to check that the system remains undisturbed. Then I’ll move on to tilting a lens about its center, and finally I’ll demonstrate tilting a lens about an arbitrary point in space.
