ISO Drawing Problem

Hello After having opened a lens file I sometimes want to check one or the other ISO drawing, which had been created with this file in the past. I proceed as follows: in the GENERAL Tab I click LOAD, select the ISO drawing of interest and after it has opened I click APPLY. Most of the tolerances appear correct but the shape of the lens not. OK, then I go to the GENERAL tab again and select the correct start surface for that lens. Now the shape looks better BUT - the 2nd radius of curvature flipped from plus to minus. So I now have a plano-concave instead of a plano-convex lens... Of course, this can be corrected by applying "Reset from LDE" but now my manually defined AR coating for that surface, which was not input in LDE, disappears...Manually defined coating was also the reason for unclicking "Automatic" in the associated surface tab. Anybody with similar experience? Best regards, Dusan

The Universal Plot does not consider TCE values in the Lens Data Editor

I've setup a Universal Plot to display the variation of ensquared energy (DENC Merit Function operand) with the temperature (TEMP Multi-Configuration operand). At first glance, the plot looked convincing. However, when I changed the TCE of one surface, the plot did not changed even slightly. Therefore, I think that the TCE is not accounted in the Universal Plot. Could you confirm?

How to reset/adjust the window layout

OpticStudio uses a layout manager to determines how to position and resize the windows. This manager can sometimes go into a state where the window of an editor/analysis take a default undesirable shape. This thread idea has been suggested and co-written by Dusan Zadravec.

How can I create a toroidal surface in X?

When I want to create a toroidal surface, I only see the ability to create the toroid in Y, but I want it along X. How can I do that?

Can OpticStudio be used to model any portion of the electromagnetic spectrum?

Although OpticStudio is well known for modeling visible, infrared, and ultraviolet applications, but is it accurate when using radio, x-ray, or other "non-optical" wavelengths?

Should I use Planar or Spherical Reference when using Huygens for single-mode fiber coupling

This is a frequently asked question. To answer this question, let's slightly discuss how spherical reference works.When calculating Huygens PSF with Spherical Reference, OpticStudio will first trace rays to image surface and then "go back" to exit pupil like below.Then each ray interception point on the exit pupil will be considered as point source that radiate spherical waves and interfere on the image plane. This is called spherical reference.On the other hand, when in planar reference, each ray is simply considered as a plane wave and still interfere on the image plane, which is same as spherical reference.The difference of the two methods will mainly be large when the Huygens PSF is supposed be large. OpticStudio will detect this by checking the distance from exit pupil to image surface and the expected size of the PSF.Back to the discussion about which reference we should use. Usually, we can let OpticStudio decides automatically. However, there are some cases that the spherical r

Tolerancing- On which field of view did the tolerance calculation based ?

I'm running a sensitvity tolerancing analysis, with the option Separate Fields/Configs unchecked. My question is on which field of view did the analysing result based?  And what's the difference between check and uncheck this option?

Where is the nominal criterion value in my tolerance output coming from?

Why is the nominal criterion value different from my Merit Function value in some cases? Is there a different analysis feature in OpticStudio that the nominal criterion is supposed to match up to? If not, then how is it being computed?

How is radiant intensity defined?

The Help file defines Radiant Intensity as “The incoherent intensity of the ray in cosine space (Radiant Intensity) This is the sum of the ray intensity divided by the solid angle subtended by the pixel." The question I have is how this solid angle subtended by the pixel is defined?
