Hello everybody,the problem I have has been known to me for some time, but now I am trying to analyze a bulk scatter material. The analysis returns a spike at 0 ° which does not allow me to have a reliable graph. Someone solved the problem with settings or settings.I have already tried to use a surface detector (but it does not satisfy me) but I would like to use a polar detector anyway. Thanks a lot.
I am modeling some CPC’s in NSC. I know that they are not 100% reflective and I want to assign a coating to the inside surfaces. But in OS, NSC, there is no way to apply a coating to a surface. Why is this? I can think of many reasons I would want a surface with a coating. A simple cubed beam splitter is one example. Define a cube of glass and then put a 45 degree surface inside with a 50/50 coating. Or, make CPC’s objects rather than surfaces. Anyone have any thoughts to a workaround?Thanks,Paul
HI community!Actually i was going through the THOR Lab manual for FTIR spectroscopy and got stuck at understanding the relationship between resolution expressed in wavenumbers (R cm^1-) and in nanometer (R(nm). In the Table-2 (link given below) of that manual, can someone explains the conversion formulae used for calculation ? FTIR document reference
Dear community,as part of my bachelor thesis, I’m trying to find a solution to compensate the refraction of a glass cylinder. I’m afraid, I don’t have sufficient time to gain enough skills on the program although I already did many of the tutorials.During my literature research, I found out, that a pair of mirror-symmetric meniscus lenses should solve my problem. I tried to optimize my model of the optical system (see file), but several tries did not work. :-(I really appreciate your help!Thank you,Elias
Hi all, I am trying to export the lens in the attached file to cad file(step).I got an error for surface no. 4 -failed to export.When increasing the clear diameter of the surface to be the same as the mechanical diameter, there is no problem. Thanks,Nadav
Hello,When using objects as sources it would be very useful to normalize the power to the surface area of the object. A good example of where this is useful is for blackbody sources where the intensity per surface area is well known.Internally Zemax must be calculating the surface area when doing the raytrace in order to distribute the rays evenly.Is it possible to have access to this information?Has someone already created a macro to do this for generic objects?thanks,Ross
Hi, I am wondering how to include Fresnel reflection in a simple non sequential model : I have a pipe from which I am entering with light from the side. In order to verify if Optic Studio already models reflection at the air-glass interface, I have placed a detector before and after the interface. With 1 W source power I get the same on the second detector, both for normal incident light and light tilted at an angle. This makes me think reflection is not taken into consideration here. On the other hand, if I check the transmission vs angle plot I can see transmission is computed correctly:Why is detector 2 then not giving a total power of 0.96 W at 0 incident angle? How can I model it in a way I have this information on my detector? I have tried to tock the reflection option for the front face of the object, but this results in a mirror like behavior, which is not right either: Thank you to whoever will answer me!Giulia.
I’m creating a modeling system in SC of the human eye with a lens in front of it. The rays of the system are coming from different positions in space. I’m trying to rotate the human eye with C.B but I’m ending up with two situations:The eye is rotating except for the retina Only the lens that located in front of the eye is rotatingI even try to add a dummy surface after the retina but it wasn’t helpfulHow can I rotate only the eye?
