Hi Mr or Miss  Mojtaba

 Firstly, sorry for being unsure with your title.

 I am really interested in this webinar’s topic. I have several questions about spectrometer.

1. is it meaningful or useful to evaluate MTF of a spectrometer if it is used as a imaging part?
2. in this passage, https://support.zemax.com/hc/en-us/articles/1500005578862-How-to-build-a-spectrometer-implementation, it introduces the method to design a spectrometer, and as far as i understand, 1)spectral resolution 2) enclosed energy(Y) are necessary to evaluate, just wonder any other parameter or content needs to pay attention when a spectrometer is being designed? 

Best regards

Q: Does OpticsBuilder only work with CREO?   I seem to remember that there was a product that integrated with SolidWorks.

A: OpticsBuilder only works with Creo at this time. As a result of Dassault Systems’ recent decision to conclude Zemax’s membership in the SolidWorks partner program, Zemax is no longer able to support our OpticsBuilder for SolidWorks product. Effective December 31, 2021, SOLIDWORKS integrations with Zemax products were deprecated.

Q: hello, Is this chat box meant for Q & A? 

A: Hello,

In this thread, we answer the questions we didn’t get to during the live event. If you have any questions, please feel free to send it here.

Q: Are there OpticsBuilder interfaces to CAD applications other than CREO (e.g., SolidWorks, Inventor, OnShape, etc.)?

A: OpticsBuilder only works with Creo at this time. As a result of Dassault Systems’ recent decision to conclude Zemax’s membership in the SolidWorks partner program, Zemax is no longer able to support our OpticsBuilder for SolidWorks product. However, Zemax team is currently working to support OpticsBuilder on other CAD platforms in the near future.

Q: Dr Raj Bahadur Yadav from India

A: Hi Raj, Thanks for attending this webinar. It sounds like we missed your question. Please feel free to send it here if you have any questions.

Hi Yang,

Thank you for sending in your question and my apologies for the late response.

Since sending a reply right under your question was not possible I just post a reply here.

In terms of spectral resolution we need to take the limitations imposed by diffraction and by the pixels size of the detector being a line camera into consideration. OpticStudio offers a very convenient way to check these limitations in the Huygens PSF Cross Section plot, that is why we looked into point spread function. The process relies mostly on the Knowledgebase article: Resolution of diffraction-limited imaging systems using the point spread function – Knowledgebase (zemax.com)

At the end of the day, the resolution of our spectrometer is limited by the pixel size of the line camera and not by diffraction. MTF is commonly used to describe the performance of an imaging system, but the finite resolution of the detection system is often ignored. If you have a specific design criteria based on MTF data you may still account for detector pixel sizes in OptoicStudio using partially coherent image analysis feature. This knowledgebase article describes how to give a full-system MTF measurement given the pixels size: How to include detector resolution in MTF calculations – Knowledgebase (zemax.com)

Finally, to touch diffraction limited spot sizes in the spectrometer there are a variety of the parameters including airy disk and encircled energy to be targeted. you may find useful discussion in this regard in this knowledgebase article: How to build a spectrometer - theory – Knowledgebase (zemax.com)

I hope this helps.

hi  Mr Mojtaba,

 Thanks for your detailed explanation, totally understood.

I will refer to the passage you recommended.

Best regards
