Webinar details

Date: Thursday, June 9th

Time: 6:00 - 7:00 AM PDT | 11:00 AM - 12:00 PM PDT

Presenter: Mojtaba Falahati, Senior Application Engineer at Ansys Zemax

Abstract:

Join Mojtaba Falahati, Senior Application Engineer, as he explores the optical-optomechanical design cycle for lens-grating-lens spectrometers using commercially available optical elements and describes how Zemax tools enable a joint workflow to turn optical designs into reality.

Optical spectrometers are instruments to measure the intensity of light as a function of wavelength. OpticStudio simulates the spectrometer setup, improves, and optimizes the optical design, and converts the optimized model to a CAD friendly format. Then, mechanical packaging using off-the-shelf components can be efficiently implemented in OpticsBuilder while accessing the live optics.

Interoperability between OpticStudio and OpticsBuilder streamlines the design process by:

  • Effective communication between optical and mechanical designers as they navigate the design changes.
  • Real-time visualization of impact on optical performance while designing optomechanics.
  • Detecting costly errors early in the design process.
  • Hassle-free export to OpticStudio for advanced analysis.

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

Yang

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: 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.

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.
