What Software Can Design a High-Accuracy Collimator Lens?

Click For Summary

Discussion Overview

The discussion centers around the design of a high-accuracy collimator lens capable of collimating light from off-axis points with a divergence angle of less than 1 micron. Participants explore software options for lens design and share insights on potential approaches to solving the problem, including manual calculations and ray tracing methods.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • One participant requests recommendations for software to design a high-accuracy collimator lens.
  • Another participant suggests Zemax as a suitable software, noting its high quality.
  • A participant inquires about the availability of Zemax online and expresses concern about its cost and hardware key requirement.
  • It is mentioned that Zemax is expensive, but cheaper than Code V, with a link provided for further information.
  • A free educational version of OSLO is suggested as an alternative, although it has limitations on the number of components.
  • One participant expresses urgency in finding a solution and asks for guidance on how to proceed.
  • Another participant suggests either using the OSLO free version or performing manual calculations to solve the problem.
  • A participant proposes the Q-u method (ray tracing) as a potential approach for the design.
  • One participant questions the necessity of designing a custom lens and suggests using an existing lens, such as a camera lens or telescope, as a simpler alternative.
  • A participant clarifies the specific requirements for the lens design, detailing the need to collimate light from an optical fiber with a conical shape and a diameter of 600 microns, while addressing the issue of divergence.

Areas of Agreement / Disagreement

Participants express differing opinions on the best software for lens design, with some advocating for Zemax and others suggesting OSLO or existing lenses. The discussion remains unresolved regarding the most effective approach to the problem.

Contextual Notes

Participants mention limitations related to software costs and capabilities, as well as the complexity of designing a custom lens versus using existing solutions.

Hi

I want to make a high accuracy collimator lens, such that it collimates ( with divergence angle < 1 micron) a beam of light coming from the focal plane but from off axis points as well ( -delta to + delta, where delta is in microns).

Sugest some suitable softwares (along with the link) which can be used to design this lens, and give any idea which u may have.

Thanks for the help
 
Engineering news on Phys.org
Can i find zemax on the internet. If yes, pls give me the link! I found one on their website, but its asking for hardware key. So I guess its not a free software :(
thanks a lot in advance
 
Nope it's quite expensive software (http://www.zemax.com/index.php?option=com_content&task=section&id=8&Itemid=135 ) but very cheap compared to code-V (http://www.opticalres.com/cv/cvprodds_f.html)

The only free optical design software I know of is the educational version of OSLO (http://www.sinopt.com/ ) - I don't think you need to be education but it is limited to system with only very few components. The interface is a little old fashioned but the answers are just as good as zemax

can u suggest me a wayout. I need to do this as soon as possible!
 
Either OSLO free version, or just do the maths yourself
 
Can u please outline the strategy how should i go about solving this. (How can i attack the problem in i have to do it manually). Actually this is the first time i am doing something like this.
 
I think I may have to use Q-u method ( ray tracing). right?
 
What exactly are you trying to do ?
It may be easier to just use a finished lens, a camera lens or a telescope rather than trying to assemble your own.

Take a look at the edmunds (http://www.edmundoptics.com/) aswell, they also have very good technical support

I have to design a lens which collimates a beam of light coming from a optical fiber (it will come in conical shape) of diameter 600 microns. Now, obviously, the light will come from off axis points as well. So if the face of the fiber is kept at the focus of a normal lens, then after collimation, the beam will have diverge ( I hope u can imagine why). I want to take care of this divergence (should be less than 1 mrad).

Thanks
