Edmund Optics White Paper: An introduction to passive athermalization

For imaging applications that are prone to temperature fluctuations, it is important to develop an athermal optical system: an optical system that is insensitive to an environment’s thermal change and the resulting system defocus.

This White Paper from Edmund Optics offers an introduction to passive athermalization. It provides crucial information about how temperature changes could affect the performance of your imaging system, and advises on how to select materials for your optical assembly in order to mitigate these potentially adverse thermal effects.

Who should download this White Paper?

This White Paper is a useful reference for engineers at OEMs or academic institutions who are working on the types of vision applications that can be prone to temperature fluctuations.

Why download this White Paper?

This White Paper explores:

  • Why developing an athermal design for an imaging system is critical in certain applications
  • How to gain the knowledge to be able to design a system in these cases and why it is important
  • How Edmund Optics can help, thanks to its expertise and ability to  design for and guide you in solving your imaging system challenges

It also provides advice on thermal defocus and achromatic & athermal doublet equations, and offers an alternative graphical method for choosing achrotherm glass and housing materials.

Downloading this White Paper will offer engineers a useful resource that concisely describes how to select materials for an athermal optical assembly and sets out the 10 most important equations for its design.
