Infrared optic lens materials present a unique challenge to opto-mechanical design. In this video, we derive a Figure of Merit (FOM) that describes a commonly
The choice of housing materials for athermalizing optics can drastically change the length and weight of the optic. This video uses a previously derived Figure
In this video, two identical fastened loads are presented side-by-side. One is secured with a standard steel washer, while the other is secured with an
In this video, a change in temperature is applied equally to Aluminum, Ti-64, Invar-36 and ALLVAR Alloy 30. You’ll see the effect temperature changes have
Our webinar talks about how ALLVAR Alloys can provide solutions that can virtually eliminate thermal focus shift in sensitive optical systems. Dr. James A. Monroe
Creating a Tailored Thermal Expansion Part 1 – Using ALLVAR Negative Thermal Expansion Alloys to create a target CTE.
This video will teach you how to create a tailored thermal expansion by pairing positive CTE materials with Negative CTE ALLVAR Alloys. Using this method
In this video, we talk about multiple component elements in a complex assembly and how they can effectively be calculated to produce an overall zero
In this video, you can learn the best methodology to choose when – and for which materials – to use average CTE or instantaneous CTE
CTE can be calculated in different ways. Learn the differences between average and instantaneous CTE calculations and what it means for your design.
