Ask an Expert: How Does F# Affect Lens Design?

Part 2 of our discussion on F# continues with Chris Johnston discussing the relationship between F# and lens design for Infrared cameras. We showcase two sets of infrared cameras with similar features and see how different wavelengths and F#'s change aspects of their weight, application, and capabilities.

Look at the size of that lense...I can't imagine how much it cost??

[@SierraOlympia]

It's a common misconception that the size of the lens directly correlates with the cost of a camera. It's important to note that mid-wave systems require additional cooling, contributing to their higher cost compared to long-wave systems, which don't necessitate the same cooling setup. So, while these cameras are indeed expensive, the size of the lens alone doesn't determine their price.

@@SierraOlympia Thanks for answer..I though that it's more expensive because of a lot of germanium glass in big camera
