I want to inspect small electronic components with a Seek Thermal CompactPro and need the camera to focus much closer. The branded zinc selenide macro lenses seem very expensive. What type of lens is needed, and what specs matter if I want to buy a separate lens instead?

You need a ZnSe convex or planoconvex lens. Placing it in front of your existing lens will allow it to focus closer.
Search for "ZnSe lens" on your favorite shopping sites. Many are listed as condenser lenses for CO2 lasers for around $15-20.
Make sure the diameter is large enough to cover the front element of your existing lens. Thare aren't really any other relevant specs since you'd be using it as an auxiliary lens to modify the function of your existing lens.

For a thermal camera like the Seek CompactPro, you need a zinc selenide (ZnSe) auxiliary lens placed in front of the existing lens so it can focus closer. A convex or plano-convex ZnSe lens is the type mentioned by users.
The key practical spec is diameter: it should be large enough to cover the camera’s front lens element. Since it works as an add-on close-focus lens rather than a full replacement, there usually aren’t many other critical specs to match for basic macro use.
ZnSe lenses are commonly sold as condenser lenses for CO2 lasers, so searching for “ZnSe lens” may turn up suitable options. If you want a DIY example, look for videos about adding macro capability to a Seek thermal camera.
