There are several materials used to create a thermal camera, including:

1. Thermal sensor: This is the core component of a thermal camera, and it is made of several materials such as amorphous silicon, vanadium oxide, and microbolometers.

2. Lenses: Thermal camera lenses are typically made of germanium or silicon. Germanium is commonly used because it has a high index of refraction and is transparent to long-wavelength infrared radiation.

3. Housing: The housing of a thermal camera is designed to protect the components from elements and extreme temperatures. It is typically made of materials such as aluminum, polycarbonate or ABS plastic.

4. Circuit board: The circuit board of a thermal camera is typically made of fiberglass or epoxy resin with copper traces.

5. Display: The display used in a thermal camera is generally an OLED or LCD screen.

6. Battery: The battery used in a thermal camera is typically a lithium-ion polymer battery.

7. Packaging: The packaging is usually made of cardboard or other recyclable material to reduce the environmental impact
