1)Is it possible to concentrate infrared radiation from a blackbody with a lens?
2)Should a lens be at different temperature from a blackbody?

Do you think something similar to what I was thinking about could be practically created?With help of mirrors?Should thouse mirrors stay at different temperature from underground cavity?Ah, you don't seem to mean for imaging purposes, but for long-term energy transfer purposes.

A lens is able to concentrate radiation from a blackbody by refracting, or bending, the light rays that pass through it. This refraction causes the rays to converge at a single point, increasing the intensity of the radiation at that point.
A blackbody is an idealized object that absorbs all radiation that falls on it. In this context, a blackbody is used because it radiates energy at all wavelengths according to its temperature, making it an ideal source for studying the properties of radiation.
The shape of a lens can greatly affect its ability to concentrate radiation. Lenses with a larger curvature, such as convex lenses, are able to bend the light rays more and therefore concentrate the radiation to a greater degree. Additionally, the size and placement of the lens in relation to the blackbody can also affect its concentration abilities.
No, a lens is not able to concentrate all wavelengths of radiation equally. This is due to the phenomenon of chromatic aberration, where different wavelengths of light are refracted at slightly different angles. This results in a slight separation of the wavelengths and can affect the concentration of radiation.
There are many potential practical applications of concentrating radiation from a blackbody with a lens. One example is in solar energy collection, where lenses can be used to concentrate sunlight onto a smaller surface area, increasing the efficiency of energy conversion. Another application is in infrared imaging, where lenses can be used to focus thermal radiation emitted by objects to create detailed images for various purposes such as medical imaging or military surveillance.
