What filter should I choose for a focusing lens in order to eliminate the infrared heat of sunlight, and at the same time have maximum light transmission?

What filter should I choose for a focusing lens in order to eliminate the infrared heat of sunlight, and at the same time have maximum light transmission? I'm trying to find this filter to put on a focusing lens to collect sunlight, but at the same time the heat did not come out.
Can you tell me what kind of filter this is?
