Light from a light source enters the lens, and heat generated from the light source is also transmitted. At this age, the lens closer to the light source receives more heat. To use other materials for the mount, the heat causes the mount to expand and shift the focal point of the lens, resulting in image distortion. On the other hand, if the low-heat Peng Zhang material of the present invention is thinned as a mount, even if heat is applied from a light source, the focus shift of the lens can be suppressed or prevented, so that a more accurate image can be obtained. it can.
