Embodiment Construction
[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0038] Such as figure 1As shown, the VIS / LWIR wide-band confocal optical imaging system includes a wide-spectrum focusing window 1, a color separation film 2, a long-wave infrared mirror group L1 and a visible light mirror group L2. Among them, the wide-spectrum focusing window 1 is placed perpendicular to the horizontal optical axis, the dichroic filter 2 is 45° to the horizontal optical axis, the visible light mirror group L2 is placed horizontally, and the incident light direction of the long-wave infrared mirror group is perpendicular to the horizontal optical axis. The above devices form two optical subsystems: infrared subsystem G1 and visible light subsystem G2. Infrared subsystem G1 is composed of wide-spectrum focusing window 1, color separation film 2, and long-wave infrared mirror group L1. Visible light subsystem G2 is co...
