| 摘要 |
The invention relates to an optical system for testing IR or UV sensors, comprising input optics (1), output optics (2) having a reticule (5) disposed on the associated optical axis, a radiation source (4), which emits radiation intensity in the visual spectral region and in the infrared or ultraviolet spectral region, and a beam splitter (3) for simultaneously visualizing an object scene illuminated by the radiation source (4) with the reticule (5) through the output optics (2) into the eye (9) of an observer, wherein the input optics (1) comprise a lens, the imaging properties of which in the visual spectral region are equal to the imaging properties in the infrared or ultraviolet spectral region and the beam splitter (3) is a dichroic beam splitter. |
