Hubble was originally designed to observe in the visible and ultraviolet parts of the spectrum, but a 1997 mission added an infrared observing capability.

哈勃望远镜的最初设计是只能观察光谱中的可见光和紫外线部分，后来在1997年增加了红外观测能力。

Photovoltaic cells are usually most responsive to photons in the visible and ultraviolet parts of the spectrum, but they can also respond to high-frequency infrared photons.

光伏电池通常对光谱中的可见光和紫外线波段的光子受激性最好，但高频红外光子也能激发电流。

For example, iron-gall ink, commonly used on ancient documents, is transparent to infra-red light and most visible in the ultraviolet region of the spectrum.
