Oxforddictionaries.com:

incident:

2. (Especially of light or other radiation) falling on or striking something

usage examples:

– when an ion beam is incident on a surface
– There is a resonant interaction of the incident light with the surface plasmons on both surfaces of the metal film.
– The intensity of all monochromatic incident light was kept close using neutral density filters.
– Further, nitrogen-based defensive compounds tend to increase under both high nutrient availability and reduced incident radiation.
– This orientation minimizes the polymer's exposure to incident light and hence lowers observed fluorescence.

Apochromatisch gecorrigeerde OPVALLEND LICHT objectieven met hoge vergrotingen =
High-power, apochromatically corrected objectives for REFLECTED LIGHT (micro-shop.zeiss.com via Linguee)

De kleuren zijn meestal erg bont en helemaal niet mooi om te zien bij OPVALLEND LICHT, maar van achteren belicht worden de kleuren zacht, verstrooid en erg mooi. =
The colours are often garish and not at all agreeable when viewed with REFLECTED LIGHT, but with the transmitted light the colours become soft, diffused, and extremely pleasing. (luikerwaal.com via Linguee)

[...] van de camera ontstoken (dus zonder dat de film wordt belicht) en meet met een flits-belichtingsmeter met een lichtverstrooiingskapje in de richting van de camera gericht de hoeveelheid OPVALLEND LICHT. =
If you have arranged everything to your satisfaction one ignites the studio flashlight without activating the camera shutter and measures the INCIDENT ILLUMINATION with a flashmeter aimed at the camera. (focusonpictures.com via Linguee)
