Okay, the user wants me to translate "scotopic illumination" into Thai. Let me check if the term is already in Thai. Since it's an English technical term, I need to translate it properly.
First, "scotopic" relates to vision in low light, so in Thai, that's "การมองเห็นในที่มืด" or "สโคโทปิก". "Illumination" is "การส่องสว่าง". Combining them, it might be "การส่องสว่างสโคโทปิก" or "การส่องสว่างในที่มืด". I should confirm the standard translation for technical terms. Maybe "สโคโทปิก" is the accepted term in Thai scientific contexts. So the translation would be "การส่องสว่างสโคโทปิก". Let me make sure there's no existing Thai term that's more commonly used. If not, the direct translation should be acceptable.
