Definition
Meaning and Definition
A lens that causes parallel rays of light to spread out (diverge) after passing through it; also called a concave lens.
In optics, any lens thinner at its center than at its edges, with a negative focal length, used to correct nearsightedness or to create virtual images. Metaphorically, can describe something that causes views, opinions, or paths to spread apart.
Dialectal Variation

Differences
No significant lexical differences. The terminology is standardised internationally in physics and optics. Spelling of related terms follows regional norms (e.g., centre/center).
Connotations
Identical technical connotations.
Frequency
Equally low frequency in both dialects, confined to technical contexts.

Common Mistakes When Using “diverging lens”
- Misidentifying it as a magnifying lens (which is converging).
- Incorrect plural: 'diverging lenses' (correct).
- Misspelling as 'diverjing lens'.
- Using it as a verb phrase (e.g., 'The lens is diverging the light' is grammatical but 'a diverging lens' is a compound noun).
FAQ
Frequently Asked Questions
Yes, in most common contexts. 'Diverging lens' describes its function (makes light diverge), while 'concave lens' describes its shape (curved inwards). For simple lenses, they are synonymous.
No, a single diverging lens can only produce virtual, upright, and diminished images. Real images require converging light rays.
Primarily in the corrective lenses of eyeglasses or contact lenses for people with myopia (nearsightedness). They are also used as part of more complex optical systems in cameras, telescopes, and peephole door viewers.
By convention in optics, the focal length of a diverging lens is negative. This is a key mathematical distinction from a converging (positive) lens.
A lens that causes parallel rays of light to spread out (diverge) after passing through it.
Diverging lens is usually technical / academic / scientific in register.
Diverging lens: in British English it is pronounced /daɪˈvɜː.dʒɪŋ lenz/, and in American English it is pronounced /daɪˈvɝː.dʒɪŋ lɛnz/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think: 'Di-verging' sounds like 'die-verging' – imagine the light rays 'dying' (spreading out and fading) as they pass through the lens. Or, the lens is thin in the centre like a cave (concave), making rays cave outwards.
Conceptual Metaphor
KNOWLEDGE/IDEAS ARE LIGHT; CLARITY IS FOCUS. Therefore, a 'diverging lens' could metaphorically represent a principle or argument that scatters or diversifies viewpoints rather than unifying them.
