Meaning and Usage

Optical path length refers to the product of the geometric length of a light path and the refractive index of the medium through which the light travels. It is used primarily in the fields of optics and photonics to describe how light behaves as it moves through different media. The term is frequently used in both written and spoken contexts, especially in scientific discussions. Its frequency of use is more common in academic and technical writings due to its specialized nature.

Example Sentences: 1. Understanding the optical path length is crucial for designing effective lenses in optical instruments. - С пониманием оптической длины пути крайне важно для проектирования эффективных линз в оптических инструментах.

1. The optical path length can vary significantly based on the refractive index of the materials involved.

2. Оптическая длина пути может значительно варьироваться в зависимости от показателя преломления задействованных материалов.

3. Researchers often measure the optical path length to improve the accuracy of their experiments.

4. Исследователи часто измеряют оптическую длину пути, чтобы повысить точность своих экспериментов.

Idiomatic Expressions

While the phrase "optical path length" is not commonly part of idiomatic expressions, it is often used in combination with terms related to optics and light propagation.

Example Sentences with Related Expressions: 1. When light travels, its optical path length can shorten with higher refractive materials. - Когда свет проходит, его оптическая длина пути может сокращаться с помощью более высоких преломляющих материалов.
