Emisný

Emisní is a Czech adjective relating to emission or issuing, derived from the noun emise (emission, issue). The term is used across several fields to describe substances released, signals sent, or securities issued, depending on context.

In environmental and regulatory contexts, emisní describes the release of substances into the environment. Common collocations include emisní norma (emission standard), emisní limit (emission limit), and emisní povolenka or emisní povolenky (emission allowances) used in cap-and-trade systems. Emisní faktory are factors used to estimate pollutant emissions from activity data, such as fuel consumption or industrial processes. The term appears in legislation, impact assessments, and air- and water-quality monitoring.

In physics, chemistry, and spectroscopy, emisní refers to the release of energy or radiation by a source. Emisní spektrum (emission spectrum) denotes the spectrum of light or other radiation emitted by a material, while emisní čára (emission line) describes discrete wavelengths produced by atomic transitions. These concepts contrast with absorpní (absorption) phenomena and are fundamental in analysis of materials and astrophysical observations.

In electronics and communications, emisní can describe electromagnetic emissions or signals produced by devices or systems. The term is used when discussing compliance with electromagnetic compatibility standards and in the design of circuitry to control unwanted emissions.

In finance, emisní relates to the issuance of securities. Emisní plán and emisní cena (issue price) are terms that appear in discussions of bond or stock offerings, regulatory filings, and capital-raising activities.
