UVA: Constructor of ultraviolet-A waveband

Description

Wavelength-range definitions for ultraviolet-A (UV-A) radiation, by default according to ISO or as commonly used in different application areas.

Usage

UVA(std = "ISO")
UVA1(std = "CIE")
UVA2(std = "CIE")
UVAsw(std = "plants")
UVAlw(std = "plants")
UVAsw(std = "plants")

Value

A waveband object defining a wavelength range.

Arguments

std

a character string "CIE", "ISO", "none", "medical" or "plants".

Details

Implemented definitions. UV-A according to CIE and ISO standards: 315-400 nm. UV-A according to common non-standard practice: 320-400 nm. UV-A2 according to CIE report 134/1: 315-340 nm. UV-A1 according to CIE report 134/1: 340-400 nm. UV-Asw according to non-standard use possibly suitable for plants: 315-350 nm. UV-Alw according to non-standard use possibly suitable for plants: 350-400 nm.
