The phrase "a main wavelength" is correct and usable in written English.
It can be used in contexts related to physics, optics, or telecommunications when discussing the primary wavelength of a signal or light source.
Example: "In this experiment, we will focus on a main wavelength of 500 nanometers to analyze the light spectrum."
Alternatives: "a primary wavelength" or "a dominant wavelength".
The authors solved the arc light overexposure issue by using a He-Ne laser source (main wavelength 632.8 nm) with a bandpass filter and an Ω-type optical setup, allowing them to analyze the interface between the shield gas and surrounding air for different operating currents and shield gas flow rates.
They investigated a 30 A cutting torch on a rotating anode by using a z-type schlieren system with a vertical knife edge and a 20 mW continuous laser source (main wavelength 632.8 nm) with a bandwidth filter to block the arc light.
The same authors [109] improved their technique by using an additional laser source (main wavelength 514 nm), another bandwidth filter and a beam-splitter to allow the use of both laser sources.
The synthesis of PEDOT-PtNP composite was carried out by putting a glass bottle, containing 0.01 M of EDOT monomer and 0.001 M of H2PtCl6 aqueous solution, in a photochemical reactor (Panchum Scientific Corp., Taiwan) followed by irradiation with UV light (power density, 0.14 W cm−2; main wavelength, 365 nm) for a specific period of time under forced air convection and mild agitation.
That is the main wavelength of the infra-red radiation emitted by fierce forest fires.In this section Access all areas Seeds of change Making the connection Beetle drive ReprintsDr Schmitz and Dr Müller have constructed a prototype artificial version of this sensor using tiny plates of polyethylene instead of cuticula.
Fig. 1 The main wavelength and the particular wavelength for amylose were 554 and 490 nm and the main wavelength and the particular wavelength for amylopectin were 542 and 713 nm.
Although the main wavelength was 1.01 εm at the earlier stage of the present project, it was changed to 0.90 εm.
The main purpose of this study is to investigate the enhancement of solar thermal energy harvest by silicon nanowire structures where the spectral optical properties including light absorption and scattering vary in the main wavelength range of solar irradiation.
Prior to the irradiation, the suspensions were magnetically stirred in the dark for 30 min to realize adsorption equilibrium; afterward, the photoreaction vessel was exposed to UV irradiation (500-W high-pressure Hg lamp with the main wavelength at 365 nm) under ambient conditions to start the photocatalytic reaction.
