In the world of lasers, "532" refers to the specific wavelength (532 nanometers) of green light produced by . This is perhaps the most common scientific reference for the number.
On the wrong assignment of the XPS O1s signal at 531–532 eV to oxygen vacancies (2021) In the world of lasers, "532" refers to
213 nm and 532 nm solid state laser treatment of biogenetical fibrous materials Vopper, 532 U
This paper is highly influential in the materials science community because it corrects a widespread misconception regarding the interpretation of oxygen signals in metal oxides. 4. Public Policy & Government NSF Solicitation 24-532: NSF Innovation Corps Hubs Program "532" often points to
