Longer wavelengths of UV light, specifically within the UVA spectrum, penetrate deeper into photopolymers than shorter wavelengths such as UVC. This phenomenon is explained by Beer's law, which indicates that absorbance is greater at shorter wavelengths, leading to reduced penetration depth. The discussion emphasizes the importance of understanding this relationship for effective photopolymer applications.
PREREQUISITESResearchers, materials scientists, and engineers involved in photopolymer development and applications, particularly in fields such as 3D printing and UV curing technologies.
sdhpg said:For a photopolymer, the heuristic goes that longer wavelengths of UV light penetrate deeper than shorter wavelengths of UV light. For example, the UVA spectrum penetrates more deeply into the photopolymer than the UVC spectrum. What is the best way for this to be explained?
