(27.6.2) θ = 1.22 λ D = x d, onde d está a distância entre a amostra e a lente objetiva, e usamos a aproximação de pequeno ângulo (ou seja, assumimos que x é muito menor que d ), de modo que tan θ ≈ sin θ ≈ θ. Portanto, o ... WebApr 11, 2024 · For calculating the focused laser beam, we use the Rayleigh Formula (1) to calculate the Rayleigh length, which is determined by the beam waist radius and wavelength . (1) At present, the most commonly used laser wave lengths in the market are 1064 nm, 532 nm, and 355 nm. In our method, we focus on = 1 mm and = 532 nm.
