WebJul 18, 2024 · We use the grating constant to be b = 1600 nm. The calculation will look like this: λ = b sinα. λ = 1.6 ⋅ 10 − 6 ⋅ 0.09 0.09 2 + 0.25 2 m ≐ 542 n m. The wavelength of the laser is λ = 532 nm. The result differs by 10 nm, i.e. by less than 2 %. Technical Notes When you work with a laser pointer you must follow the safety rules. WebApr 11, 2024 · To study the appropriate value of gold (Au) film thickness for the optimization of the grating device, the transmission spectra ( $$\uplambda ,\mathrm{ a}$$ ) have been calculated for different Au film thicknesses while shedding light into the device at normal incidence keeping periodicity and slit width constant. The proposed 1D sinusoidal ...
