OTF Studio workshop is an excellent opportunity to learn more about tits capabilities and gain hand-on experience.
Periodic multilayers with shifted ratios of high and low index layers in the half-wave pairs
Fig. 1. Schematic representation of a quasi-notch filter exhibiting high-reflection zone HR centered around a central wavelength $\lambda_0$. There are two possible structures S1 and S2.
Here you can estimate reflectance at central wavelength and width of HR zones of the quasi-notch filters of different structures (s-polarization case). Input the parameters required for calculations:
Fraction of quarter wave p (0.0-1.0): = Central wavelength (100 nm - 25000 nm) nm Number of layer pairs: m =
Refractive indices of layer materials: n1 = n2 = Substrate refractive index: ns = Angle of incidence (0-89 degrees): degrees
