An optical multi-layered thin film consists of the combination of various materials
and thicknesses to meet the capacity required for an optical filter.
Filters often needto separate the wavelength of special parts.
In particular, this is increasingly important for laser mirrors or spectroscopes.
Although the application scope of filters is broad, the scope will include one of the following coating types.
Although an optical system consists of a single factor or complex factor,
it is most important to control the transmission of energy that passes through the system.
Energy control means to maximize the amount of energy that passes through the system,
while minimizing the amount of energy that generally disperses or misses the target.
Non-reflection coating is the method that is the most ideal for this.
Non-reflection coating can be considered as an impedance transformer that delicately harmonizes theimpedance
between the media neighboring the coated surface.
Precise impedance adjustment in a single wavelength or in the very narrow band wavelength is relatively simple.
Also, 1 layer or 2 layer coating layers are enough for this method.
However, as wavelength band range increases, the number of coating layers increases
and it becomes gradually more difficult to maintain impedance perfectly with regard to the entire bands.
