Near infrared region (NIR) of the electromagnetic spectrum (EM) is defined as 700nm to
1400nm wavelength interval by International Commission on Illumination(CIE). This wavelength
interval is extensively used for target acquisition, night vision, wireless communication
etc. Therefore, filtering the desired portion of EM spectra becomes a need for that kind
of applications. Interference filters are multilayer optical devices which can be designed and
produced for the desired wavelength intervals. The production of near infrared interference
filters is a process of depositing thin material layers on the suitable substrates. In this thesis, a
multilayer NIR filter will be designed for a selected wavelength interval by the use of dierent
materials. Then, transmission quality, thermal stability, dependence of the transmission
values on the incoming beam angle, performance and durability of the filter will be studied.
