Optical spectrum switching device and turnable optical filters are key elements for optical networks, spectroscopy and optical sensing. In this work we proposed and analysis the prism type tilt incident optical systems for continuous tuning and optical spectral switching by using the non-micro-electro-mechanical systems. The interference filter air gap is fixed, and wavelength tuning is achieved through scanning the angle of incidence by pre-located rotating prism. The spectral transmittance calculations at different angle of incident show good qualitative agreement with the experimental results. We can get the peak wavelength shift is about 3.7㎚ at 633㎚ by the prism rotations about 1 degree.
