Using microscope slides as beam splitter for Fourier transform spectrometers

A Fourier transform spectrometer using a regular microscope glass slide was built and was used to measure the spectrum of a tungsten light bulb source in the visible and near infrared spectral range successfully with satisfying outcomes. The obtained result was analyzed and compared with those obtained with a regular cube beam splitter. This experiment demonstrated that inexpensive microscope glass slides can be used as beam splitters for low￾cost Fourier transform spectrometers.
