quasi-optical system

The kit includes:
• Generator on avalanche-transit diode - the wavelength of 2 mm (140 GHz)
• pyroelectric detector with mouthpiece
• Electronic power supply with synchronous detection and USB 1.1 interface
• The polarization grating
• four-stage attenuator (1, 3, 10, 30%)
• Fabry-Perot interferometer, the resolution of 120 MHz
• Membrane grating device for measuring the angle of the intensity distribution
• The lens, absorbing screens, plates of variable thickness.
The system can be used for reflection and transmission measurements, determine parameters dielectric substances sample thickness, latent defects, as well as for educational purposes.
