VariWave Variable Frequency Microwave Laboratory Oven VariWave Variable Frequency Microwave Laboratory Oven

Lambda’s patented VFM technology offers precise control and uniform distribution of microwave energy for a broad range of thermal applications. Unlike conventional industrial microwave ovens that use a fixed frequency magnetron, VFM products use a broadband microwave amplifier to enable optimum frequency selection and the ability to sweep around a center frequency to ensure good mode density and energy uniformity. Sweep rate control also ensures that VFM technology is compatible with metallic components or fixtures, without arcing, and with electronic circuitry or semiconductors without causing damage.
