WebPrice : $ 1,225.00 An optical chopper is a mechanical device which physically chops a light beam into discrete light pulses. It is widely used in various optical experiments. It modulates different light sources with given frequency for their subsequent analysis. The chopping discs come in a variety of slot apertures and can be replaced with ease. WebJun 22, 2024 · The MC2000B Optical Chopper is a precision instrument that utilizes advanced features to modulate light from a continuous beam. The controller uses a phase-locked loop (PLL) motor speed control design to precisely maintain the chopping speed and phase relative to a reference signal. incoterm c\\u0026i
