Recent advancements in photonics technologies have broadened their applications into many different areas. An increasingly larger number of complex and diverse forms of light sources are designed into various systems and experimental setups. These complex light sources drive the need for more sensitive and versatile power measurement capabilities with high accuracy. Newport’s Model 1936-R or 2936-R allows reasonable temporal signal measurements, eliminating the need for multiple instruments in some cases (Figure 1). Available as a single or a dual channel model, these optical power meters has several sophisticated features that allow the user to achieve various measurements, including frequency measurements of pulses up to 200 kHz, depending on the signal range and the pulse shape.
