Newport MKS Optical Power Sensor, High Dynamic Range, 320-1060 nm, Free Space 2101

The 2101 High Dynamic Range Power Meter is temperature stabilized resulting in highly accurate and stable 320 to 1060 nm measurements. Unlike other power meters that slow considerably when switching sensitivity ranges, it incorporates a patent-pending logarithmic conversion circuit that achieves essentially seamless range switching, resulting in a useful dynamic range of >65 dB even at full speeds. This is about 20 dB better than conventional power meters. We've even provided three user-controllable speed settings so you can further extend the dynamic range if you don't need the speed. The convenient bolt-together modular design and daisy-chained power connections makes it easy to connect multiple units for multi-channel rack-mounted or bench-top systems. An external power supply, which must be purchased separately, is required – we recommend our 0901
