2101 In Stock

The Newport 2101 is a High Dynamic Optical Power Meter designed for precision measurements in the wavelength range of 320 nm to 1060 nm. This temperature-stabilized power meter ensures reliable and accurate readings even under varying environmental conditions. The 2101 stands out with its logarithmic conversion circuit, enabling fast and seamless range switching. This results in an impressive dynamic range of greater than 65 dB, significantly surpassing other comparable power meters by 20 dB.

The 2101’s modular design and daisy-chained power connections simplify the process of connecting multiple units for multi-channel bench-top or rack-mounted systems. This feature allows for seamless integration into various setups and enhances the overall efficiency of optical power measurements. The power meter's logarithmic conversion circuitry enables it to provide an analog output that spans over 70 dB of optical input power, catering to the needs of swept-wavelength optical loss measurements. With fast rise and fall times, the 2101 facilitates high-speed measurements, achieving a minimum of 100 nm per second.

For ease of data collection, the 2101 offers a conversion gain of 50 mV/dB of optical power, allowing the full sensor range to be converted to a digital signal with exceptional 0.01-dB resolution. This eliminates the need for multiple-laser sweeps and user-controlled gain switching, ensuring faster data collection without compromising accuracy. The 2101's fast analog response makes it ideal for viewing high-range signals on an oscilloscope, making it a versatile tool for various laboratory applications. Moreover, its compatibility with multiple power meters enables convenient rack mounting and testing of multi-channel devices, further enhancing its usability.

To reduce noise in scenarios where response speed is not critical, the 2101 offers three filter settings. The fastest setting allows for a small signal rise time of 30 µs and an analog bandwidth exceeding 25 kHz. This capability facilitates measurements of narrow optical filters at 100 nm per second wavelength sweep speeds. It is important to note that the 2101 requires a warm-up time of approximately five minutes for active temperature stabilization of the photodiode and critical circuit components, ensuring full accuracy. Users should be attentive as there is no status light to indicate when the ambient temperature is outside the operating range.
