Overview
The NLIR-D2250 series single wavelength infrared detector is used for narrowband (single wavelength) detection, and the narrowband center wavelength can be set between 2.2-5.0 μ m. The system bandwidth is DC-10GHz, and the noise equivalent power is as low as 10 Flywatts. It is plug and play and easy to use. According to the needs, a wavelength tunable system (variable center wavelength system) can also be selected.
Product Details
NLIR-D2250 seriesSingle wavelength infrared detectorUsed for narrowband (single wavelength) detection, it has the following characteristics:
1.Narrowband (single wavelength) detection, the center wavelength of the narrowband can be within2.2-5.0MmBetween settings;
2.Wavelength tuning (variable center wavelength system) optional
3.Noise equivalent power as low as 10 fW/Hz1/2
4.DC-10GHzbandwidth
5.Plug and Play
Product Introduction:
The main limiting factors for the performance of mid infrared detector systems include1）The detector itself has a huge inherent noise;2）The detector receives a large amount of noise radiation from the surrounding environment.NLIRThe detector is used through1）Narrowband detection technology;2）Efficient up conversion technology; The combination with low-noise silicon-based detectors effectively alleviates the limitations of the above two factors on the performance of the detection system.
In addition to excellent sensitivity, extremely fast response speed, and low noise characteristics,NLIRR&DD2250The detectors are pre installed with matching preamplifiers to amplify the output signal to a level suitable for direct measurement by the oscilloscope, eliminating the hassle of designing and manufacturing preamplifiers for users and achieving true plug and play functionality.

Note:
（1） The maximum optical bandwidth is related to the center wavelength: the longer the center wavelength, the wider the bandwidth（4.2MmThe bandwidth is200nm）；
（2） Broadband detection can be customized according to user requirements. The bandwidth of broadband detection usually reduces responsiveness;
（3） This refers to the maximum detection power across the entire electrical bandwidth;
（4） This parameter is wavelength3.5MmThe minimum optical bandwidth at;
（5） Built in for adjusting the light path532nmLow power guiding beam.
