DOP-201 Degree of Polarization Meter

600-1620 nm; No. of Channels 1, 2; PER Resolution 0.1 dB; PER Dynamic Range >40, >50 dB; Angular Resolution 0.06 dB; Input Optical Power Range -30-10 dBm; Power Resolution 0.02, 0.2 dB; Measurement Speed 0.1-10 sLuna’s ERM-202 is a single or dual channel polarization extinction ratio (PER) meter. When used with a broadband source, it directly measures PER. Single and dual channel models are available. The single channel instrument can be upgraded to a dual-channel version at a later date.The dual channel version is specifically designed to simultaneously measure the PER and power ratio of a device with two polarization maintaining (PM) outputs, such as a Y-branch fiber gyro IOC, PM coupler (PMC), or polarization beam splitter (PBS), as well as evaluate the performance (output DOP) of depolarizers.By combining low-noise circuitry with a high-resolution stepper, the ERM series achieves a PER dynamic range of 50 dB and an angular resolution of 0.06°, outperforming all competitors in its class. These instruments feature OLED displays with a high contrast bright readout that allows the data to be observed from several feet away. The instruments can be operated from the front panel or via remote control.The operator can choose from four measurement speeds ranging from 0.1 to 1 s/cycle to optimize speed or accuracy and can observe multiple parameters on the front panel screen including PER, axis angle, power ratios, and optical power. The measurement data can be stored and recalled for comparison purposes from the front panel as well. Full digital or remote control is included for unattended or system applications.Key Features:One or Two Measurement ChannelsFree-space InputFront Panel or Remote ControlSimultaneous Polarization Extinction Ratio (PER) and Power Ratio TestingPER Resolution: 0.1 dBPER Dynamic Range: >40, >50 dB High Angular Resolution: 0.06 dBOperating Wavelength Range: 1260 to 1620 nm, 960 to 1160 nm, 600 to 850 nmInput Optical Power Range -30 to 10 dBmPower Resolution: 0.02, 0.2 dBMeasurement Speed: 0.1 to 10 sBright OLED DisplayStore and Recall FunctionsDimensions: 356 x 216 x 89 mmApplications: Verification of PM Connectorization and Splices; Testing PM Fiber Coils; Simultaneous Measurement of PER and Power Ratio; Testing Y-branch Fiber Gyro IOCs; Testing PM Couplers (PMC) or Polarization Beam Splitters (PBS); Evaluating the Performance of Depolarizers; Laser Diode PM Fiber Pigtailing; PM Fiber Patchcord Production; PM Fiber Fusion Splicing QA; PM Fiber Coil and Fiber Gyro QA

632, 633 nm; Typ. Linewidth 1.0 MHz; Max. Output Power 10 mW CW; Threshold Current ≤120 mA; Slope Efficiency 0.4 W/A; Side Mode Suppression Ratio ≥30 dBToptica eagleyard’s DBR series of distributed Bragg grating (DBR) laser diodes contains a multi-section laser with gain, phase and distributed feedback (DFB) sections. DBR series laser diodes feature a built-in wavelength-selective grating stabilizing the wavelengthThe DBR series’ resonator comprises a periodic structure. Thus, the devices operate on a single resonator mode emitting quasi-monochromatic radiation with a very small line width and low phase noise. The lasers can have very low-intensity noise because of the lack of mode partition noise. Due to the Gaussian mode the output is diffraction-limited..Special variants are available, especially suitable for spectroscopy with mode‐hop free operation and small linewidth guaranteed at the specified target wavelength for spectroscopic applications – these laser diodes are reaching the target wavelength by temperature tuning and allow wavelength tuning around this target wavelength.Key Features:Center Wavelength: 632 nm, 633 nmNarrow Linewidth: Typ. 1.0 MHzThreshold Current: ≤120 mAHigh Side Mode Suppression Ratio: ≥ 30 dBMax.
