INSTRUMENTS AND METERS

With solutions ranging from versatile vector analyzers to high-performance parametric testers, Luna’s optical component testing solutions can help you verify new designs or optimize products.

Versatile vector analyzers
High-performance parametric testers
Unmatched speed, precision and accuracy
Accelerates and improves design
Optimizes production

A suite of benchtop measurement instruments from Luna (a product line originally developed under the General Photonics brand) for characterizing the polarization properties of light and fiber-optic components. Four complementary meters cover the most common tasks in the photonics laboratory and on the production line: measurement of the degree of polarization (DOP), polarization extinction ratio (PER), polarization-dependent loss (PDL) and full real-time analysis of the state of polarization (SOP). The DOP-201 and PDL-201 instruments use a patented maximum–minimum search method, providing high accuracy for both low and high DOP/PDL values — calibration-free across the wide 1260–1620 nm range.

Applications

Manufacturing and quality control of depolarizers and ASE and SLED sources
PM fiber pigtailing: laser diodes, modulators, integrated optical circuits (IOC)
PDL/IL characterization of passive DWDM and sensing components
Monitoring of the state and degree of polarization in optical paths (SOP/DOP)
Quality control of PM fiber splicing and PM patch cord production
Characterization of fiber-optic gyroscope coils

Key parameters

Parameter	Value
Model	Function and key parameters
DOP-201	Degree-of-polarization meter; 1260–1620 nm, DOP 0–100 %, accuracy ±0.5 % (±0.2 % for the average of 10 measurements), input power from −40 to +6 dBm, 30 ms measurement

PDL-201 PolaChex	PDL/IL/power multimeter; 1260–1620 nm calibration-free, PDL range 0–45 dB, accuracy ±(0.01 dB + 5 % of value), 30 ms measurement; USB, Ethernet, GPIB, RS-232
POD-201 PolaDetect	Polarimeter with FPGA; sampling up to 4 MS/s, ranges 1480–1620 nm or 1280–1340 nm, SOP/DOP measurement (Stokes parameters), PER 0–40 dB, PolaView software

Common platform for measurement automation

All instruments in the series are designed for operation both at the laboratory bench and in automated production stations: clear OLED displays, analog outputs proportional to the measured quantity, and communication interfaces for remote control. The short single-measurement time (30 ms in the DOP-201 and PDL-201) enables 100 % inspection of products in volume production, while the POD-201 polarimeter with sampling up to 4 MS/s also captures fast, transient polarization changes. Data sheets for all four instruments are available in the downloads section.
