Frequently Asked Questions

The Polarization Extinction Ratio Meter is used to measure the output extinction ratio of light from a fiber.

With the optional neutral density filters, power levels up to 2 Watts can be measured.

The wavelength range is very wide, ranging from 450 to 900 nm for visible wavelengths, and 850 to 1650 nm or 1800 to 2400 nm for IR wavelengths.

The Extinction Ratio Meter has an accuracy of ±0.15 dB for extinction ratios up to 30 dB, and an angle accuracy of ±0.5°.

The meter operates in real time mode, giving the extinction ratio and alignment, and in logging mode, giving the worst case extinction ratio over a given time span.
