Burleigh WA-1100 Optical Wavelength Meter uses Michelson interferometer-based WAVEMETER technology to ermine the absolute wavelength of an optical signal under test by comparing its interference fringe pattern with that of a built-in HeNe laser wavelength standard. 

Wavelength Range: 700 - 1650 nm (181 - 428 THz). 

Wavelength Absolute accuracy: ± 1.5 pm. Wavelength Display resolution: 0.001 nm. 

Power Absolute accuracy: ± 0.5 dB (at ± 30 nm from 1310 and 1550 nm). 

Power Resolution: 0.01 dB. Power Linearity: ± 0.3 dB. Power Display resolution: 0.01 dB.

 Optical Input Signal Sensitivity: -30 dBm (0.1 圀), 1200 - 1600 nm; -20 dBm (1.0 圀), 700 - 1650 nm. 

Maximum input level (sum of all lines): + 10 dBm (10 mW). 

Measurement Cycle Time: 0.1 s (10 measurements/s). 

Instrument interface: GPIB (IEEE-488.2), RS-232, LabVIEW, LabWindows
