Product Description
The ANDO AQ2734 is a high‑performance sensor unit for the AQ2140 optical multimeter series. It uses a cooled InGaAs photodiode with a wavelength coverage of 900 nm–1870 nm, suitable for broadband optical power and loss measurements and supports accurate detection in the 1650 nm band.
Key Features
-
High Accuracy: Measurement accuracy of ±2.5% under reference conditions
-
Wide Wavelength & Large Dynamic Range: Covers 400 nm–1870 nm with a dynamic range of ≥100 dB (sensor‑dependent)
-
Low Polarization Dependence: Polarization dependence ≤0.02 dBp‑p, minimizing polarization effects
-
1650 nm Band Support: Photodiode response is flat from 1300 nm to 1800 nm, enabling precise 1650 nm measurements
-
Stable Light Source: Internal isolator in the LD unit keeps output power stable within ±0.003 dB
-
Optical Power Attenuation: Power can be reduced in 0.1 dB steps up to 6 dB for fine adjustment
-
Connector Versatility: A wide variety of optical connectors are supported by swapping universal adapters (except AQ4214)
