The specifications given below is from the operating manual which comes with this item: 1. The TQ8325 is a Michelson interferometer with a HeNe laser as a reference frequency. 2. Measurement wavelength range: 0.6 μm~1.6 μm (in two different short and long wavelength bands). 3. Measurement frequency range: 187 THz ~ 500 THz (in two different short and long wavelength bands). 4. Measurement input level: -23 dBm to +3.0 dBm (0.6 μm~1.0 μm band) -20 dBm to +3.0 dBm (0.6 μm~1.4 μm band) -15 dBm to +3.0 dBm (1.4 μm~1.6 μm band) 5. Display: 7 digits (decimal), green LED 6. Display resolution: 1 nm, 0.1 nm, 0.01 nm, 0.001 nm or 100 GHz, 10 GHz, 1 GHz, 100 MHz 7. Measurement wavelength accuracy: ± wavelength spectral width (nm) x 5/100 ±5ppm ± 1 count 8. Measurement frequency accuracy: ± frequency spectral width (GHz) x 5/100 ± 5ppm ± 1 count We have also done some cross comparisons of the frequency and wavelength measurements of this meter with our other TQ8325 meters. Readings for various stabilized light sources up to 1550 nm were in the range of wavelength and frequency accuracy of 5ppm indicated in the manual. 1- Advantest TQ8325 wavelength meter (please look at our rules and privacy policy) |
