Optical Wavelength Meter
TQ8325 is a digital optical wavelength meter capable of high-accuracy and high-resolution measurements on the central wavelength of the light from laser diodes and LEDs for optical telecommunication.
Using He-Ne laser as the reference wavelength and Michelson interference method, the TQ8325 assures high accuracy measurement. The level meter is quite useful for alignment of the optical axis.
High Accuracy Measurement
The use of He-Ne laser as the reference wavelength attains a high measurement accuracy of 5 ppm. The He-Ne laser provides oscillation with highly stable wavelengths, assuring the high accuracy over a longn term without calibration.
High Resolution
Using the interference method, a maximum resolution of 0.001 nm can be achieved.
Wide Bandwidth
Short wavelength band (0.48 to 1.0 um) and long wavelength band (1.0 to 1.6 um) is easily switchable for measurement.
High Speed S
High speed sampling: 5 times/s
Frequency display possible
Auto Resolution
7 segment green LED display
