Gamma Scientific实时波长测量仪Wavemon

• 
  
  

• 
  

• Sub-nanometre resolution   and accuracy

• Five adjustable      transimpedance gain ranges and 24-bit ADC

• Data output via USB      (Windows/OSX/Linux support)

• ASCII command set for      simple control

The Wavemon system represents a significant advancement in real-time wavelength measurements. Using a multi-channel photodiode system, the unit provides amplitude feedback without the use of an expensive array spectrometer or sensitive optical alignment.

Applications

• Monochromator wavelength      monitoring

• Real-time production      testing for wavelength and amplitude

• 940nm VCSEL testing for      facial recognition

• LED device or wafer level      test and characterisation

• Production line or      laboratory use

Three photodiodes, each with an independent transimpedance amplifier circuit and 5 gain ranges for each channel, along with proprietary optical filtering techniques allows for wavelength accuracy of +/-0.25 nm and repeatability of +/-0.01 nm. Rock-solid stability and a reduced noise floor is achieved via a temperature stabilised feedback loop incorporating PID feedback.
