This unique new infrared detector design from the R&D lab at InfraTec was developed to allow scanning over a range of wavelengths by simply adjusting the control voltage. Instead of mounting filters to inspect specific areas of interest, the Fabry-Perot filter control can be used to monitor a broad spectral region continuously.

• Electrostatic drive
• >1µm tuning range
• resolving power λ/ Δλ up to 60
