ZephIR 1.7 Deep-Cooled SWIR Camera

The ZephIR 1.7 is a high-end scientific InGaAs camera for low-noise SWIR imaging. Its 640 × 512 detector, 15 µm pixels, four-stage thermoelectric cooler and forced-air heat removal provide a maintenance-free cooling architecture capable of maintaining the sensor at -80 °C at 20 °C ambient.

Deep Cooling for Sensitive SWIR Measurements

The ZephIR 1.7 combines an InGaAs focal plane array with state-of-the-art control electronics and a four-stage thermoelectric cooler. The detector can be maintained at -80 °C at a 20 °C ambient temperature, substantially reducing dark current for demanding low-signal and long-integration measurements.

The TEC uses forced-air cooling, avoiding the water circulation or liquid-nitrogen handling required by many traditional deeply cooled scientific cameras.

  • Four-stage thermoelectric cooling
  • Forced-air heat removal
  • Low dark current
  • Low readout noise
  • High detector operability
  • External Trigger IN / OUT
  • PHySpec™ control software
  • C++ and Python SDK

Why Choose ZephIR 1.7?

ZephIR 1.7 is intended for scientific imaging where sensitivity, detector cooling, low noise and acquisition flexibility matter more than compact machine-vision form factor. The maintenance-free TEC + air system is especially attractive for laboratories that need deep cooling without plumbing or cryogens.

ZephIR 1.7x and ZephIR 1.7s Models

Two detector configurations cover either a broader visible-to-SWIR response or the standard InGaAs SWIR band. Both use a 640 × 512 InGaAs FPA with 15 µm pixels, -80 °C TEC cooling, USB 3.0 and Camera Link interfaces, 12 V DC power and external trigger I/O.
