Exchangeable lens for PI400i /450i and PI450i G7 (ACPI4XXIxxx)

Made for the PI400i /450i Series with Superior Optical Performance

The PI400i /450i and PI450i G7 are infrared cameras for researchers and process engineers with a wide temperature range from -20°C to 900°C (extendable to 1500°C). One of its key features of the PI series is the range of exchangeable lens options available, which allows for precise customization based on specific measurement requirements. The PI series offers excellent optics quality due to the small Minimum Field of View (MFOV), ensuring high precision and clarity in temperature measurements. The IR camera can be equipped with lenses, ranging from 18° to 80° field of view. Each optic is calibrated with the IR camera up to 1500 °C.

  • Lens options ranging from 18° to 80° field of view
  • Superior optical design allows small MFOV and High Distance-to-Spot Ratios
  • Calibration included
