M315X (X4, X6)
Two-piece medium temperature blackbody calibration source with a large surface area.
Ambient + 5 ... 400 °C (+ 9 ... 752 °F)
- High emissivity and uniformity
- Excellent general purpose calibration
- Large aperture sizes
- High accuracy, high resolution
- Manufactured and tested to meet rigid quality control standards
- RS232 (standard) or RS485 (option) serial communication output
Designed to satisfy the exacting parameters of Infrared focal plane array Detectors, Thermal Imaging, and FLIR systems testing in projection scene and field application, the M315X Series blackbody calibration sources combine high emissivity and unchallenged stability and uniformity. Available aperture sizes include 101 x 101 mm (4” x 4”) or 152 x 152 mm (6” x 6”) with a temperature ranges of ambient +5 to 400 °C (+9 to 752 °F).
The M315X Series Blackbody Sources are resistively heated by precision heating elements to provide uniform temperature distributions. The two-piece system is comprised of controller module and a separate enclosure for the emitter source.
Emitter source temperature control is carried out by a precision digital PID controller. RS232 is standard and RS485 is available as an option. Two connecting cables allow 3.6 m (12’) of separation between the blackbody source and the controller.
