PhotriX with Fiber Optics connecting to Sapphire Lightpipe

Our most accurate pyrometer configured with a flexible fiber optic cable connecting the instrumentation to a remote, sapphire lightpipe. This configuration is ideal for induction heating processes requiring high accuracy and restricted optical access (e.g., vacuum process or narrow field of view).

Available in 4 different near infrared spectral responses (880 nm, 900 nm, 1550 nm and 700-1650 nm) with temperatures measured between 60 °C and 2600 °C.

Details

Our most accurate pyrometer, the PhotriX Series has the industry’s best signal-to-noise ratio allowing lower temperatures to be measured with unmatched precision for control of high-value processes and research applications. This configuration of our PhotriX series uses a flexible fiber optic cable to connect to a sapphire lightpipe that collects the infrared radiation from the target. This configuration is ideal applications using induction heating or when there is not optical access for a traditional lens solution to have sufficient viewing access to the target.

The Photrix with fiber optics connecting to lightpipe is offered in 4 spectral response (wavelength) versions and has the following features:

  • Low Temperature Capability (see chart below for details)
    • 60 to 900 °C or 100 to 1400 °C with 700-1650 nm spectral response
    • 100 to 2600 °C with 1550 nm spectral response
    • 240 to 2600 °C with 900 nm spectral response
    • 250 to 2600 °C with 880 nm spectral response 
  • Fast Response (1ms)
  • Accuracy of +/- 1.5 °C or 0.15% of reading
  • Precision of 0.01 °C (see TN-828)

Available options include analog output (user selectable 4-20 mA or 0-10V) and multi-channel interface modules allowing up to eight (8) sensors to be integrated into a single digital signal with parallel analog outputs. Standard system includes all necessary electrical cables, power supply, PC interface software and documentation/calibration.

Typical Applications

  • Induction heated susceptor temperature control
  • Solar Thin-film PV substrate measurement during deposition 
  • CZ Crystal Growth
