Mikron PhotriX® Pyrometers

Short-wavelength Low-temperature Pyrometers

The Mikron PhotriX ® range of short-wavelength low-temperature pyrometers offers class-leading accuracy at unrivalled low-temperature capability.

The PhotriX ® range can be configured with four different spectral responses and the collection optics can be configured in four forms.

Because of the wide range of configurations, we recommend that you discuss your specific requirements with our Technical Sales Manager by using the Enquire Now link on the right.

Short-wavelength Low-temperature Pyrometer

Four Optic Configurations

Mikron’s PhotriX ® Series of infrared thermometers can be integrated into diverse applications by using one of the four distinct optical configurations. Optics are suitable for measuring objects in high vacuum, harsh EMI, chemically corrosive and hard-to-access industrial environments. Each of the four collection optics configurations offers unique advantages:

Integrated Lens

  • For viewing a small spot on target
    – from a distance,
    – through the viewport, or
    – through a window
  • Spot sizes as small as 0.5mm
  • Measures as low as 65°C with 700-1650nm spectral response
  • Measures as low as 270°C with 900nm spectral response
  • Standard working distance between 50mm and 2000mm that are factory focused to minimize spot size

Direct Lightpipe

  • Sapphire lightpipe is designed for direct insertion into the process chamber through standard vacuum fittings
  • Measures as low as 30°C with 700–1650nm spectral response
  • Measures as low as 210°C with 900nm spectral response

Fiber Optics to Lens

  • For applications with high ambient temperatures or flammable/combustible hazards. The fiber optics allow the electronics to be safely located separately from the measurement area
  • If mechanical space is limited near the measurement area, then fiber optics can offer more flexible integration and mounting options
  • Measures as low as 65°C with 700-1650nm spectral response
  • Measures as low as 270°C with 900nm spectral response

Fiber Optics to Lightpipe

  • Similar to the case above, this configuration is also considered for applications with high ambient temperatures or flammable/combustible hazards. The use of a lightpipe is usually in conjunction with a process chamber or reactor
  • Measures as low as 60°C with 700–1650nm spectral response
  • Measures as low as 240°C with 900nm spectral response

Typical Applications

  • Low emissivity metals
  • Aluminium
  • Thin-film CIGS solar deposition
  • Thin-film amorphous silicon deposition
  • Laser heating processes
  • CZ crystal growth
  • Optical fibre drawing
  • Induction heating
