IFS 2405

confocalDT IFS 2405

confocalDT IFS 2405 are confocal displacement sensors for extremely precise applications. These confocal chromatic sensors offer large offset distances and tolerate tiltings. They are used for common measurement tasks and are in addition suitable for one-sided thickness measurement of transparent materials. New: This sensor is now also available with a measuring range of 6 mm which is ideally suitable for measurements from a safe distance to the target.

  • Measuring ranges (mm):
    0.300 | 1 | 3 | 6 | 10 | 28 | 30
  • Linearity max. 0.15 µm
  • Resolution max. 0.01 µm
  • Distance and one-sided thickness-measurements
  • High sensitivity

IFS 2406

confocalDT IFS 2406

The confocal IFS2406 series stands out due to its compact design and high precision. As well as distance measurements on reflecting or transparent surfaces, the sensor can also be applied in one-sided thickness measurement of transparent film, plates or layers. Due to its axial and radial measuring directions, the IFS2406-2,5 sensors are suitable for vacuum applications and extremely versatile in terms of its use.

  • Measuring ranges (mm):
    2.5 | 3 | 10
  • Linearity max. 0.75µm
  • Resolution max. 0.024µm
  • Distance and one-sided thickness measurement
  • Small light spot
  • Vacuum compatible sensor

IFS 2430


The confocal chromatic confocalDT IFS2403 measurement sensor combines the benefits of two successful confocal design concepts. With an external diameter of 8mm, this sensor is as compact as the confocalDT IFS2402 miniature sensor series. However, due to its larger digital aperture, it can receive significantly more reflected light than the smaller 4mm diameter version. These sensors are also available as radial or axial model.

  • Measuring ranges (mm):
    0.4 | 1.5 | 4 | 10
  • Linearity max. 0.3µm
  • Resolution max. 0.016µm
  • Sensor with hybrid design
  • Housing made from steel
  • Increased offset distance
  • Axial and radial measuring direction

IFS 2407-0-1


The confocalDT IFS2407-0,1 sensor is designed for high precision measurements of distance, roughness and thickness. The high numerical aperture (NA 0.8) enables the thickness measurement of transparent objects with a minimum thickness of 5 µm. Another light-intensive sensor model featuring NA 0.7 is specially designed for high speed processes.

  • Measuring range (mm): 0.1
  • Linearity: max. 0.05 µm
  • Resolution: max. 3 nm
  • Ideal for distance and roughness measurements
  • Light-intensive sensor variant for high speed processes available (NA 0.7)
  • Small measurement spot size: 3 µm
  • High sensitivity and large tilt angle
  • Thickness measurement of transparent objects from 5 µm
