Request Information
The confocalDT IFS2404/90-2 90º sensor is designed for precise measurements of displacement, distance, position and thickness. This sensor is equipped with a 90° lens and is therefore ideally suited to installation in restricted spaces. Based on a special lens technology, the confocalDT IFS2404 sensors provide high resolution and a small light spot diameter. They are ideally suitable for applications involving a large number of pieces.

Customer-Specific Modifications

Customer-Specific Modifications

 N/A Application examples are often found where the standard versions of the sensors and the controllers are performing at their limits. To facilitate such special tasks, it is possible to customize the sensor design and to adjust the controller accordingly. Common requests for modifications include changes in design, mounting options, customized cable lengths and modified measuring ranges.Possible modifications
  • Sensors with connector
  • Cable length
  • Vacuum suitability up to UHV
  • Specific lengths
  • Customer-specific mounting options
  • Optical filter for ambient light compensation
  • Housing material
  • Measuring range/Offset distance

Characteristics

Characteristics

 N/A
  • Sensor design from ø12 mm
  • Submicrometer resolution
  • One-sided thickness measurement
  • Distance measurement
  • Extremely small spot size
  • Large tilt angle
  • 1 Average from 512 values at 1 kHz, near to the midrange onto optical flat.
  • 2 RMS noise relates to mid of measuring range (1 kHz).
  • 3 All data at constant ambient temperature (25 ±1 ºC) against optical flat; specifications can change when measuring different objects.
  • 4 All data at constant ambient temperature (25 ±1 ºC) against optical flat; specifications can change when measuring different objects.
  • 5 Maximum sensor tilt angle that produces a usable signal on reflecting surfaces. The accuracy decreases when approaching the limit values.
  • 6 Glass with refractive index n = 1.5 throughout the entire measuring range. In the mid of the measuring range, also thinner layers can be measured.
