Product Details Supplier Info More products

Laser Components has introduced a range of two-dimensional position-sensing detectors (PSDs) for applications such as distance and height measurement, positional alignment, motion measurement and vibration studies.

The Sitek range of PSDs provides high-accuracy (±0.3 per cent typical non-linearity) readings over areas of up to 45 x 45mm.

The PSDs are also available with ultraviolet or YAG enhancement or as nuclear detectors.

Using suitable lasers, a 100m line-of-sight measuring system can produce a measurement accuracy of 25µm.

Key features and benefits

  • The PSDs are designed to offer higher resolution and speed than CMOS detectors and CCD devices.
  • The Sitek devices feature built-in stray light elimination properties, which increase speed and linearity and reduce erroneous readings.
  • The devices, used in conjunction with PSD electronic evaluation boards, provide an easy-to-connect, easy-to-use system that is ready to be used as a standalone detector or to be incorporated into larger systems.
