ULP Fiber-Optic Probes

Fiber-optic Probes are available in a variety of aperture sizes (large aperture, small aperture), lengths, and cable types to meet the exact requirements of your LED test. After selecting a pre-programmed sensor for the desired test and output type, then select a Fiber-optic Probe to cover the physical and mechanical requirements as well as the limitations of your UUT.

  • Probe Diameter: Small Aperture, Wide Aperture, Contacting Tip, Very Wide Aperture
  • Probe Flexibility: Regular, Superflex, Rugged, Rigid
  • Tip Length and Type: Short, Long, Extra Long, Right Angle or Periscope

Single - WA

Single Probe - Wide Aperture

Compared to the Small Aperture Fiber-optic Probes, it is possible to record four times the amount of light. This makes it possible to compensate for weak LEDs and unintentional misalignments in the test apparatus. This is the best choice for end products, e.g. illuminated switches or alphanumeric symbols.

Duplex - SA

Duplex Probes - Small Aperture

Suitable for testing two LEDs sequentially with one sensor. The Fiber-optic Probes are bundled in groups of two per sensor. Accordingly, it is necessary to test sequentially and only one of the two LEDs should light up at the same time. The cost per LED test point will be reduced.

  • Flexible cable: 1 x 250mm length
  • Probe tip diameter: 1.27mm
  • LED distance: d ≥ 1.27mm
  • Probe tip type: stainless steel
  • Air gap: 1 mm

Trident - SA

Trident Probes - Small Aperture

Suitable for testing three LEDs sequentially with one sensor. The Fiber-optic Probes are bundled in groups of three per sensor. Therefore, it has to be tested sequentially and only one of the LEDs should light up at the same time. This reduces the cost per LED test point.

  • Flexible cable: 1 x 250mm length
  • Probe tip diameter: 1.27mm
  • LED distance: d ≥ 1.27mm

Single - SF

Single Probe - Super Flexi

The Superflex Fiber-optic Probes provide increased flexibility for easier access to hard-to-reach LEDs. For test systems where wiring and connection in the test adapter have less space.

  • Flexible cable: 1 x 250mm length
  • Bending radius: ≥ 6.35 mm
