FAQs

Which Optomistic Universal LightProbe will best suit my specific LED test application?

  • Which is Best For Your Test will help you determine which sensor and fiber-optic probe will achieve the best results for your specific application. If you still have a question regarding which Universal LightProbe is best for your application, please contact us.

The LED under test is very bright – how can I be sure I am receiving an accurate test result?

  • When an LED is too bright, the intensity output of Universal LightProbe Penta, Spectra and Unicolor sensors will be at 4.1 volts. Optomistic Products provides a low-sensitivity option that can be used with any of our Universal LightProbe sensors. Refer to the Application Note on Sensor Sensitivity Ranges, or contact us for more detail on sensor sensitivity and the best sensor for your specific LED test.

The LED under test is very dim – how can I be sure the LightProbe will test it accurately?

  • When an LED is too dim, the intensity output of the Universal LightProbe Penta, Spectra and Unicolor sensors will be less than 50mV. The Universal LightProbe Penta High Sensitivity (HS) should be used for very low intensity LEDs and the Ultra High Sensitivity Sensor can be used to test LEDs that are extremely dim, including very low light-level LED-illuminated action-indicator switches. Refer to the Application Note on Sensor Sensitivity Ranges, or contact us for more detail on sensor sensitivity and the best sensor for your specific LED test.

Which LightProbe is best for testing finished-product displays, or LEDs connected to high-loss plastic “light-pipes”?

  • Wide-aperture fiber-optic probes are designed for testing finished-product displays such as illuminated switch alpha-numeric icons, and very low-intensity front panel status indicator lights incorporating high-loss, plastic “lightpipes.”

Which Universal LightProbe is best for compensating for small misalignment in a fixture?

  • The Wide-aperture non-contacting fiber-optic probes can compensate for small fixture misalignment errors, as they allow in 4x the amount of light as small-aperture probes and can be set further away from the LED under test to increase the field of view of the sensor.

Which Universal LightProbe interfaces with a PC or USB port?

Are Universal LightProbes compatible with Agilent 3070 Test Systems?

  • There are several advantages to using Universal Light Probe Sensors in your ICT applications. For a full article demonstrating 3070 Library Development techniques with any configuration LED, from a single LED to multiple LED packages, please contact us.
