What color LEDs does Optomistic Products Universal LightProbes test?

Optomistic Products LightProbes can accurately test almost any LED color, or intensity.  If you are testing an LED that is red, green, blue, yellow/amber, orange or white, our Universal LightProbe Penta sensor will accurately test both LED color and intensity.  If you are testing a "boundary" color (such as a greenish-yellow) the Universal LightProbe Spectra Sensors provide the convenience of a user-assigned visual color, plus intensity test.

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

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.

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

The intensity output of the Universal LightProbe Penta, Spectra and Unicolor sensors will be less than 50mV.  The Universal LightProbe Penta high-sensitivity sensor (HS) should be used for very low intensity LEDs.

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

Wide-aperture fiber-optic probes are specifically 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."  The wide-aperture fiber-optic probes are available with either a contacting or non-contacting tip.

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

The wide-aperture probes can compensate for small fixture misalignment errors. 

Which Universal LightProbe interfaces with a PC or USB port?  

Universal LightProbe Spectra ASCII sensors.
