Universal LightProbe Sensors


Optomistic Products’ unique Two-Part Solution fulfills almost every LED test requirement you may have.

First, determine your test requirements. For example: LED color and intensity test with an analog output, or, LED ON/OFF status with a digital output, etc.  Then, choose from the range of Sensors listed below to address those requirements.

Second, choose a Fiber-optic Probe to customize the test for specific mechanical requirements and constraints.

S2 Penta Sensors Our most popular Sensor for both ICT and Functional Test. Provides color binning for the 5 main LED colors and white, plus intensity test.  Analog voltage output.


S2 Spectra Sensors: Assign your own color boundaries/bin for any color in the visual spectrum, plus intensity test. Analog voltage output. Best for testing ‘Boundary Color’ LEDs


Spectra USB Sensors: Popular for Functional test, providing color wavelength in nanometers, plus intensity test. Serial digital output via a USB connection to your PC.


S2 Unicolor Sensors: Pre-programmed to test any one of the 5 main LED colors, plus white, providing an analog voltage output relative to the LED’s intensity.


S2 Unicolor Digital Sensors: UnicolorSensorPre-programmed to test any one of the 5 main LED colors, plus white. Digital output.


S2 Blinx Digital Sensors: BlinxdigitalFast ON/OFF status of steady-state or blinking LEDs, up to 15Hz. Digital output.


S2 Ultra High Sensitivity SensorsFor the ON/OFF status test of extremely dim LEDs, down to 0.018mcds. Digital output.


S2 Penta High Sensitivity Sensors: Color binning and intensity test of very dim LEDs. Analog voltage output.
