S2 Penta Sensors


Optomistic Products’ best-selling Sensor, the ULP S2 Penta Sensor Data Sheet, is relied upon for its versatility in accommodating most LED color and intensity test applications.

The Universal LightProbe S2 Penta Sensor features built-in color binning – testing any of the five main LED colors, blue, green, yellow/amber, orange, red, and also white, by providing a unique voltage output for each color. The color output is independent of intensity, which saves valuable processing time.

Universal LightProbe S2 Penta Sensors also test a wide range of LED intensity, from dim to bright LEDs, without adjustment, providing an analog voltage output corresponding the the LED’s luminous intensity in milicandelas.

For very dim or very bright LEDs, High-Sensitivity and Low-Sensitivity S2 Penta Sensors are available.

In cases where the LED color under test is a “boundary color” and does not fit into the five prescribed visual colors on the S2 Penta Sensor, we recommend our S2 Spectra Sensor
