Sensors

Penta: Choose Penta to save processing time - provides the test of any one of the five LED visual colors, plus white, and intensity, with built-in color binning, eliminating the need to convert LED wavelength to visual color in the ATE software 

Spectra: Choose Spectra to test boundary colors or whenever you need to assign your own "PASS/FAIL" limits; provides the test of LED color wavelength, including white LEDs, as analog voltages proportional to wavelength in nanometers; also provides intensity test

Unicolor: Choose Unicolor to test any single color LED for correct color and intensity with analog voltage output

Spectra ASCII/USB: If your application requires a PC interface, the Spectra ASCII with a programmed USB Interface Cable is the perfect choice - provides the test of an LEDs intensity, and color wavelength, with an ASCII-formatted serial digital data output 

Unicolor Digital: Choose Unicolor Digital to test a single color LED, with a digital output, for the color test (no intensity) of any single LED color, including white LEDs, as a one-bit, pass/fail digital output  

Blinx: Choose Blinx for Blinking LEDs to test for the on/off status of blinking LEDs up to a rate of 15Hz

Fiber-Optic Probes

Test Closely-spaced LEDs:  Choose 1.2mm diameter fiber-optic probes with non-contacting tips

Test for More Refined Intensity Measurement: When intensity measurement is critical, choose an insulated, contacting spring-tipped probe to eliminate variations in intensity response, available only with a 3.4mm diameter contacting diameter tip

Test Three LEDs with a Single Sensor - Significant Cost Savings: Choose the popular "Trident" for the sequential test of 3 LEDs with one sensor available only with a 1.2mm diameter non-contacting tip

Test Dim LEDs / Compensate for Misalignment Errors:  Choose wide aperture fiber-optic probes which allow 4x the amount of light input as small-aperture probes available with either a 2.7mm diameter non-contacting tip, or 3.4mm diameter contacting tip

Test Side-Facing LEDs: Choose the "Periscope" fiber-optic probe, designed to test side-facing LEDs, available only with a 2.7mm diameter non-contacting tip

Install without Clamps: Choose rigid, stainless-steel encased probes, available with either a 2.7mm diameter non-contacting tip, or 3.4mm diameter contacting tip

Test Difficult to Access LEDs: Choose super-flex cables which allow for a tight bends in the cable, available with either a 2.7mm diameter non-contacting tip, or 3.4mm diameter contacting tip
