ULP S2 Spectra Sensor
ULP-S2 WBI/V
The Universal LightProbe Spectra Sensor tests each colour (incl. white) and their intensity in the visual spectrum. Spectra Sensors are also well-suited for border colour LED testing as they allow the user to set their own PASS / FAIL colour limits.
Specs
Typical response time
- Capture < 10ms
- T < 100ms total for the output of colour and intensity at the same time
Colour response
- Each LED colour in the spectrum 400 to 700nm and white
- Unique and stable analog voltage output
- LED wavelength = 100*(Vout+4)nm
- White: 3,5V
Output impedance (for intensity and colour)
- Resistance ≥ 2Kohms
- Capacity ≤ 100pF
Intensity
Typical answer for a green PLCC LED tested with a Universal LightProbe Spectra Sensor and a Small Aperture Probe.
- Analog voltage output 0-4V
- Mapping in Millicandelas (mcd)
- CIE Photopic curve-corrected
- For LEDs from 1 mcd to 20,000 mcd
- Also available in High Sensitivity version
