The OL 770-LED - High Speed LED Measurement System for Light Emitting Diodes
Software | Measurement Accessories | Information Request
Optronic Laboratories' NEW LEDMeasurement System is a high-speed, multichannel spectroradiometer capable of over 25 spectroradiometric scans per second. Unlike stand-alone radiometers and photometers currently available for individual measurements, the OL 770-LED performs all critical measurements of LED components including optical power, color and goniometric measurements. The OL 770-LED was designed in accordance with and is fully compliant to CIE Publication 127 Condition A and Condition B.
The OL770-LED is a highly accurate, high-speed LED measurement tool, developed to meet the needs of R&D, Production and Quality Assurance. It provides research-grade test and measurements but was designed using economies derived from all disciplines of hardware, firmware and software. Typical measurements provided by the OL770-LED Measurement System are:
- Total Radiant Flux (Watts)
- Total Luminous Flux (lumens)
- Total Spectral Flux (Watts/nm)
- Total Power (Watts)
- Dominant Wavelength
- Spectral Purity
- Correlated Color Temperature
- Peak Wavelength
- Color Rendering Index (CRI)
- ChromaticityCoordinates
- Spatial Radiation Measurements delete
- Half-Bandwidth
- Averaged Luminous Intensity (lumens/sr)
- Averaged Radiant Intesity (Watts/sr)
In addition, each of the following LED measurements can be performed as a function of view angle:
- Maximum intensity
- Chromaticity values
- Tristimulus values
- Lab/Luv values
- CRI
- Relative power
- Peak wavelength
- Dominant wavelength
- Half bandwidth
- Color temperature
- Purity
- Power
Designed by and for LED Professionals, the OL 770-LED features:
- Extremely fast LED measurements. Over 25+ spectral radiometer scans per second.
- High-speed USB interface.
- Windows® compatible software, LabVIEW™ Drivers, SDK and ActiveX™ Controls.
- Ideal where instrument portability is needed.
- Research-grade measurements at a fraction of the cost of bench-bound instruments.
- Fully compliant to CIE Publication 127Conditions A and B.
