The OL 770-LED is a high speed, CCD-based spectroradiometer system optimized to perform all critical measurements of light emitting diodes (LEDs), LED clusters and LED chips. Accessories are also available for testing fnished packages from smaller MR-16, E14, E26/E27 medium screw base lamps to mediumsized E39/40 moguls all the way to 60+ linear ﬂuorescent fxtures. The OL 770-LED was designed for customers who require fast measurement results but not at the expense of quality, color consistency, or precision. The OL 770-LED is accurate enough to characterize LED components for R&D purposes, but economical, lightweight, and portable enough for performing rapid QC checks on the production ﬂoor. The OL 770-LED is fully compliant with CIE Publication 127, as well as LM-79, LM-80 and C78.377.
The OL 770-LED’s control electronics, internal spectrograph, and detector are housed in one rugged, portable enclosure. Its lightweight and small footprint design, relative to larger scanning spectroradiometers, makes it an ideal instrument for use in production environments, especially where portability is needed. The instrument is equipped with both RS-232 and Universal Serial Bus (USB) interfaces, thus a plug-in card for the PC host is not required. The USB interface provides for extremely fast measurements and allows laptops to be utilized.
