Spiricon's new low-cost SP-1550M camera, at $1,995, measures the output of optical telecom devices from 1460 nm to 1625nm. Coupled to the LBA-PC series beam analyzers, view mode-field patterns of fibers, laser diodes, LEDs, and VCSELs in real-time. Measure NA, MFD, Aeff as well as pointing direction, component alignment, and device divergence. The camera is a high-resolution CCD sensor with a phosphor coating that up-converts NIR radiation to visible, detectable by the CCD. The LBA-PC beam analyzers correct for nonlinearity in the up-conversion process, which then produces accurate measurements and correct beam profiles.
