This new, unused but out-of-package S121C power head is designed for general purpose optical power measurements. The S121C is optimized for small thickness to fit in tight spaces. The high sensitive silicon photodiode with large active area in combination with an absorptive ND filter enables power measurements up to 500 mW in free-space and fiber-based applications. A annular IR viewing target allows conveniently centering the measured beam to the active area of the photo-diode. The target absorbs light from 400 to 640nm and 800 to 1700nm. The S121C housing includes a threaded input in axis with the light input aperture that is compatible with any number of Thorlabs threaded accessories. This allows convenient mounting of external optics, fiber adapters, light filters, and apertures. A 8-32 threaded mounting hole is provided to accommodate posts and post holders. The S121C is compatible with the new Thorlabs PM100D and PM100A. A non-volatile memory in the sensor connector contains sensor information data and the NIST and PTB traceable calibration data. Please note that the S121C power meter head is not compatible with older Thorlabs power meter consoles (PM100, PM30, PM300, PM300E, S100).
