概要（Overview）

The high-performance Redstone™ OSA305 is designed for applications that require higher optical resolutions or sensitivities than our general-purpose OSA20xC instruments can offer. To accommodate detailed measurements over a wide wavelength range, the Redstone features two detectors and a 2.0 GHz (0.0625 cm-1) spectral resolution, as well as an improved noise floor relative to the previous generation and a 40 dB optical rejection ratio. This OSA also includes BNC inputs to allow for externally triggered spectrum acquisition.
