The D7 series of cosine-corrected transmission diffusers<\/strong> offers high efficiency and near-perfect cosine response in a variety of configurations suitable for a range of applications and instruments.<\/span>\u00a0<\/span><\/p>\n

Including a high-performance diffusing element, each diffuser is optimized to minimize cosine errors and is supplied with a calibration certificate. Available for use with FOP series fiber bundles or SMA fiber, the D7 includes an M6 threaded hole for mounting in optical systems.<\/span>\u00a0<\/span><\/p>\n
