Request InfoAsahi Spectra Co. Ltd.Linear variable neutral density (ND) filters are available from Asahi Spectra Co. Ltd. Their optical density continuously varies from 0.04 to 5.0 via proprietary monitoring technology. Applications include precise adjustment of laser light intensity. Fashioned from a quartz substrate, the filters measure 100 × 50 mm. A circular ND filter also is available, with the same varying optical density.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 10/2/2023C- & L-band Optical Network TestersThe WaveMaker™ 4000A, WaveShaper® 1000B, and WaveShaper® 4000B from Coherent are instruments made to test optical networks.
