Linear Variable Filter

The Thin-film based tunable filter is an ideal candidate for telecom application, especially for DWDM system, on account of its low insertion loss, flat-top transmission spectrum, and excellent thermal stability. With new masks and the optical monitor system to control the coating uniformity during the whole process, Lightwaves2020 successfully makes high-quality step motor controlled 50GHz Linear Variable Filters (LVF) with high yield.
Excellent thin-film filter quality aside, LVF also has uniform tuning spectrum over the operation wavelength range and small package size. The vibration-free package and electronics control circuit is also provided. The wavelength setting repeatability is < ±50pm. Undoubtedly, Lightwaves2020’s thin-film based tunable filter family is best solution for DWDM system application.
