Variable Wheel Attenuator 10WA168 is a basic model with 4 filter-set wheels. Each wheel contains 4 filter mounts each of Ø20 mm with clear aperture of Ø18 mm. Each filter mount is inclined by 4°to avoid retroreflections. Each wheel has 4 fixed positions. You can use any of these 4 filter positions as an optical axis. The back and front panels do not obscure them. Both panels have 1"-32 threaded holes (C-Mounts). Additionally you may order standard connecting adapters 10AR168, 10A168 and 10R168. Custom adapters are available. Variable wheel attenuator mounts through M6 hole in the bottom plate.
