    The optical attenuators OAFP-S (OAFP-M), OAGP-S (OAGP-M) are designed to attenuate laser radiation with more than 1:10^3 ratio. The OAFP model comprises a thin zero-order half-wave phaseplate and two mirror polarizers that select the input pulse according to polarization.  This model has been specially developed for pulsed femtosecond radiation (<50 fs) as it introduces as little dispersion to the pulse as possible. For longer pulse durations we offer the OAGP model, which has better transmission ratio as a Glan prism is used to simplify the scheme.
     The attenuator comes in manual (-M) or motorized (-S) modification with USB interface and controller.
