OptoSigma OSMS-60-ND Stepper Driven Variable Reflective ND Filter

OptoSigma OSMS-60-ND is a stepper-driven, motorized variable reflective neutral-density filter that delivers precise attenuation across 400–2000 nm. Its motorized adjustment provides continuous ND control without removing or swapping filters, supporting repeatable settings in optical configurations. The device covers visible through shortwave infrared wavelengths, enabling light-level tuning for experiments and measurements that operate within 400 nm up to 2000 nm. As a reflective ND element, it provides controlled transmission across the spectral range to accommodate light-level management in optical setups.
