Abstract: A device and methodology for cleaning optical instruments. The device includes a sheath, a wiper mechanism, and an actuator. The sheath attaches to the optical instrument such that the wiper mechanism is in proximity to the lens of the optical instrument. The wiper mechanism includes an blade and an compliant deployment system having first and second curved cross members attached to the blade and sheath such that they bias the blade in a first state where the blade in a deployed position but can deform allowing the blade to transition to a second state in a stored position. The actuator maintains tension on the blade to keep the blade in a second state and when the actuator releases tension on the blade spring energy stored by the deformation of the curved cross members is released transitioning the blade to the first deployed position providing a wipe of the wiper mechanism.
