Abstract
A device and methodology for cleaning optical instruments. The device includes a sheath, a wiper mechanism, and an actuator. The sheath attaches to an optical instrument such that the wiper mechanism is in proximity to a lens of the optical instrument. The wiper mechanism includes a blade and a 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 is in a deployed position but can de-form 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 the second state and when the actuator releases tension on 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.
