Slit lamps are a common ophthalmic instrument used for examining the ocular anterior segment by projecting a rectangular beam of light onto the eye. Conventional slit lamp configurations require the patient to stabilize themselves using a chin rest and forehead band limiting access to patients who are mobility impaired. We developed a slit lamp module for a robotic arm to allow for autonomous imaging of a slit on the eye of individuals without physical head stabilization at a working distance of 125 mm. Here we describe the optical performance of the custom slit lamp module and present autonomous aligned imaging of a corneal phantom mounted in a mannequin head.
