Abstract: The present disclosure is related to an imaging camera including a filter wheel. The filter wheel includes a main body including a plurality of receptacles and a plurality of wedges. Each of the wedges is attached to one of the plurality of receptacles. Each of the wedges includes a receiving orifice to a filter. The main body of the filter wheel includes an adapter configured to receive an actuator to actuate the filter wheel. Each wedge is removably attached to one of the plurality of receptacles. The filter wheel is configured to rotate around a central axis of the main body.

Abstract: The present disclosure provides an apparatus including a lens housing coupled to a lens assembly, a first lens disposed in a first end of the lens housing, a lens holder disposed in a second end of the lens housing, a lens aligner coupled to the lens assembly, and an optical element. The optical element is insertable laterally into the lens assembly to adjust a transverse position of the first lens and the second lens based on a thickness of the optical element to align a first axis of the first lens and the second lens to a second axis of a third lens positioned in the lens assembly for imaging an eye.

Abstract: The present disclosure provides an apparatus that can be attached to a tip portion of an eye-imaging device including the lens. The apparatus includes an annular base having an orifice having a first end and a second end. A contact member may be disposed adjacent the second end of the annular base. The contact member may include a contact surface having a geometry that is configured to fit on a tip of an eye-imaging device. For example, the contact surface may include a tapered region that matches the profile of a tip of an eye-imaging device. The tapered region may provide a frictional fit with a tip of the eye-imaging device such that the contact surface is flush with the surface of the tip. A solution can be deposited in the apparatus and onto a lens surface after it is attached to the tip of the eye-imaging device. In this way, the apparatus prevents any solution from leaking to other areas of the eye-imaging device to clean the lens surface of the eye-imaging device.

Abstract: The present disclosure provides an apparatus, system, and method for positioning and retaining a specimen for imaging. The apparatus provides a low-profile stand that incorporates multiple functionalities without occluding the imaging path of an imaging device. The apparatus includes a stand having six degrees of freedom of movement in three-dimensional space. The apparatus includes a base member and an upright member extending from the base member. The apparatus includes an adjustable arm including a pivotable stand. The apparatus may include integrated circuitry for heating and sensors to detect various features of a specimen, including blood oxygen, heart rate, blood pressure, respiration rate, or combinations thereof. Additionally, the apparatus includes an integrated fluid delivery system for delivering a fluid to a specimen without occluding the imaging path of an imaging device or restricting movement of the stand.

Abstract: The present disclosure is related to a system and method for adjusting the illumination intensity of an imaging device. The system includes an imaging camera including a light box. The outer surface of the light box includes a first set of magnets. The imaging camera includes a light guide configured to provide light to the light box. A focus assembly including a focus lens is disposed at an end of the light guide. An adjustable collar may be disposed around the focus assembly. The collar includes a second set of magnets disposed on a rear face of the main body. One or more set screws are disposed on the main body of the collar. The collar is configured to move along the length of the focus assembly and can be secured to a position on the focus assembly via the set screws.

Abstract: The present disclosure provides an eye-imaging training apparatus including an actuator to articulate one or more movable eyeball members. The eye-imaging training apparatus provides a caregiver a training tool for practicing various eye-imaging techniques that simulate or mimic natural and animal-like eye movement. For example, the eye-imaging training apparatus may include an eyeball member that can move in multiple directions to simulate human-like eye movement. The eye-imaging training apparatus can train a caregiver to practice, for example, aligning an eye-imaging camera, calibrating the eye-imaging camera (e.g., determining the desired optical parameters), and retracting eyelids for eye-imaging. The present disclosure is also related to systems and methods for eye imaging using an eye-imaging training apparatus.
