Infrared cameras can include an infrared sensor and an infrared lens assembly defining an optical axis. A camera can include an inner gear engaging the infrared lens assembly and a focus ring that engages the inner gear. The inner gear can engage the focus ring and the infrared lens assembly such that rotation of the focus ring about its central axis can cause the rotation of the infrared lens assembly about its optical axis, which may be offset from the central axis of the focus ring. The camera can include a sensor can threadably engaging the infrared lens assembly and fixed relative to the infrared sensor such that rotation of the infrared lens assembly causes the infrared lens assembly to move relative to the infrared sensor. The sensor can can support other components such as a visible light lens assembly or a laser within a perimeter of the focus ring.

An add-on lens assembly supporting an add-on lens for a camera includes a locking mechanism actuatable by the user in order to increase the attachment force between the lens and the camera. The add-on lens assembly may include a rotatable lock ring having a cam pin that navigates along a surface of a cam such that when the lock ring is rotated, the cam pin causes the cam to translate axially. Axial translation of the cam may compress a spring within the assembly and increase the attachment force between the lens assembly and the camera. The increased force between the add-on lens assembly and the camera may provide additional support for large or heavy assemblies.

A laser line generation device includes a unitary lens structure and a laser emitter. The unitary lens structure includes an aspheric surface, a conical surface, and a side surface. The conical surface tapers inwardly toward the aspheric surface to an apex of the conical surface that is opposite an interior side of the aspheric surface. In operation, the laser emitter emits light rays toward the unitary lens structure, and the light rays pass through the aspheric surface into the unitary lens structure, reflect off of the conical surface, and exit the lens structure through the side surface. The light rays exiting the unitary lens structure may be substantially perpendicular to the light rays entering the unitary lens structure.

Methods and systems for mounting a lens in a lens cell. The system may include a spindle assembly including a motor and a spindle, which may be an air bearing spindle, a passage within the spindle and an opening at the end of the passage at the surface of the spindle head, a vacuum source connected to the passage of the spindle to create suction at the opening, a stage configured to securely receive a lens mount with a lens cell such that a central axis of the lens cell is coaxial with the axis of rotation of the spindle, a micropositioner configured to reposition the lens on the spindle head, and a motion gauge configured to detect eccentric rotation of a lens as lens motion when the lens is positioned on the head of the rotating spindle.

Lens assembly method and systems

Doublet lenses and doublet lens assemblies, and methods of assembling doublet lenses and assemblies, including a first lens having a convex surface and a concave surface, the concave surface comprising a peripheral portion and a central portion, and a second lens having a convex surface and a concave surface, the concave surface comprising a peripheral portion and a central portion. The peripheral portion of the first lens abuts the peripheral portion of the second lens with an airspace between the central portion of the first lens and the central portion of the second lens. The peripheral portions of the first and second lenses are shaped to fit together in a mating relationship which prevents sliding of the first and second lenses relative to each other in a radial direction after the lenses are brought together.

Self-aligning doublet lens assembly

A lens assembly for a camera including a first lens mounted to a base portion, and a second lens mounted to a lens frame, where the first lens and the second lens are positioned co-axially along a central axis. The lens assembly includes a linear guide system for maintaining alignment of the first and second lenses. An embodiment of the linear guide system includes a first elongated element elongated along a longitudinal axis extending therethrough, parallel to and offset from the central axis. The elongated element may support and guide the lens frame for linear movement along a linear path parallel to the central axis. Some embodiments of the lens assembly include a second elongated element or rotation restriction element.
