Devices systems and methods for alignment of lens assemblies within a chassis

An imaging apparatus comprising:

• a housing having a window;
• a chassis positioned inside the housing, the chassis having a cavity and a slot extending through a cavity wall, the cavity wall defining at least a portion of the cavity;
• an imaging sensor positioned fixedly relative to the chassis;
• and
• a lens assembly having a protrusion, the lens assembly being positioned within the cavity such that the protrusion is positioned within the slot, the lens assembly being further positioned between the imaging sensor and the window,
• wherein the lens assembly is fixedly secured to the chassis only via a hardened adhesive.

A barcode reader comprising:

• a housing having a window;
• a chassis positioned inside the housing, the chassis having a cavity and a slot extending through a cavity wall, the cavity wall defining at least a portion of the cavity;
• an imaging sensor positioned fixedly relative to the chassis;
• and
• a lens assembly having a protrusion, the lens assembly being positioned within the cavity such that the protrusion is positioned within the slot, the lens assembly being further positioned between the imaging sensor and the window,
• wherein the lens assembly is fixedly secured to the chassis only via a hardened adhesive.

A chassis for use in an imaging apparatus having an imaging sensor positioned fixedly relative to the chassis and a window, comprising:

• a cavity;
• a slot extending through a cavity wall, the cavity wall defining at least a portion of the cavity;
• and a lens assembly having a protrusion, the lens assembly being positioned within the cavity such that the protrusion is positioned within the slot, wherein the lens assembly is fixedly secured to the chassis only via a hardened adhesive;
• wherein the protrusion includes a flange, the flange extending longitudinally along a body of the lens assembly, the flange having a first flange portion, a second flange portion, and a cutout separating the first flange portion and the second flange portion.
