Optical imaging device and cap

A near infrared (NIR) light optical imaging device for imaging an object, the imaging device comprising:

• a body,
• at least three optical transceivers located within the body, and
• a device cap, the device cap comprising:
• a bellow support plate comprising a support plate face configured to face a surface of the object to be imaged;
• a deformable bellow sealingly engaged to the bellow support plate, and
• at least three deformable housings, each of the deformable housings being adapted to receive a light pipe and having a tip adapted to contact the surface of the object to be imaged, each of the light pipes corresponding to one of the at least three optical transceivers,
• wherein the deformable bellow has a cross-sectional profile defining a first perimeter rim and a second perimeter rim, wherein the first perimeter rim sealingly engages the bellow support plate.
