A mobile robot can have excellent motors, reliable navigation software, and a powerful processor—and still make poor decisions if its camera does not capture the right visual information.For an autonomous guided vehicle (AGV), warehouse robot, inspection robot, or service robot, the camera lens is not simply a small part attached to the sensor. It determines how much of the environment enters the image, how objects are represented, and how consistently the vision system can interpret what it sees.

An endoscope lens has a difficult job. It must fit into a narrow instrument while producing an image that is useful at a short distance, often in a space where lighting and positioning are tightly constrained.Choosing an endoscope lens is therefore not simply a matter of selecting the smallest available diameter or the widest field of view. A lens that captures a broad scene may show less detail per object. A design optimized for a particular working distance may not keep a much nearer or farther object in acceptable focus. Mechanical limits can also restrict the optical configurations available to the designer.

A thermal camera does not form an image in the same way as a conventional visible-light camera. It detects infrared radiation within a defined spectral band and converts the received signal into a thermal image. The lens must be designed for that wavelength range and matched to the detector and intended application.

A camera project can look perfect on paper.The sensor has the required resolution. The lens has the specified focal length. The mounting thread fits. The budget is approved.Yet the first sample produces disappointing images.The corners are blurry. The image is darker than expected. Focus changes when the camera temperature rises. Or the lens captures a different area of the scene than the engineering team anticipated.

This article explains why camera lenses must withstand temperature changes. A lens is both an optical and mechanical system: barrels, spacers, adhesives, and optical elements expand and contract at different rates, shifting element spacing and focus. Even if nothing breaks, the point of best focus can move, softening images in outdoor installations. Optical materials also change refractive properties with temperature. Athermalization—designing the system so thermal changes compensate—addresses this. Applications like automotive, surveillance, drones, and industrial vision face repeated cycling, so testing must verify maintained optical performance, not just power-on survival. The right temperature specification depends on the actual environment, not a universal rating.

BOSHI Optics has expanded its manufacturing network with a new factory in Suichuan, Ji'an, Jiangxi—its third facility alongside Shanghai and Shangrao. The Ji'an plant covers 15,450 m² with 200+ staff and an annual capacity of ~9 million lens sets, covering optical cold processing to lens assembly. Combined with existing sites, BOSHI now has ~48,000 m² of manufacturing space and ~20 million pieces monthly capacity. Capabilities span lens barrels, optical components, precision molding, coating, assembly, and MTF testing. The company serves security, automotive, and medical lens applications, offering both standard and custom optical solutions for OEM/ODM projects.
