Giant Union City, you know the cause of the camera lens installation error
In security monitoring, the construction and installation techniques of the lens are not unfathomable. However, due to various reasons during the construction process, lens installation and installation errors are common, resulting in damage to the lens structure or circuit. So, what are these common problems? What is the following list?
Lens Adapter Ring assembled in the wrong order <br> <br> Lens Adapter Ring assembly sequence is the largest engineering staff in the blind spot on the lens mount, and the resulting direct consequence of damage to the lens. Because the C and CS adapter rings are used in lens mounting, many engineers often lock the adapter ring first with the camera, then lock the lens into the adapter ring, and some of the lenses will be designed. With a sliding structure that matches the back focus of the camera or the mechanical back focus adjustment of the release screw on the camera, these adjustments require that the lens be rotated on the mating ring or driven with the mating ring to achieve the best focal length Clear point. However, due to the sequencing error when the engineer assembled, the adapter ring is deadlocked on the lens side. As a result, in the absence of automatic back focus (ABF) function, loosening the mating ring not only fails to adjust the back focus, but also causes the thread teeth to wear out due to improper force, or the screw thread on the plastic material on the lens is twisted. Broken.
Lens assembly is not coated with gloves cause damage <br> <br> in the lens assembly, construction engineers most frequent fault that is not wearing gloves or protective coating causing damage. Due to the lack of protection lens (installed with lens protection cover for installation) and the awareness of careful protection and careful handling of precision equipment or optical components during construction, some engineers often find their fingerprints on the lens surface when the lens is assembled. Or other dirt. Experienced engineers will use appropriate chlorine dioxide and wipe cloth or deerskin to wipe, but some people still choose to use a piece of clothes or wipe with improper paper towels for the sake of convenience, not only coating the lens lens surface. Destructive, but also hurt the video screen and the lens "negative."
When the lens mounted on the protective cover is not properly installed left window <br> <br> powered lens pitch, is most likely to be inadvertent lens mounted on the protective cover is not appropriate to leave the window pitch. When engineers do depth of field or focal length adjustment after construction, they sometimes find that the picture actually sees the image reflected by the camera or the lens itself on the protective cover. At this time, even if the depth of field (ZOOM) or the focus adjustment (FOCUS) is used, the picture twisting cannot be changed. An inexperienced engineer mistakenly believes that the camera itself has not been adjusted, but it is due to the fact that the lens is installed in the protective cover with the wrong spacing.
<br> <br> lens assembled in the absence of adequate protection under the lens assembly process, most of the engineering staff will carefully assembled lens. The price of the lens is not cheap, and the lens is damaged due to slight carelessness. However, some engineers neglect the protection when assembling cameras and lenses, and even choose to perform on site. In the absence of other protective measures such as protective cushions, damage to the lens surface, damage to the internal aperture shutter sheet, or adhesion of sand to the lens can easily occur.
Auto Iris Lens assembly error <br> <br> welding connection line at the manufacturer's efforts lens, the lens is achieved most types of pre-processing and joint line, a result similar to the error caused by the welding line of the servo motor burnout lens no longer exist. However, due to the presence of some electric lenses on the delivery or on-site protection cover, engineering personnel still need to understand and be familiar with these wiring and fine-circuit welding techniques. The author once discovered that the accident of welding and short-circuiting of the auto iris drive circuit joints of all lenses occurred in a project, which caused great losses and cost consumption for the engineering works. As an engineering company, it was necessary to prevent such problems from happening.
