Industrial endoscope camera overview Industrial endoscope camera is a precision instrument used for non-destructive testing, widely used in internal structure inspection and fault diagnosis in various industries. It uses optical imaging technology and electronic signal processing to enable operators to observe the internal surface structure or working status of the object easily and accurately without destroying the surface of the object being inspected.   Working Principle   Optical Imaging Optical imaging is to use a lens to collect the image information inside the inspected object, and then transmit the image to an external display through a fiber optic light source. The specific steps are as follows: 1. Provide light source: provide light source illumination through a lamp tube. 2. Image acquisition: light passing through the inside of the object is imaged through a lens. 3. Image transmission: the imaged image is transmitted to an external display through an optical fiber. Electronic Imaging Electronic imaging is to use high-definition imaging devices such as CCD or CMOS to collect the image information inside the inspected object, and then transmit the image to an external display through a cable. The specific steps are as follows: 1. Image acquisition: The image information inside the inspected object is collected through imaging devices such as CCD or CMOS and converted into electrical signals. 2. Image transmission: The electrical signal is transmitted to an external display through a cable. The working principle of the industrial endoscope camera combines optical technology and electronic technology, allowing operators to observe the details inside the inspected object in real time. Different industrial endoscopes may use different imaging technologies and components according to their design and application requirements. Host image processing The host is equipped with a high-performance processor, such as the RK3588 high-performance processor, which adopts an advanced three-level superscalar processing architecture and is equipped with ARMCortex-A76 and Cortex-A55 cores to efficiently process image data transmitted from the camera.

Strategies to improve night shooting effects When night shooting effects are not good, you can indeed consider using additional fill lights to improve image quality. Here are some effective strategies and suggestions: The size of the aperture Directly affects the amount of light entering the camera, thereby affecting the night shooting effect. A larger aperture (such as F/2.0) can increase the amount of light inlet and improve image quality, but it can also cause overexposure during the day and glare problems when entering and exiting the tunnel. The function of fill light Fill light Fill light is an effective tool to improve night shooting effects.Most driving recorders are equipped with LED fill lights. By correctly installing and adjusting the angle, the light reflected by the windshield can effectively avoid affecting the shooting effect. Selecting camera configuration Selection of high resolution and high performance cameras can also significantly improve night shooting effects.For example, a 1296p ultra-high definition camera can provide clearer images.  Optimize light conditions. Try to choose a place with sufficient light to shoot to improve the quality of night shooting. At the same time, keep the lens clean and clean the dirt regularly to ensure that the light can fully enter. Shooting Tips When shooting night portraits, it is recommended to use a constant light source instead of a flash, because the constant light source can provide better control and more natural light effects. 

Overview of Optical LensesOptical lenses, also known as camera lenses or photography lenses, abbreviated as lenses, are an important branch of the optoelectronics industry and an indispensable component in machine vision systems. It is generally composed of precision hardware, plastic parts, lenses, apertures, drive motors, sensors, and other optical and electrical components, as well as a lens barrel. Optical lens is an important core component in optical imaging systems, which focuses the subject to be photographed onto film or image sensor chips by utilizing the principle of optical refraction. The resolution, contrast, and various aberrations of imaging are the standards for measuring the quality of optical lenses, which affect the quality of imaging, algorithm implementation, and effectiveness. Main parameters of optical lensesThe main parameters of optical lenses include focal length, viewing angle, aperture, resolution, etc. The focal length determines the magnification and field of view of the lens. The field of view refers to the range of scenes that the lens can capture. The aperture controls the amount of light entering the lens, while the resolution affects the clarity of the image. Classification of optical lensesOptical lenses can be classified according to different standards: Classified by focal length and viewing angleWide angle lens: With a viewing angle of over 90 degrees, it is suitable for capturing close range and wide range scenery, and can increase the spatial depth of the photographic image.Standard lens: With a viewing angle of around 30 degrees, it has a wide range of applications and is usually used for daily shooting.Telephoto lens: with a viewing angle of less than 20 degrees, the focal length can reach tens or hundreds of millimeters, suitable for capturing distant scenery.Zoom lens: The focal length of the lens is continuously variable, and the focal length can be changed from wide-angle to telephoto, providing greater flexibility.Pinhole lens: used for concealed observation, often installed in places such as ceilings or walls.Classified by structureFixed aperture fixed focus lens: simple structure, cheap price, but the aperture cannot be adjusted.Automatic aperture fixed focus lens: An automatic aperture adjustment function has been added to the fixed aperture fixed focus lens.Manual zoom lens: The focal length can be adjusted by manually adjusting the zoom ring of the lens.Automatic zoom lens: both focal length and aperture can be automatically adjusted, providing higher convenience. Electric three variable lens: aperture, focal length, and focus can all be adjusted, providing maximum flexibility.Application fields of optical lensesThe application fields of optical lenses are very wide, including mobile phones, cameras, car lenses, LiDAR, machine vision, AR/VR, etc. With the advancement of technology and the development of social economy, the application of optical lenses in these fields continues to expand and deepen, and the future will present a more intelligent development trend. In summary, optical lenses are complex and important optical systems, and their design and manufacturing have a crucial impact on imaging quality and application effectiveness. With the continuous advancement of technology, the design and production technology of optical lenses are also constantly developing to meet the growing market demand and technical requirements.

OverviewPrime lensFixed focus lens refers to a lens with only one fixed focal length, one focal segment and field of view, and no zoom function. Its design is simple, the focusing speed is fast, and the imaging quality is stable. Common fixed focus lenses have focal lengths of 24mm, 35mm, 50mm, 85mm, etc. High end photography enthusiasts also choose fixed focus lenses with long focal lengths of 200mm, 400mm, 600mm, 800mm, etc. Zoom lensA zoom lens is a camera lens that can change the focal length within a certain range to obtain different widths of field of view, different sizes of images, and different ranges of scenery. It can change the shooting range by adjusting the focal length without changing the shooting distance, which is beneficial for image composition. Common zoom lenses in daily life include wide-angle focal lengths (such as 11-24mm, 14-24mm, 16-35mm, etc.), standard focal lengths (such as 24-70mm, 24-85mm, 24-105mm, etc.), and telephoto focal lengths (such as 70-200mm, 70-300mm, 100-400mm, etc.) Focal length adjustment methodZoom lens: By adjusting the distance between the lenses in the lens group, the focal length of the lens can be changed within a range. For example, the common 24-70 lens has a focal length that can be adjusted between 24mm and 70mm. It is easy to operate and can change the framing range without twisting the lens while standing.Fixed focus lens: The focal length is fixed, and if you need to change the content of the image, you have to rely on the camera's forward and backward movement to achieve it. This is also the origin of the saying "zoom basically depends on movement".Aperture characteristicsZoom lens: Adjusting the focal length usually causes changes in the aperture, such as the Canon EF-S 18-135mm f/3.5-5.6 STM IS. At 18mm, the maximum aperture is 3.5, and when turned to 135mm, the maximum aperture becomes 5.6. The maximum aperture of current constant aperture zoom lenses is generally around 2.8. If the aperture is even larger, it requires a larger volume and more complex optical path design, and the price is also very expensive. For example, the RF28-70mm F2L USM is priced at 22499 yuan.Fixed focus lens: The structure is relatively simple, and within a certain price range, the optical quality is generally better than that of zoom lenses. It is also easier to manufacture large apertures, such as 1.4, 1.2, or even 0.95, which are more common in fixed focus lenses.weightZoom lens: Due to its complex internal structure, it requires a structure that accommodates zoom motion. If it is an electric zoom lens, it also needs to add related parts such as a motor, so the overall size and weight are relatively large, and handheld shooting is prone to shaking.Fixed focus lens: simple structure, usually not too heavy, convenient for handheld shooting.AppearanceZoom lens: Generally, it has an additional focus ring compared to fixed focus lens.Fixed focus lens: It has a relatively short appearance and usually only has one zoom ring.priceZoom lens: Generally priced higher, such as Canon's full frame red circle zoom lens, which costs around 10000 yuan for 24-70 f/28000.Fixed focus lens: The price range is wide, and there are cheaper options, such as the non professional 50mm f/1.8, which costs less than 700 yuan; There are also professional fixed focus lenses with higher prices, but overall, under the same optical quality, fixed focus lenses have a price advantage compared to zoom lenses.Imaging qualityWithin a certain price range, the imaging quality of fixed focus lenses is often better. There is a saying that "a dog's fixed lens wins over a cow's variable lens", which means that cheap fixed focus lenses may also have better optical quality than expensive zoom lenses.
