Lenses are essential imaging elements of any camera device. They define the intensity of the signal received from an image sensor. Indeed, one has to match up sensors and lenses to get the best from the image. Indeed, the selection of lenses for industrial applications depends on their specific applications.
Simultaneously, the lens comes with different specifications. These are view field, size of a sensor, working distance, image resolution, field depth, operating and lighting conditions. Here comes the role of a Linos Lens System, which has obtained a huge demand in high-precision industrial applications.
Structure and Dimensions of Linos Lenses
Many industries today use Linos focus Ronar lenses for diverse applications. These lens systems come in optical glass of 532nm and 1064nm. Besides, the lens systems have covering focal lengths from 58nm to 122 nm. Moreover, a précised three-lens elemental design makes sure of flexible exchange of lenses without any need for adjustments. A Focus Linos Lens System has a relatively high optimization to perform high precision applications.
Other Considerations to Choose Lens for Industrial Applications
Selection as Per Lens Resolution
One has to consider the accuracy to observe or measure any object to choose the resolution of an industrial lens. The pixel accuracy of a camera must be equal to the single direction resolution of the camera. In this case, the resolution of a camera in a particular direction is equal to the size of the view field in the respective direction to achieve accuracy theoretically.
On the other hand, if a particular view field is 5nm and the lens theoretical accuracy is 0.2mm, its single direction resolution equals 250 i.e. 5/0.02. After this, users have to consider the output of an industrial camera. Accordingly, a high resolution helps in posture observation or analysis of machine software. This means one has to consider the resolution of the display while choosing an industrial camera for welding, cutting, and drilling applications.
Camera Frame Number
When the object to measure is in motion, users have to select the industrial camera lens, which has a high frame number.
Match of Various Lenses
Whether individuals select a Linos Lens System or any other type of lens, they have to consider the size of the installed sensor chip. Accordingly, the chip size must be similar to the size of the lens. Simultaneously, the lens must match with CS mounts or C mounts as well.
Photosensitive Device Size
People have to select the lens based on the size of a photosensitive device. If a photosensitive chip is 2 inches or 3 inches, one has to choose the lens corresponding to its imaging coil. On the other side, ½ inches or 1/3 inches of lenses show a big dark angel. Other than that, users have to choose the lens according to its focal length i.e. the one, whose view field is relatively large as compared to the range of observation.
Matching of Field Depth and Light Environment
One can choose a relatively small aperture in areas with enough light source illumination to increase the field depth. Doing so will increase the clarity of the shooting image. In contrast, places with limited light must have a slightly large aperture or a chip with high sensitivity.
Conclusion
Overall, the right pair of lenses is essential to accomplish each of the industrial projects. Hence, users have to consider various things while choosing a specific lens system.
