Sequential Shutter function

Sequential Shutter is a function that acquires subject images under multiple shooting conditions.
For example, it is used to obtain multiple images with varying exposure times, gain, and image offsets.
By combining it with Trigger Mode, you can switch between multiple pre-programmed camera settings for each frame upon trigger input, allowing for versatile and dynamic image capture.

Which lens should I use to capture this image

Machine vision requires a photographic lens to project an image of an object onto a camera’s image sensor.
Its selection method is described in our product brochures and on our website as well as in commercially available books and trade journals. However, we receive many questions about the relationship between a field of view (FoV, i.e., the area of the inspection captured on the camera’s image sensor) and a camera’s optical system although it can be calculated very easily.
This white paper gives several examples to plainly describe how to select a camera lens that satisfies your FoV requirement.
