| *1 When installing the macro lens (CA-LMxx) to the line scan camera, make sure to secure the lens unit with the dedicated mounting stand (OP-87337, sold separately) or an equivalent mount. *2 WD indicates a working distance at reference magnification. WD will vary depending on magnification adjustment. *3 The smallest resolvable feature that can be detected using 550 nm wavelength light. *4 Depth of field applies to an F-stop of 16 and will vary depending on F-stop setting. The indicated depth of field is a theoretical value that assumes 1/2" CCD size and a horizontal resolution of 320 lines. (Circle of least confusion is 40 µm in the image) |
