- | ====== Can I replace the lens on Pixy2? ====== | + | ====== The image in PixyMon is blurry ====== |
- | It depends on which version of Pixy2 you have. Pixy 2.1 has a replaceable M12 lens, but Pixy 2.0 does not. | + | You can focus Pixy 2.1 by turning the lens clockwise or counterclockwise. Do this while looking at the PixyMon window while running the Video program. |
- | You can use practically any M12 lens with Pixy 2.1 as long as it has an IR-cut filter. (The IR-cut filter is something all CMOS sensors need to eliminate most of the ambient IR light, which can adversely affect the color fidelity.) Pixy 2.1 ships with a 1.7mm focal lengh F2.0 lens, which gives it an 80-degree horizontal field of view. | + | Note, if you have a Pixy 2.0, there is no way to adjust the focus, however, it is focused at the factory for the best depth-of-field. |
- | + | Pixy 2.1's lens will focus on objects that are very close, even less than an 1/4 inch from the lens. However, most users prefer to operate Pixy 2.1 with its lens focus set to infinity, which (for Pixy's lens) means that any object that is 1 inch or farther from the lens will be in focus. (note: we set the focus to infinity before shipping each Pixy, although it may shift slightly in transit). | |
- | Pixy 2.0 has a slightly smaller field of view - 60 degrees horizontal. | + | |
