Is it legal for laser pointers to be banned?
This is a common question asked by many people. If you search on the Internet, you will find a lot of wrong information. The term you use to describe a powerful laser pointer has many problems, which automatically makes it legal or illegal. Technically speaking, I understand the peculiarities of the FDA. The term "pointer" directly implies that you aim the laser at something, and if your laser pointer is particularly powerful, you don't want to do this. If you pass less light, you will get a longer exposure time, which will give you more time to paint with the hot laser pointer. The smaller aperture also allows for sharper and wider focus. The exposure time depends on the duration of the painting. Most cameras can take up to 30 seconds of exposure. Therefore, once you set the aperture to a smaller setting (f22, f18), start adjusting the exposure until it is correct.

Well, so many people think that the reason high powered laser pointers are banned is that if they have a certain power, it is illegal to sell them as laser pointers. To be marked as a laser pointer, the laser must be less than 5 milliwatts (mW). However, as long as it meets FDA standards, it is not illegal to have a laser pointer over 5mW. Ideally, you need a small opening and a long exposure. The smaller the opening, the less light passes through. In addition to aperture and exposure, you also need to ensure that the ISO is low, preferably 100. The lower the ISO, the sharper the image. If the laser exceeds 5mW, it can no longer be marked as a pointer, and it is illegal to mark it as a pointer.
