Using a powerful laser pointer placed on the chainring, you can check the alignment of the chain. If this is correct, your rear wheel is also in the correct position. Laser pointers do not guarantee that the housing is parallel to the laser beam. There are additional lasers for adjusting the chain, with a precise plane that guarantees that the laser beam is also parallel to the plane. That's why I had the high power laser pointer sight back at the time, there was always a slight deviation after turning the chainring, so this part was unnecessary for me. I actually put a straight edge on and I think it's pretty straight. But I think the laser makes things easier. For effective sintering, you can use a strong, wide laser pointer to sinter the filling of the object. For "skin" you can lower the focus and power of the laser in order to reproduce the smallest details.
Clearly visible laser pointer
A bridge over the highway let me down the other day, a very bad fashion and money making business. But that's going to pass quickly, isn't it a red laser pointer? I'm curious to know if a green laser pointer with a clearly visible beam can trigger the light barrier, or if the wavelengths used have to be similar to trigger the beam aimed at the sensor or its scan area to the reflector. According to the wishes of the state of Baden-Württemberg, the sale of dangerous laser pointers to ordinary consumers should no longer be permitted. State parliaments should call on the federal government to ban the sale of laser pointers with power over 1 milliwatt (mw) and work towards a Europe-wide ban at EU level. No insurance will be provided in the event of an accident or liability caused by the green laser sight. Whether self-harm or damage to third parties, the laser can in principle be used as an aiming aid for the weapon; there is also a telescopic viewfinder.
So far in Germany, the Federal Institute for Occupational Safety and Health (BAuA) has only had a non-binding product description, which does not allow state labour inspectorates to intervene, according to the application the state intends to submit. Heading to the Bundesrat in the next few weeks. The luminous intensity of EU imports tends to be much higher than specified by the manufacturer. Temporary glare from laser pointers can cause afterimages or so-called "flash blindness". This can be a factor that compromises flight safety, especially during the landing phase of an approach. Absolute glare occurs when the eye cannot adequately adapt to the lower brightness of the rest of the field of view due to interfering light sources.
