What is the power output of the Mechano Laser Pointer?

All visible light and invisible light (ultraviolet and infrared) that exist in the universe belong to the electromagnetic spectrum. But the visible spectrum (source: NASA) is only a small part of the range that we can see with the naked eye. Such as: green laser pointer grass, blue sky, red apples, purple grapes; think of rainbows or prisms, or even OLED TV screens where all color profiles are visible. Humans can usually see the wavelength range from 380 nanometers to 700 nanometers (NM: nanometers). Scattered light provides you with a more visible beam, which is very suitable for signaling to specific objects in the sky at night. You can of course use other beam colors for astronomy, but green is usually better for visualization purposes. Light energy is an important part of the life cycle of the earth, and it may be the same in many parts of the universe. Sunlight provides energy consumed by photosynthesis for plants, and edible plants full of solar energy for animals. We see the rising and setting of the sun and the moon every day, and the stars at night leading to the sky. Light protects us from danger and predators.
