The holographic photos we mentioned earlier use small particles to change the parallel light reference beam to spherical waves; such a holographic photo is a special concave lens. A similar method can be used to produce convex lens, cylindrical lens, and other optical elements. This kind of component is as thin and light as paper, and will not be broken.

. Ultraviolet rays and infrared rays have the opposite characteristics in these directions. The ultraviolet rays have short wavelength, poor diffraction effect, strong penetration ability, low thermal effect, and obvious chemical effect. Therefore, UV disinfection is usually used instead of heating.Color Sunglasses: mainly rely on the absorption of light to reduce the intensity of sunlight. Add different colored compounds to the glass to make sunglasses of different colors, and they absorb diffe

belongs to the ordinary level, while the latter belongs to the ultra wide angle, and the degree of comfort varies greatly. 3. Lens Coating The purpose of lens coating is to reduce the reflection of lenses and increase the light transmittance. If the lens has obvious reflection, the light transmittance of the lens is not very high. The telescope I bought a few years ago has a red coating, indicating that the lens of the objective lens has a lot of re

, connections can be realized. This is especially suitable for point-to-point connections within short distances, at the same time, the power consumption is also lower. However, its disadvantage lies in its distance, which requires about 4 cm contact to achieve transmission, while Bluetooth can now achieve a connection distance of 100 meters. Currently, NFC is usually used as a "bridge operator". Android devices often use NFC as a Bluetooth verification method, removing the hassle of pairing and
