A double-slit interference experimental device for laser pen light source comprises a laser pen, a magnetic ring and a support (with a eye tube) and a double-slit sheet (2 pieces). The laser pen is inserted into the cylinder at the upper end of the bracket; The magnetic ring is glued to the light hole of the laser pointer; The double slit plate is made of iron material and is adsorbed at the end of laser pointer by magnetic ring during the experiment. The invention has the advantages of safety, reliability and low price, and is suitable for group experiment of students. A laser pointer. These days it's very cheap. When I was in primary school, semiconductor laser Pointers suddenly became a fashion luxury for children. At the time, we didn't know what to call this thing that gave off an intense monochromatic glow. The public doesn't know what it's called. I still remember that some experts pointed out in the newspaper that this thing is called a laser pointer, which will cause blindness when it is shot into people's eyes. The Times are developing and society is progressing. Even laser Pointers that light cigarettes can now be bought online.
Portable green laser pointer, applied to outdoor guidance, including: pen body, external part, arranged in the pen body is electrically connected to the light source component and power supply component, the pen body is provided with a rotating bit, the external part and the rotating bit rotary connection; The external connecting part is extended with two external connecting parts, the two external connecting parts are connected to the external; The pen body in turn comprises an ejection part, a receiving part, a fixing part and a tail, and the receiving part is arranged between the ejection part and the fixing part, and the fixing part is connected with the tail; The luminous part of the light source component is oriented towards the outgoing part, and the outgoing part is provided with a heat dissipating device, which is used to conduct heat from the luminous part to the outside; The receiving part is provided with a first accommodating cavity, the light source component is housed in the first accommodating cavity, the tail is provided with a second accommodating cavity, the power supply component is housed in the second accommodating cavity, the exiting part is provided with a light transmitting groove, and the light source component is projected to the outside through the light transmitting groove.
The portable laser pen, through the external part and external parts can make the user can carry portable laser pen at will, through the heat dissipation device set in the outgoing part, effectively improve the heat dissipation of the portable laser pen light emitting part, to solve the problem of portable laser pen near the light emitting part area easy to gather heat; In addition, by opening a chute on the outer wall of the receptacle, the ejector can slide relative to the receptacle, facilitating transportation and storage, thus improving the user experience and making it easy for the user to carry it in his pocket.
To improve the user experience, for example, the pen is shaped like a stick. For example, the body of the pen is long as a whole. In order to facilitate the user to hold the portable laser pointer. For example, there is a buffer layer on the outside of the pen. For example, the buffer layer is made of a soft material. For example, the cushioning layer is made of soft rubber. For example, the buffer layer is set snugly to the outside wall of the pen body. As another example, a buffer layer facing away from the outer surface of the pen body is provided with an anti-slip part. For example, the anti-slip part is a number of ring bumps. For example, the ring bumps are evenly distributed on the skid prevention part. For example, the ring bulge is integrated with the anti-slip part. So, when a user use portable laser pointer, because of the buffer layer is relatively soft, described with the hand grip pen body can get a better grip when feeling, at the same time under the action of antiskid department to improve the user to the friction of the portable laser pen, allowing users in lighter grip as described under the force of a portable laser pointer, and then improve the user experience.
