The name "laser microscope projector" sounds scary, but it's actually a very simple device.
The main component is a laser pointer, which is the laser pointer used by the teacher for lectures, which can emit a bright red light spot. Some are sold as toys, and it seems that the price does not exceed 10 yuan. As shown in the figure above, use a clip to clamp the laser pointer, straighten the paper clip, and bend a ring with a diameter of 3 or 4 mm in front to clamp the laser pointer together.
When the clip clamps the switch of the laser pointer, it emits a beam of red laser light, adjust the state of the paper clip, and let the laser light pass through the ring.
Drop a drop of water on the ring, because the drop is approximately spherical, equivalent to a convex lens. After the laser beam passes through the water drop, it will be diverged by the water drop, leaving a large red spot on the wall.
You will find many shadows in the light spot. what is that? These are small particles in the water that are invisible to the naked eye. There are these tiny particles in the water droplets. Because of the limited resolution of human eyes, we usually can't see them.
But when the laser passes through these small particles, a part of the light will be blocked, forming a shadow. Properly adjust the distance between the laser pointer and the water drop and the distance between the water drop and the wall to form a large spot on the wall. Assuming that after being refracted by water droplets, the spot area projected on the wall is 1000 times that of the original laser pointer, then it is equivalent to magnifying these shadows by 1000 times, and we can easily see the small things in the water—— To be precise, it is their shadow.
We call this device a "laser microscope projector" because: first, it can create a projection, and second, it can play a role in microscopic magnification.
The following is a more sophisticated projector of this kind made by a foreign friend.
The laser is placed horizontally and the syringe is placed vertically. The needle tube is filled with water. Through the plunger of the syringe, the size of the water droplets at the needle can be adjusted arbitrarily, and the needle tube itself can also move up and down.
He uses a green laser, which can project a very clear enlarged projection in a dark environment.
Electronic Lock Motor product introduction:
Electronic Lock Motor, also known as Intelligent lock motor, Belong to small reducer series, the main structure composed of drive motor (motor) with a reduction gear box, composed of a shaft connection, form integrated motor reducer; Drive motor is purchasing product, reduction gear box is customized according to the project product demand, the maximum power under 10 w, maximum voltage up to 12 v, below 25 mm diameter size.
Functions: it is widely used in various intelligent locks, such as Shared bicycle lock, fingerprint lock, glass lock, safe lock, hotel lock, family lock, inductive smart lock, etc
Features:China Electronic Lock Motor is based on micro precision reducer development, small intelligent micro precision reducer can do 10 mm in diameter, is widely used in safe, locks, smart locks, sensor intelligent lock;
This kind of motor has the characteristics of low noise, low energy consumption, small volume, light quality, high precision, large torque and durability
Method of use: the best stable in horizontal plane, installed on the China Electronic Lock Motor output shaft parts, cannot use a hammer to knock, knock prone to press into the dc Electronic Lock Motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
Electronic Lock Motor should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a electronic Lock Motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
China Electronic Lock Motor should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
The longevity of Electronic Lock Motor is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.
â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
when it come to volume production,we're a major player as well .each month,we rurn out 600000 units,all of which are compliant with the rohs directive.Have any questions or special needed, please contact us, we have the engineer group and best sales department to service to you
