Therefore, the Bluetooth laser measure has been better used in many fields. Essentially, the laser beam can reach the most distant or inaccessible points and disposes of the utilization of hazardous structures, along with the consequent hazard measurement action in height on balconies or rooftops.Д¬an It Replace the Traditional Folding Rule or Tape Measure?Д¬ompared with a traditional folding rule or tape measure, Bluetooth laser measure is faster and more accurate. The second reason for its popularity may be the worker's safety. Bluetooth laser measure helps you achieve accurate and fast measurement. Instead of old boring tape or wheel, you take a nice-looking Bluetooth laser measure with color LCD out of your pocket and do your job immediately without the need for another colleague. We feel the best reason behind its popularity is that it is practical and easy to carry. For example, you may use its camera to save important data in its memory and realize accurate point-to-point remote measurement. Considering that, Mileseey p7ak is a marvelous laser device that measures distances and performs many other jobs. However, this operation is time-consuming and inefficient. It is very warmly welcomed by the masons and constructors who always had a folding rule, measuring tape, or wheel in their hands, and another person is engaged to hold the other end of the tool. It is possible to make more accurate measurements of the width of the hair by measuring each of the вЂњmaximaвЂќ in the pattern and then averaging the resulting values.Bluetooth laser measure is the product of modern technology used to measure short-to-long distances up to 200 meters.

Hair width = (0.000000680 m * 2 m) / (0.0175 m * 1/2)ДЄnd the final result is 0.000155 m or 15.5 Вµm.ДЄccording to The Physics Factbook, human hair ranges from from 17 to 181 Вµm which would suggest that my measured value is low but not unreasonable. There is no label on my pointer so I will use 655mn for my wavelength. For example red laser pointers have a typical range between 630 nm вЂ“ 680 nm. If there is no label then you can use typical values. Hair width = (Laser Wavelength * distance to wall) / (width of center pattern * 1/2)ДЇor the Laser Wavelength look at the label on the side of the laser pointer. Now for a little math! HereвЂ™s the equation: My laser pointer has a button that you have to keep pressed so I used a wooden cloths pen.

YouвЂ™ll also need to figure out how to keep the laser pointer turned on without touching it.

build a stand from Legos, Erector Set, Lincoln Logs, or similar.

I used some spare aluminum channel to make a stand. There are lots of ways to secure the laser pointer.

We need to mount or secure the laser pointer so that it is level and steady. We can then measure вЂњwвЂќ and solve the above equation for вЂњdвЂќ to find the width of the hair. If we replace the double slit with a strand of hair then light waves will wrap around the hair and interfere in the same way as the double slit setup. вЂњdвЂќ is the distance between the slits (mm).вЂњО»вЂќ is the wavelength of the laser (Ојm).вЂњzвЂќ is the distance from laser to target (m).The spacing of the fringes is controlled by the wavelength of the light source, the distance between the slits and the distance between the laser and the target by the formula: w = zО»/d
