People often ask, what does handheld laser pointers in rangefinders do?
Let’s find out!
What Does Handheld Laser Pointers in Rangefinders Do?
The handheld laser pointers are those with a rangefinder. These devices allow you to aim at any object in front of the projector and then adjust the distance between the projector and the target until it appears sharp on the screen.
This process is called “rangefinding” because the device measures the distance from the projector to the target using a reflected light beam.
How Does a Laser Rangefinder Work?
A rangefinding device emits an electromagnetic pulse in a light wave through its optical system. The light wave is then reflected off the object and returned back to the range finding device. The range-finding device processes the light wave to determine the distance between itself and the object.
The device uses an algorithm to measure distance using the time difference between the emission and reflection of an electromagnetic (EM) signal. This method of measuring distance is used in some types of laser rangefinders.
So, what measurement methods do rangefinders use?
Laser-rangefinder systems use either direct measurement methods (such as measuring the time between sending out a pulse and receiving its return) or indirect measurement methods (such as using an interferometer).
It’s definitely the most accurate way to measure distances, but laser rangefinders are expensive, so they’re not always reliable out in the wild.
How accurate do laser rangefinders take measurements?
Lasers allow you to take accurate measurements both inside and outside with 1mm per kilometer accuracy. Professional construction lasers can be used for measuring distances of up to approximately 150 meters.
Long-distance (1500m) laser devices are mainly used for hunting, farming, forestry, and road building.
What Are the Benefits of Using Laser Rangefinders?
Laser rangefinder devices are the most accurate measurement instruments available today. They’re also useful because they allow for single operator use.
Measure Distances Accurately
Using a handheld optical range finder allows you to measure distances quickly and accurately without having to use multiple workers.
Lasers are less susceptible than traditional tools to measurement error due to incorrect placement of the tool and other human errors. Most professional lasers are equipped with electronic aids for accurate measurement, automatic calibration functions, and allow measurements using the Pythagorean equation (or the “Painters” mode).
Advanced Features
Laser rangefinder technology has improved significantly since its introduction. It now includes advanced features such as measuring distance continuously, delaying measurement times, measuring the sum or difference of two surfaces, and measuring volumes.

Frequently Asked Questions (FAQs)
What is a laser?
Lasers are devices that amplify light using stimulated emission of radiation (SERS). A basic type of SERS uses a closed tube containing a pair of reflecting surfaces and a gas or liquid that is pumped through the tube to excite the atoms of the gas or liquid into emitting photons.
Why are lasers uniquely hazardous?
Laser light has two characteristics that cause it to be hazardous:
- Lasers emit beams of light that don’t expand outwards when they travel away from their source. This makes them safe even if you’re standing right next to the beam.
- The eye can focus light into an extremely tiny point on its retinal surface, which can cause a burning sensation or blindness.
Are all lasers legal for consumer use?
Yes. Some lasers are strictly meant for professional use and should only be used under supervision by someone who has been trained properly.
The FDA requires manufacturers to include warnings about the dangers of using lasers and to certify that their lasers comply with federal safety standards. Most consumer lasers fall into categories I, II, and IIIA; lasers used by professionals may be classified as either IIIB or IV.
What do the different classifications of lasers mean?
The FDA recognizes four major hazards (I to IV) for lasers, which include three subcategories (IIa, IIIA, and IIIB). The higher the category, the more dangerous the laser and the greater the risk of injury if used incorrectly.
Classifications for electrical equipment must be accompanied by a warning label stating the type of device (Classification) and its maximum permissible operating voltage (Approximate IEC equivalent).
Class I laser products are considered non-hazardous. However, they may be hazardous if used improperly. Class II lasers are considered hazardous even when not used improperly.
If you look directly into the laser light, you could get temporarily blinded by the laser light.
When viewing X-rays using an optical aid (such as a magnifying glass), there is increased risk of radiation burns and/or damage to the eyes.
Are laser pointers safe?
Properly used, lasers are safe for most people. However, lasers can cause serious injury if not handled correctly. They can damage the retina of the eyes, which can lead to blindness. Lasers can also burn holes through clothing and skin.
Furthermore, the startling effect of shining a bright beam of lights onto someone driving a vehicle or operating machinery can result in serious accidents.
The FDA is worried about the increase in the number of lasers available for use by consumers. Green, blue and purple lasers are especially worrisome because they’re often used without proper training.
While there are legitimate ways to use laser pointer devices, they may be modified into dangerous weapons if misused.
