When it comes to gauging distance between an observer and a target, lasers have achieved a top spot. Used across a wide range of industries from forestry to surveying, and industrial manufacturing, laser rangefinders are considered as the most reliable tools.
Read ahead to enhance your understanding of laser rangefinders, manufacturing, and choice for an intended application.
Manufacturing of rangefinders
Top rangefinder manufacturers use advanced optical, electronic, and mechanical engineering to design and develop devices that ensure accuracy, durability, and reliability.
Optical system
Optical system is at the core of any rangefinder. It involves lenses and prisms to optimize clarity and light transmissions. Accurate optical alignment is also essential to ensure accuracy and image clarity.
Sensing technology
Modern laser rangefinders use time-of-flight or phase detection method for measuring distances. The devices gauge the time taken for a laser pulse to reflect back from the target. Most common in outdoor and long-distance models.
Ultrasonic rangefinders use sound waves for the purpose, triangulation method is used in rangefinders for short-range, indoor use.
Electronic processing happens through built-in microprocessors that interpret signals and calculate distance:
Whatever the purpose, rangefinders are designed to be rugged and ergonomic, and their performance is evaluated through repeated calibration.
Choosing a rangefinder depends on how you plan to use it. Here are key factors to consider:
There are certain factors to consider:
- Use
- Range and accuracy
- Environmental suitability (indoor or outdoor)
- Power and battery life
- Display and user interface
From the discussion, it is evident that rangefinders for indoor and outdoor applications are completely different.So, the intended purpose matters while making the right selection.
