Range Finding Lasers

What are Range Finding Lasers?

Range finding lasers are the laser source that drives a range finding system.

These lasers are designed, manufactured, and tested to be resistant to harsh environments, with a wide operating temperature range, shock and vibration hardened, and low SWaP (size, weight, and power) characteristics, enabling lightweight, handheld, portable range finding devices.

Typically, range-finding lasers have a wavelength of around 1.5µm to be considered “eye-safe.” The term “eye-safe” is often debated. This term is used because wavelengths around the 1.5µm range are strongly absorbed in the cornea and lens, making it much more difficult to reach and therefore damage the retina. Of course, the wavelength is only part of the equation, as power level and optical intensity are significant factors in the level of safety for any laser. The main takeaway here is that lasers with a wavelength around 1.5µm and with an appropriate power level (e.g., laser sources utilized for range finding devices) pose significantly less risk to the eyes of people in the surrounding area when properly operating the device.

So, what is Laser Range Finding?

Laser range finding is a term used to describe the process of determining the distance to a fixed object.  This process is essentially a simplified version of laser radar, and therefore has many of the same requirements as LIDAR lasers.  Since we are only considering stationary targets and distance is the only thing being measured, range finding lasers are always pulsed to measure the roundtrip time-of-flight and calculate the distance to the target.  An additional constraint on laser range finding that not all lidar systems have is the need to be very careful about eye safety since they are typically operating over shorter distances and in more populated areas.  As a result, most of these lasers operate around 1.5 microns in wavelength, which is considered to be “eye-safe” because of the extremely high-water absorption, useful for protecting the sensitive retina. These lasers are typically OEM versions designed to be easily integrated into your final package or system as a laser rangefinder (commonly misspelled as laser rangfinder) for the military, golf, hunting, shooting, construction, forestry, and many other industries and applications. On this page, you will see a list of all of the range-finding lasers for sale, including both passively and actively q-switched Er: Glass lasers.
