Frequently asked questions

The range finder algorithm is a closed loop controlled circuit. This means that the LRF dynamically adapts its behaviour based on the environment, the target distance, target albedo etc. A lower range performance when integrated into a host system typically occurs when the range finder experiences optical crosstalk within a system. This happens if energy from the transmitter channel is directly coupled to the receiver. This causes the LRF to reduce the emitted energy in order to protect the receiver from being destroyed; and the result is a reduced range performance.

Yes, we provide a so-called interface kit, so that you can put the LRF module into operation within 10 minutes of receiving the goods. This way you get a better feeling of how the module works and what you can achieve with it.

Yes, it is possible to use pointer (830 nm) and measuring laser (1550 nm) simultaneously. The module will keep its original eye-safety level, as the two wavelengths are independent for the laser classification.

The housing of our LRFs is not sealed and the module itself is not gas or water-tight. In case, the host system is flushed with a gas (e.g. nitrogen), our modules provide ventilation openings to deal with this.

When the laser rangefinder is activated, a series of extremely short laser pulses from the transmitter are sent through the smaller objective lens to the target (multi-pulses). At the target, laser pulses are reflected back. Most of the pulses are absorbed or diffusely reflected by the target and only a very small percentage are reflected back to the LRF Module. These remaining pulses are received by the larger objective lens and are focussed onto the proprietary receiver diode. The receiver diode starts sampling the echo at a very high frequency and together with our sophisticated measuring algorithms it allows the Laser Range Finder Module to calculate a reliable distance – even if only a few pulses were reflected.

Vectronix is one of the few truly integrated Fiber Laser Manufacturing companies on the world. We have two different versions of Fiber Lasers (LRF 6019 & LRF 7047) and they are all fully developed and produced here in Heerbrugg, Switzerland. We developed our own transmitter electronics as well as the matching receiver electronics to get the optimal performance out of our Laser Range Finder Module. 

When integrating or handling a module, be careful with ESD as the LRF module is sensitive to electrostatic discharge. Do not touch any electronics or components unless protective measures are in place. Measures such as wearing a grounded wrist strap, use of anti-static bags and trays, and a workplace with grounded mats.

Yes, it is possible to mount and operate our Fiber Laser Modules (LRF 6019, LRF 7047) with the Laserbox detached, to minimize the front area. To do this, a special mounting set is required. This set contains a Flexcable, a Flexcable Securing Clip and Mounting Screws with washers.

The Laser Rangefinder modules LRF 6019 and LRF 7047 are equipped with a 1550 nm laser for distance measurement and with an optional 830 nm laser pointer. The pointer is built directly into the laser measuring system and uses the same fiber and optics as the 1550 nm laser. If this option is chosen, the boresighting of the complete LRF module can be done easily by just aligning the 830 nm pointer, as this aligns automatically also the 1550 nm laser, which is responsible for the distance measuring.

To make the laser spot of the 830 nm laser pointer visible, a standard NIR camera or a night vision device can be used. These devices are significantly cheaper than a 1550 nm camera. By using a boresight chart at a defined distance, the LRF can be aligned by bringing the main optical axis of the host system and the LRF to the predefined positions on the boresight chart.
