Trimble SX12 Laser Pointer White Paper 4 Laser Pointer Modes to Maximize Visibility in Different Conditions To adapt to different lighting conditions, target type, and working range, there are three different modes available for the laser pointer. Tap and hold on the laser pointer icon in the instrument functions screen of Trimble Access to change the laser pointer mode. Laser Pointer Mode Brightness and Corresponding Solid/Flash Pattern Low-lightmode ● Meant for use in low-light conditions, such as tunnels ● The laser is always on, but the intensity is lowered to make it easy to pick the center of the point Standard mode ● Meant for use in most lighting conditions ● The laser is always on, and the laser intensity is maximized within the Laser Class 1 categorization of the laser. ● This mode is useful for most lighting conditions and surface types Extended Range Flashing mode ● Meant for use in bright conditions, on dark surfaces or when working at an extended range. ● The increased peak intensity helps you see the laser at longer ranges. There is a constant blink pattern to maintain the Laser Class 1, eye safe classification. Separate Collimation Correction for EDM and Laser Spot For the SX12 to achieve the unique properties of a green focusable laser spot, with a market leading EDM spot size, and a scan rate of 26.6 kHz, the EDM and laser spot come from different sources. During the production process, the two lasers are calibrated to exit the total station on the same axis (co-axial). The complexity with this system is that temperature changes inside of the instrument result in very small movements in the mechanical structure and optics inside of the instrument, meaning temperature and measurement distance can affect where the EDM and laser pointer are positioned relative to one another.
