- Lightweight and portable
Light weight, compact and battery powered, the LS-150/160 weighs just 850 g (not including batteries). These ergonomic and portable instruments include a hard case as standard meaning they are easy to transport and operate for prolonged periods.
- SLR (single-lens-reflex) optical system
The LS-150/160 single-lens-reflex design ensures that there is no difference between area indicated in the viewfinder and the actual measurement area. The easy to use SLR optical system has been designed to be practically flare free which eliminates the effect of illumination outside the measurement area, ensuring accuracy.
- Spot measurement for small target areas
The 1° acceptance angle of the LS-150 can measure areas with a diameter as small as 14.4 mm (at a distance of 1,014 mm); using the optional close-up lens, this can be reduced down to measurement diameters as small as 1.3 mm (at a distance of 205 mm).
The 1/3° acceptance angle of the LS-160 can measure areas with a diameter as small as 0.4 mm (with close-up lens 110 attached).
- Large monochrome LCD Display with backlight
Measurement data is shown both inside the viewfinder and on the external display, supporting different modes of user operation.
- Data memory for 1000 measurements
- USB 2.0 communication
Connect with a PC via USB 2.0 to send measurement data and receive control signals. The instrument can also be powered by USB cable, ideal for use in measuring rigs or when working with a PC/tablet computer. Data-management software CS-S20w is included as a standard accessory.
- 10 Calibration channels available for calibration to a user reference lightsource
The LS-150/160 can be calibrated to a user reference light source; this can be used to further reduce errors when using multiple devices.
- Luminance, luminance difference, ratio, peak and valley measurement
Based on the particular application, measurement values can be set to instantaneous luminance, peak/ valley luminance and luminance ratio.
Besides the measurement of absolute values, the instrument can also display values relative to a defined standard (target). That way differences in brightness of large surfaces or similar items can be quickly ascertained.
Areas of application
Practically anything that illuminates or reflects light can be measured with Konica Minolta's portable luminance meters. For example: signal lights, traffic lights, road surfaces, tunnel walls, airport lighting, lamps, LED's, picture tubes, etc.
Users could use the LS-150/160 to guarantee minimum brightness, exchange lamps that are fading before any quality or safety issues occur, or build quality assurance into the production of lamps. You can also check indirectly illuminated objects including projection screens, effect and display lighting. The size and portability of this instrument allows you to operate in any location where a measurement is needed.
