Optronik Line DSP 200
-
Instrument Systems Optische Messtechnik GmbH
DSP 200 offers outstanding sensitivity and stability for precise measurements even at very low illumination levels. The instrument meets, of course, all requirements of the newest standards, like EN 13032-1 and DIN 5032-7 (2017). A low-noise photo diode with V(lambda)-filtering and optimized electronics provides for a broad dynamic range from 0.1 mlx to 200 klx. At the same time the very high local resolution allows an accurate determination even of high gradients when measuring headlamps. Therefore, the DSP 200 is suitable for all automotive and traffic applications, as well as for flashlights and for measurements of all pulse width modulated light sources.

Luminance Colorimeter
XYL-VI
-
The XYL-VI Luminance Photoelectric Colorimeter changes the traditional structure thoroughly, employs the digital X(λ), Y(λ), Z(λ) sensors to replace the traditional analogue sensors, employs the digital signal measurement system to replace the traditional analogue measurement system. The instrument has no analogue unit, thus it is very simple to overcome the zero drift that is impossible to be avoided in traditional colorimeter. The digital sensor has a large dynamic range. Moreover, it possesses strong anti-interference ability and it has high accuracy. The XYL-VI Luminance Colorimeter contains internal RS232 computer interface. The calibration is done by software. It is suitable for monitoring and remote applications. The XYL-VI Luminance Colorimeter can be calibrated by XYL-VI Luminance Colorimeter software to sample the data and print out the results. It can also be corrected by other standard light sources to obtain very high measuring accuracy of x, y color coordinates and color temperature. It is a real-time measuring system and run under Windows2000/XP.

Konica Minolta Sensing Americas, Inc
Luminance meters are single element detectors that measure photometric brightness. The Konica Minolta luminance meter measures the amount of emitted or reflected light from a surface. These instruments display luminance in either cd/m2 or foot-lambert (ft-L) and they are lightweight, compact and portable. They can be connected to a PC which can store the measurement data and control the device. The LS-160 has a single lens reflex optical system to precisely measure very small (0.4mm) diameters at very short distances, making it extremely easy to use.
