The CS-150, CS-160, LS-150, and LS-160 are light-measuring devices capable of helping to maintain the quality of a variety of light sources at a high level due to their wider measurement ranges that extend to much higher luminances than those of conventional devices.
3) Luminance is the luminous intensity (brightness of the light source) per unit area of the light and is represented by cd/m2 (candela per sq.
The independent variables included the color and luminance of an image that was reflected on the vehicle's windshield.
Until a few years ago, measuring luminance distributions was prohibitively expensive for most applications, requiring sophisticated equipment and effort.
Figure 13 shows the measurement results of the spatial luminance emitted from the injection-molded LGPs having convex and concave MLAs at the nine different locations indicated in Fig.
The relationship between the luminance and the drive current of each set of LEDs was established, as shown in Fig.
With its intense power and high coupling efficiency, the SolarTec CL effectively illuminates the 3M HL High Luminance Light Fiber in significantly greater lengths than is possible with other systems.
Many customers that we approached heard the term 'photoluminescent' and immediately thought of glow-in-the-dark toys, Halloween-gimmicks, and similar items that only emit a short-term luminance of maybe 30 minutes to an hour.
Once they viewed two sets of varying quality side by side, however, 88 percent preferred the screen with better wide-angle luminance - a brighter, crisper screen at a variety of viewing angles.
5 of the software features even higher quality of color and luminance calibrations and ICC profiles, improved customizable reports, enhanced DDC/CI support, and a number of user interface improvements.
The "Vocabulaire international de reclairage" [CIE 1987] defined glare as the particular condition that could cause discomfort or could reduce visual performance, the visibility and the capability to define details and objects, caused by an unsuitable luminance distribution, or by high luminance contrasts within the visual field.
