Uniform light source

The spherical illuminators work on the principle of an integrating sphere.

 

The LE6 is a light source that illuminates the interior of a sphere. A unique white diffuse coating covers the inside. A plane (measuring window) usually needs to be small compared to the diameter of the sphere and when oriented perpendicular to the incident light, the plane is illuminated remarkably uniform. Due to our internal design, the measuring window can be much more prominent.

The construction allows you to dim the light down to approx. 1% of the maximum illumination without changing the color temperature, which is 3200 K +/- 50 K. Also, different filters for adjusting the color temperature are available as a 50 W and a 100 W version.

LE6-S is a cheaper, non-dimmable version of LE6-50/100 with a constant illuminance of approx. 3000 lx / LE6-50-S and 8000 lx / LE6-100-S.

The standard test chart size for the illuminators is our D280 format. D240S has the same slide format but a smaller picture format, and it fits without an adapter. Adapters are available for the chart sizes D240 and D205.

For the illuminators LE6 a USB interface is available as an option, which means the light intensity can be measured and controlled by a Windows PC.
