The 5 most important specifications when purchasing a technical white light source:

1. Integration into your setup

You need the light from the white light source in the right place in your optical setup. Free beam light sources are therefore often not the best solution. Things are much easier with a light source for multimode fiber or liquid light guides. The light source can be placed next to your setup. With the light guide, the light reaches every position. With a collimator you can adjust the beam diameter to the required size.

2. The Spectrum (color temperature and CRI)

For technically demanding applications it is often necessary to take a closer look at the spectrum of the white light source. The color temperature provides an initial orientation as to what the spectrum looks like. The lower the color temperature, the further the spectrum is shifted towards red. A second commonly used value is the CRI (Color Rendering Index). It indicates how natural the color reproduction is. A high CRI indicates that the light source’s spectrum has few gaps. The best thing to do is to look at the actual spectrum and make sure that all the wavelengths you need are included at sufficient intensity.

3. Power and Luminance

The strength of a white light source is specified in lumens or watts. Caution is advised when comparing different light sources, as many manufacturers do not specify the usable power at the output, but rather the total power emitted by the lamp. We always tell you the power you can expect at the end of your light guide. For the vast majority of applications, it is not enough to simply specify the light output. Luminance is also important. If a lot of light needs to be focused on a small area, then this is only possible with a high luminance. The smaller the illuminating surface is with the same power and the same beam angle, the greater the luminance. In our white papers High Brightness vs. High Power and Microscopic Spotlight Generation you will find the tools to estimate the necessary luminance for your application. We would be happy to help you with this in an online meeting.

4. Control (software, trigger, speed)

If the light source needs to be precisely synchronized with a camera or other sensors, then trigger inputs and outputs are the method of choice. There are big differences when it comes to speed. What is the maximum frequency that can be used? How short can the pulses generated be? If the light is to be controlled via a PC, a corresponding interface is required. Today this is USB. Our light sources have trigger in and out sockets and a USB interface. The scope of delivery includes a GUI for controling the light source and a software development kit (SDK) for Python and LabView.

5. Lifetime and Quality

The lifetime of a white light source is usually determined by the technology used. White light LEDs have a lifespan of well over 10,000 hours. By definition, the output of the light source is at least 70% at the end of its life. Good cooling and high-quality electronics are the prerequisites for the lamp’s lifetime to be fully utilized.
