Eliminate reflections and shadows during inspections

Working conditions vary. Perhaps you’re sitting in a dark room with your digital microscope and need a light source to properly see your sample. But the light source can also cause reflections and shadows that interfere with quality control. Luckily, it’s quite simple to remove these distractions. Here is how.

Eliminate reflections

If you’re working with a reflective surface or an object that is covered in liquid residue, an added light source to your digital microscope might causes reflections. Let’s say you’re working with a PCB. The light source can cause reflections on smooth surfaces of the board, interfering with the image quality. In this case, a polarizer set will filter out the light causing reflections, allowing the digital microscope to create a much crisper image to work with and store for documentation purposes.

Another application for the polarizer set is if you’re working with seeds. More specifically seeds that have been covered in a liquid. Using a polarizer set will eliminate reflections created by the the liquid still covering the seeds.

Avoid shadows 

Adding an overhead light source can also cause shadows on your working area, making it difficult to see the outline of a sample properly. To eliminate shadows, place the sample on a glass table. The glass table will make it much easier for you to see the outline of your sample and create great documentation material with the digital microscope for customers and supply chain partners.

One final tip before you go

If you’ve already added a white ring light to your digital microscope, but the light isn’t focused where you need it, or maybe the point light is too sharp, then try a fresnel lens or diffusor.
