Depending on the size and shape of an object, a white ring light attached to a TAGARNO digital microscope might not enable you to see all the details you want.
The primary purpose of using a ring light with your digital microscope is to see your sample better.
However, sometimes you need additional accessories to see the sample properly. Examples include the not hitting the entire object or the light needing to be focused at the center of the field of view. Here is how to solve this.
Fresnel lens
When using a white ring light on a digital microscope, adding a fresnel lens wil ensure that the light is focused at the centre of the field of view. This can be useful if you only need a relatively small area of an object illuminated.
The fresnel lens comes in 3 sizes (50 mm, 100 mm and 200 mm) depending on the lens you’re using it with.
Diffusor filter
At the other end of the spectrum, you might experience that the ring light is overexposing the image on your digital microscope. An optical difussor filter can then be used to get a homogenous illumination of surfaces.
The diffusor filter available through TAGARNO can be used for working distances from 150 mm.
