Determining true optical quality can be tricky. Many
manufactures will make great claims concerning their optics quality.
When researching optical quality of binoculars you should consider that
you get what you pay for.
Don't be mislead, binoculars with large objective lenses can have poor
light-gathering capability if the optics are low quality.
Here is a simple way to test the quality of the optics:
- Hold the binoculars at arm's length.
- Point them in the direction of a bright
- The circle of light that you see in the
eyepiece is called the exit pupil.
If the exit pupil is clear and bright with a sharp edge then the
binoculars have high quality optics. If the exit pupil is dull or only
bright in the center then the quality of the optics is low.
You should try to choose binoculars that have fully coated
The optics of good quality binoculars will be coated on
both sides with non-reflective film. The coating will deliver more
light to the eyepiece by reducing reflection.
