Make A Binocular Collimator

The 10x eyepieces are the most common in the ocular industry.


When you look through binoculars, you can see things, such as test samples, through a magnified lens. This magnification brings objects close up so that you may inspect and examine them clearly. However, if binoculars have poor collimation, you will notice that the vision you see is fuzzy or not sharp. To improve the clearness, you must enhance the collimation. This will help scientists and students see objects with more clarity.


Instructions


1. Untwist the two eyepieces from the head of the binoculars. You may need to unscrew the eyepieces to get them loose. This expose the eyepiece tubes. Set the eyepieces side by side on a flat working surface, making sure to not confuse the left with the right.


2. Adjust the eyepiece tubes so that they are equal in height. Use the lever or rotating device on the binoculars to move the tubes up or down.


3. Fit the 10x eyepiece into the left eyepiece tube. Keep the cross-line graticule facing up. A cross-line graticule is used for the alignment of images when it is adjusted and provides sight for an overall view, too.


4. Put the Centring slide on top of the stage or platform where the test slides go. Look through the left eyepiece 10x lens and rotate the vision lens until the cross-lines are in focus.


5. Adjust the binocular stage to bring the Centring slide closer to the bottom lens until they are nearly touching. Bring it back into focus.


6. Leave the adjustment settings on the left eyepiece tube and switch the 10x eyepiece to the right eyepiece tube. Repeat the same adjustments so that you look through the eyepiece tube with the 10x lens and see the Centring cross-lines in focus. This means that you have successfully collimated the binoculars.
