***SPECIAL NOTE*** If you want you can also use the extra Velcro and you can attach the bottom filter in place so you can tilt and use your microscope at various angles of tilt if you want.
***SPECIAL Operational Notes**** NEVER USE THE Focus Knob on the Microscope when trying to view the strain pattern in a diamond It is easier to tilt & turn your microscope mounted tweezers You will be wasting time and chasing your tail if you constantly try to refocus your microscope using the focusing knob when looking at and viewing strain within the diamond. Not until you get use to how to find and observe the strain pattern then you can fine turn the focus using the main focusing knob on the microscope especially if you are taking photomicrographs then small adjustments are quick and easy.

***SPECIAL NOTE*** Pre-Focus your microscope so that focus is approximately on the tweezers almost parallel to the work platform. You will also want to first start at low magnification to find the strain pattern then increase power setting to desired strength.
