Can I use an infinity-corrected objective in my microscope to get a longer working distance?

Only if your microscope is designed to work with an infinity-corrected objective. Due to the design of the infinity-corrected objective (see above question), they will not work in a DIN or JIS standard microscope. An infinity-corrected objective on a DIN or JIS standard microscope will not focus. Please also note that the threading for our infinity-corrected objectives is not a DIN standard threading and the objectives are physically not interchangeable with DIN or JIS objectives.
