Can mineral oil be used place of immersion oil?

Mineral oil can be used as a substitute for immersion oil in some cases, as both provide similar refractive indices that can enhance the clarity of microscopic images. However, immersion oil is specifically formulated for microscopy, offering better optical properties and reducing the risk of damage to the microscope lens. Using mineral oil may not provide the same level of performance and could potentially lead to issues with lens clarity or longevity. It's best to use immersion oil designed for microscopy whenever possible.
