Why should you never look at a wet mount slide with a oil immersion lens?
Wet mounts are not attached to the slide, it is "floating". If you use an oil immersion lens, you have to put a drop of oil on the slide cover so the light can correctly focus. The oil will cause the slide cover to stick to the end of your Oil immersion lens. When you focus the field of focus will stay the same since the slip cover is stuck to the lens. When you go to change objectives, the cover will travel with your oil immersion lense.
