We use only darkfield and brightfield as it allows for all the anomalies to be seen. Phase contrast is not used in our microscopes and training as it doesn’t allow for any other anomalies to be detected and is used mainly to avoid the cost of a professional darkfield system. We can add a phase contrast kit as an optional extra on our microscopes if it’s something a practitioner needs. However, in terms of what can be seen in the different techniques, the best combination is brightfield and a good quality oil-immersion darkfield system.
