The colposcope is a low-powered microscope with built-in illumination which can be used for a close examination of the cervix and vagina, enlarging the area 10-20 times. With this instrument, cervical areas of dysplasia, carcinoma in situ and early invasive cancer are usually visible. As a result the colposcope can be used to direct the actual site for cervical biopsy with great accuracy. The colposcope is also useful in visualizing the vaginal vault to study the possibility of neoplastic changes both before and after surgical treatment for carcinoma of the cervix.
阴道镜是一种带有内置照明的低倍显微镜，可用于仔细检查宫颈和阴道，将区域放大 10-20 倍。通过这种仪器，通常可以看到宫颈区域的发育不良、原位癌和早期浸润性癌。因此，阴道镜可以非常准确地指导进行宫颈活检的实际部位。阴道镜也可用于观察阴道穹窿，以研究宫颈癌手术前后阴道发生肿瘤性变化的可能性。
