Our team has built and evaluated a device for multispectral imaging called the multispectral digital colposcope (MDC3). As a regular colposcope, the MDC3 illuminates a 3cm diameter area of the cervix with white light at 3X magnification. Additionally, the MDC3 provides three fluorescence images with UV (350-360 nm), violet (410-430 nm), and blue (450-460 nm) excitation, and two reflectance images with violet and blue illumination (6 images total).\n\n<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1373\" height=\"985\" src=\"http:\/\/biophotonics.bccrc.ca\/wp-content\/uploads\/2016\/01\/cervix-mdc3.jpg\" alt=\"cervix-mdc3\" class=\"wp-image-489\" srcset=\"https:\/\/biophotonics.bccrc.ca\/wp-content\/uploads\/2016\/01\/cervix-mdc3.jpg 1373w, https:\/\/biophotonics.bccrc.ca\/wp-content\/uploads\/2016\/01\/cervix-mdc3-300x215.jpg 300w, https:\/\/biophotonics.bccrc.ca\/wp-content\/uploads\/2016\/01\/cervix-mdc3-768x551.jpg 768w, https:\/\/biophotonics.bccrc.ca\/wp-content\/uploads\/2016\/01\/cervix-mdc3-1024x735.jpg 1024w, https:\/\/biophotonics.bccrc.ca\/wp-content\/uploads\/2016\/01\/cervix-mdc3-418x300.jpg 418w\" sizes=\"auto, (max-width: 1373px) 100vw, 1373px\" \/><\/figure>\n\n\n\n<p>\n\nThe figure&nbsp;shows reflectance and fluorescence imaging of the cervix by the MDC3.
