Open-source Smartphone Adapter in Digital Photomicrography.

Abstract

Background and aim:Smartphones can be used to capture images from the microscope. There are commercial and homemade adapters that can be used to overcome the difficulty of focusing on a smartphone camera. We conducted this study to test if the usage of a homemade adapter reduces the time and effort of the operator in comparison to the free-hand technique in smartphone photomicrography.Materials and Methods:We made a simple smartphone adapter for digital photomicrography. Thirty-two operators first captured the image on the smartphone with the free-hand technique and then with the adapter thrice from a microscope. The time for focusing was compared statistically by paired t-test. A survey was conducted to know operators's opinions on adapter-assisted photomicrography.Result:All the participants were able to capture images from the microscopes. The average time for focusing with adapter was (11.89 ± 4.19 seconds) significantly (P = 0.0001) lower than the free-hand technique (25.56±11.81 seconds). However, the images yielded from both techniques were of equal quality. The majority of the participant found the method to be easy and reduce their effort in focusing and capturing an image.Conclusion:Low-cost homemade smartphone adapter helps in reducing the time required for capturing an image from the microscope. It decreases the effort of the operator in comparison to the free-hand technique. Hence, it may be a good choice for those who need to capture images from the microscopes frequently for either telemedicine or research purpose in resource-limited settings.
