Core Microscopy Objectives

Camera: Apple iPhone 12 Pro
Exposure: 1/60
Aperture: f/1.6
Focal Length: 26mm equivalent
ISO: 160

Core microscopy facilities take an absolute beating.  This 20x objective is an air objective and not an oil immersion objective.  Yet it is coated in oil which means users are dragging the objective through oil.  More troubling however, is the scrapes and gouges as the users have dragged the stage across the end of the objective.

This is the same objective that has been cleaned, which reveals scratches in the lens of the objective. <sigh>…
