WebMeasure the scale bar image (beside drawing) in mm. Convert to µm (multiply by 1000). Magnification = scale bar image divided by actual scale bar length (written on the scale bar). WebTo fit a contact lens to a patient's eye, a keratometer can be used to measure the curvature of the cornea—the front surface of the eye. This instrument places an illuminated object of known size at a known distance p from the cornea, which then reflects some light from the object, forming an image of it. The magnification M of the image is measured by using a …

Monica Rainey, Optical Engineer, demonstrates and explains how to calculate magnification with a simple setup and …
WebA Barlow lens is nothing but a lens that can be attached with your Eyepiece. It generally multiplies the magnification power of an eyepiece. For example, a 2x Barlow lens will double the Magnification of an eyepiece. If an eyepiece has a 10mm focal length, by attaching a barlow lens, it will turn into a 5mm focal length.
