Gauge runs the rule over magnified

Prior Scientific has produced a flexible ruler which can be used to quickly and easily assess the total magnification of any system displaying an image on a screen.
When inspecting fibre terminations using a video microscope it is not always easy to determine the exact magnification being used It is easy for the user to labour under the misconception that the magnification is 200x or 400x

Software simplifies image acquisition
Acquiring images onto a computer from an analogue source such as a CCD camera has always been a fairly complicated process.
With an optical microscope, calculating magnification is easy, simply by multiplying the magnifications of the objective lens and eyepiece.
The complication of using a video-based system is that the overall magnification depends not only on the optical elements but also the size of the CCD sensor and the screen.
So the problem is how to determine the magnification of a video fibre microscope.
Prior Scientific has produced a flexible ruler which can be used to quickly and easily assess the total magnification of any system displaying an image on a screen.
It is calibrated for use with a 125um fibre.
To use the ruler is as easy as aligning a reference mark with the left-hand edge of the fibre and reading off the magnification figure where the right hand edge crosses the scale.
