When choosing a microscope, it’s important that you know your magnification needs. This will depend on your sample, its size and what level of detail you need to see. Afterwards, you can to find a microscope that meets your magnification needs with a simple calculation.

We present two figures of merit based on singular value decomposition, which can be used to assess the noise immunity of a complete Stokes polarimeter. These are used to optimize a polarimeter featuring a rotatable retarder and a fixed polarizer. A retardance of 132° (approximately three-eighths wave) and retarder orientation angles of ±51.7° and ±15.1° are found to be optimal when four measurements are used. Use of this retardance affords a factor-of-1.5 improvement in signal-to-noise ratio over systems employing a quarter-wave plate. A geometric means of visualizing the optimization process is discussed, and the advantages of the use of additional measurements are investigated. No advantage of using retarder orientation angles spaced uniformly through 360° is found over repeated measurements made at the four retarder orientation angles.

In other words, if you need higher magnification levels than what your current setup allows you, it might not be necessary to change microscope. In fact, start out by simply changing the monitor.

How much magnification do you need and which microscope meets those requirements? Here’s a guide on how to answer those questions.

Zero order waveplate

Example 1 – 24’’ monitor: Let’s assume we’re using a PRESTIGE with a +10 lens and a 24’’ monitor. In this case, the width of the monitor is 531 mm, making the minimum field of view 125.1 mm.

For more information on the technical capabilities of each microscope, we refer to the technical specification pages or product manuals.

Note that each lens has different magnification ranges. Which microscope and which lens you should choose depends on your object and what magnification levels you need.

To know the lowest possible magnification capabilities of the microscope then, use the minimum field of view. And vice versa, to know the highest possible magnification capabilities of a digital microscope, divide the monitor width by the maximum field of view on that monitor.

To know the minimum magnification capabilities with this setup, we’ll divide 531 mm with 125.1 mm. This equals approximately 4.2, meaning that the PRESTIGE as a minimum will magnify a sample 4 times on a 24’’ monitor and with a +10 lens.

By changing the monitor to a 27’’ monitor, we’ll change two factors in our equation: Monitor width and field of view. This ultimately changes the maximum magnification capabilities of the PRESTIGE to 145x.
