The modern comparison microscope is a thing of beauty, and for a good reason. Depending on the comparison microscope you use, you can make side-by-side comparisons or compare a section to a whole slide. They’re perfect for seeing subtle differences between samples and making a diagnosis. They’re also great for topical examinations.
The microscope itself will cost you around $500 to $1000. On top of that, you’ll likely need some basic accessories to get started. The most important of these is a light source, but you’ll need a cover for your sample and perhaps even your microscope. Altogether, these accessories will cost you around $800.
Keep in mind that even though some of these accessories are optional, they’re still very necessary. You won’t get very far concerning your education or medicine if you can’t see things up close (and this goes for both physicians and pharmacists).
Essential Features of a Modern Comparison Microscope:
1) The most expensive type of transmission microscope – a comparison microscope – has two sets of lenses, each set with its own tube lens and diaphragm/iris combination. The difference in magnification between these sets is adjusted by a lever which moves an intermediate lens between them.
2) You need a pair of objectives to have a comparison microscope. This means two objectives inside the body of the microscope.
3) A simple transmission microscope uses only one objective lens and has a fixed distance between the eye and the specimen. A simple transmission microscope uses only one objective lens and has a fixed distance between the eye and the specimen. By contrast, a comparison microscope is essentially a compound light microscope with an additional objective lens for each slide to be viewed. This makes comparison microscopes slightly more complex than standard transmission microscopes because you need two objectives for each slide – and these objectives must be aligned within fractions of a millimeter of each other.
4) The last feature of any modern comparison microscope is that it can focus on two different specimens at the same focal plane. The x-y table must also position two slides in optical alignment to ensure that they can both be focused within the same range.
There are some other features to look for when you’re purchasing a comparison microscope. This will ensure that you’ll get the most out of your purchase in the long term.
Variety of Magnification Levels:
The magnification levels on your microscope are important because they dictate how you’ll use it. For example, if you’ve already decided to make slides, 10x magnification will be more than enough. If you’re planning to look at skin samples and need to look at them up close, then there’s no substitute for 40x magnification. Suppose you ever plan on using your comparison microscope as a microscope and not just as a top-viewing comparison tool. In that case, you should go with a scope that offers low magnification levels and high levels of magnification. At the moment, the cheapest scopes offer 5x to 40x magnification features.
A standard comparison microscope can have a range from 4x to 400x. They’re perfect for making detailed assessments of your samples, and they’re great for taking pictures too. The higher the magnification level, the lighter your sample needs, so it’s important to be aware of what you want to do with your comparison microscope before you make your purchase.
Wide Field of View:
A high-quality comparison microscope should have a wide field of view. This means that you should see the full slide at once rather than looking at one tiny area. If you can’t see the full slide at once, it will take much longer to arrive at any conclusions about your samples (especially when examining slides). The field of view should be around 3mm to 6mm for an ideal comparison microscope.
You also want to look for a high-quality, objective lens. The glass used in lenses is color tinted, and low-quality glass will tint your images by filtering out certain colors (while adding other colors).

Conclusion:
A quality differential interference microscope will cost around $15,000. This is the most advanced comparison microscope, but you can get better deals on standard comparison microscopes for around $5000. In the eye of the beholder, a comparison microscope is far superior to a compound light microscope.
FAQs:
1) How much does a comparison microscope cost?
A high-quality comparison microscope is a little bit more expensive than a standard compound microscope with one or more objectives. A modern comparison microscope can have as many as 3x objectives that are focused on the same plane. So you’re looking at between $5000 and $15000 for one of these advanced microscopes.
2) What’s the difference between a large-scale comparison microscope and a small-scale comparison microscope?
The most fundamental difference is that the small-scale version with 3x objectives enables you to view three specimens simultaneously, while the larger-scale enables you to view six specimens simultaneously. The larger scale model can also be used for making slides.
3) Are comparison microscopes only available with light microscopes?
Comparison microscopes are also available in fluorescence versions capable of viewing specimens that fluorescent lamps have illuminated.
4) Are comparison microscopes sold with the objectives already installed?
Yes. It’s already included in the scope’s body if you’re looking for a standard comparison microscope. The only difference is whether you want to use two or three objectives. You can either use all three at one time or each objective for different purposes if you’d prefer.
5) What’s the difference between a double- and a triple-head comparison microscope?
A double-head comparison microscope has two objectives that can be swapped out. This is useful for looking at different specimens under different conditions. The triple-option allows you to view three slides simultaneously, either with 3x objectives or using all three objectives for one slide. You can even look at multiple slides with 3x objectives and compare them side by side.
6) How much time will I need to spend adjusting my comparison microscope?
It would be best if you took some time to balance the scope and make sure that everything is aligned correctly before you start looking at anything.
