Microscopes

A microscope opens up a layer of the world you cannot otherwise see. Cells, fibres, insect parts, mineral crystals, electronics. Picking the right type depends on what you want to look at and how serious you are about it.

Compound microscopes

Use two lens systems to magnify slides at 40x to 1000x or more. Standard for biology, medical training, and serious hobby use. Look down through an eyepiece at a thin sample on a glass slide. Best for cells, bacteria, blood, plant sections.

Stereo microscopes

Lower magnification, typically 10x to 80x. Show the object in 3D from two slightly different angles. Used for dissection, jewellery, electronics repair, coin and stamp inspection. Work with objects you can hold rather than slides.

Digital microscopes

Use a built-in camera and a screen instead of an eyepiece. Magnification 50x to 1000x. Better for sharing what you see, recording video, and saving images. Standard for modern classrooms and quality control work.

USB microscopes

Plug into a laptop or tablet. Small, portable, and inexpensive. Good for hobbyists, students, and field inspection. Image quality varies widely with price.

Choosing magnification

• 10x to 80x. Stereo work. Coins, stamps, electronics, dissection.
• 40x to 400x. School biology, basic cells, plant samples.
• 400x to 1000x. Bacteria, blood smears, advanced biology.
• Above 1000x. Specialist research. Not recommended for hobby use.

Light source matters

LED is now standard. It runs cool, lasts decades, and gives consistent colour. Older halogen and tungsten microscopes still work but bulbs are expensive to replace.

Picking for a beginner or student

For a child or first-time user, a stereo microscope with LED is the best starting point. It shows real objects, not slides, and is easier to focus. Step up to a compound microscope once they want to see cells.
