Microscope buying guide

With so many microscope choices on offer, choosing a microscope which suits your students’ learning needs, whilst balancing this with budget constraints can present a challenge.

Where do you start? We have put together a buying guide to microscopes to help you get the very best value for money. Here are the questions you need to ask before buying a microscope.

Have you checked the microscopes you already have in school?

Remember to check the microscopes you already have in stock. Do they meet your students’ needs? Are they still functional? Our technical support team can advise if accessories, spare parts or repairs are available. This first step could ensure you stretch your Science resources budget even further, either for new microscopes, or use it for other items needed for the lab and prep room.

Then, think about what is required from a new addition to the microscope stock.

What is it being used to view?

Firstly, ask what your students are using the microscope to view, as this will narrow down the type of microscope you need.

2D images and slide mounted specimens

Choose a compound microscope, which will enable viewing of specimens which are thin enough to allow light to pass through them.

Typically, this is used for examining slide mounted specimens or pond water specimens such as algae and protozoa.

Compound microscopes provide

·         High power magnification (40x to 1,000x)

·         Narrow field of view

·         A short working distance

3D images such as fossils and dissections

For examining 3D images which are too thick to allow light to pass through, a stereo microscope is needed.

A stereo microscope can be used to view fossils, rocks, coins, insects and more.

In contrast to a compound microscope, a stereo microscope provides

·         Low power magnification (10x to 40x)

·         Wide field of view

·         A long working distance

 

Who will be using it?

Next, ask yourself who is using it, to ensure the right balance of value for money and functionality

Pre-16 students

All Philip Harris microscopes are designed to meet the needs of secondary school students.

For absolute beginners we recommend the Findel Everyday microscope.

Post-16 students

The Philip Harris microscope range is designed to meet the needs of post-16 students too

College and University students

An advanced microscope such as:

Compound – LED light for more demanding use, such as the Optika B-151 Monocular Ecovision LED

Stereo - a digital compound stereo microscope, which has digital imaging capabilities to enable students to document their findings.

Teacher/Demonstrator

A trinocular microscope, any Philip Harris microscope with an integrated digital camera, or a standard microscope with an eyepiece camera.

Other educational, industrial, or hobbyist

Ask our technical support team

 

What type of illumination is needed?

Think about what kind of magnification is to be used and the kind of items the microscope will be used to view, which will determine the light source and bulb type

Low magnification (up to 100x)

Mirror or built-in light source

Higher magnification (100x and over)

Mirror and lamp, or built-in light source

Everyday viewing

Tungsten bulb offers the least expensive, brighter than fluorescent option

Viewing live specimens

LED bulb offers a cool, even light with a long life (5,000-10,000 hours)

 

How will the microscope be used?

Sitting or standing, using the microscope for extended periods of time, linking to a computer, or a third person viewing. How the microscope is used influences the kind of head needed

For short periods of time, for standard viewing

Monocular head

For extended periods of time, to reduce eye strain

Binocular head

Whilst user is seated

Inclined head

Whilst user is standing

Vertical head

Linking to a computer, display or television

Digital microscope

With a third person (eg teacher) or camera viewing

Trinocular microscope

 

Microscope shopping list

Once all the questions above are considered, use a handy checklist to narrow down the microscope needed. An example is below

 

Your answer

Compound or stereo microscope

 

Age range using the microscope

 

Illumination needed

1.       Low or high magnification

2.       Tungsten or LED bulb

 

Head type

1.       Number of heads – monocular, binocular or trinocular

2.       Inclined or vertical head

3.       Linking to a computer or display – yes / no
