Simplifying the Microscope Buying Process
Purchasing a microscope may seem complicated, but understanding a few key concepts can simplify the process. Microscopes can be grouped under two major categories: stereo and compound microscopes. The differences are based on optical design and application, and the main features of each are shown below.
Compound Microscopes
- Optical system comprised of objective (primary) and eyepiece (secondary) magnifications
- Single light path produces two-dimensional image
- High magnification (40x to 1,000x)
- Short working distance
- Upright configuration for viewing prepared slides; inverted design for viewing culture vessels
- Also called optical or light microscopes
Stereo Microscopes
- Available in fixed magnification and zoom versions
- Independent right and left light paths
- Three-dimensional image (stereoscopic)
- Low magnification (2x to 300x)
- Longer working distance
- Designed for viewing larger “macro” objects (insects, plants, etc.)
- Also called dissecting microscopes
Digital Microscope Capabilities
When you determine the right microscope category for your application, consider whether a digital camera or digital microscope system is right for you. Features of these increasingly popular integrated systems include:
- Built-in camera for image capture
- Touchscreen or integrated screen
- Multiple users can view samples simultaneously
- Send output to external monitors for training and teaching
- Connections via Wi-Fi and Bluetooth
- Cloud-based image storage and sharing options
Other Key Considerations
Consider these details and options when making your purchasing decision.
- Illumination source: LED, halogen and others
- Contrast technique: brightfield, phase contrast, darkfield, polarization or fluorescence
- Lens/Objectives: achromat, plan achromat or plan fluor optics
- Customization
- Ergonomics
- Price
