Frequently Asked Questions (FAQ) – Transmitted-light Microscopes

1. What is a transmitted-light microscope?

A transmitted-light microscope (also known as a bright-field microscope) uses light passing through a transparent specimen, allowing observation of fine structures such as cells, tissues, or microorganisms – with high magnification and resolution.

2. How does it differ from a stereo microscope?

A transmitted-light microscope generates a two-dimensional image and is used for small, transparent objects at high magnification. In contrast, a stereo microscope provides a three-dimensional view, lower magnification, and is ideal for solid objects and micro-manipulation.

3. Which light source is recommended?

KERN uses modern LED technology – energy-efficient, long-lasting, and offering uniform illumination. Many models offer adjustable brightness and require little maintenance – perfect for continuous use in labs or classrooms.

4. Can I digitally upgrade a transmitted-light microscope?

Yes – many KERN microscopes can be retrofitted with a C-Mount camera. A suitable adapter enables live image streaming, image capture, and digital classroom use. KERN offers a variety of digital camera options with USB, HDMI or WLAN connectivity, including software for image capture, measurement and archiving.

5. What is a C-Mount camera?

A C-Mount camera is a digital camera with a standardised 1″ threaded mount designed for microscopes and optical systems. Depending on the model, it connects via USB, HDMI or WLAN.

Advantages:

• Flexible retrofitting using adapter
• Compatible with many KERN microscopes
• Ideal for live viewing, analysis and digital documentation

6. What accessories are available?

Accessories include:

• Interchangeable objectives & eyepieces
• LED illuminators & filters
• Microscope cameras & tablet adapters
• Dust covers & calibration sets
• Mechanical stages & ergonomic stands
