Celestron TetraView LCD Digital Microscope

40x-1600x Magnification with 4 Achromatic Objectives

The TetraView is built around a classic compound microscope design, featuring a rotating turret with four DIN standard achromatic objectives: 4x, 10x, 20x, and 40x. This optical system provides a magnification range ideal for viewing cellular structures, microorganisms, and other specimens on prepared slides. When you need to examine finer details, a 4x digital zoom extends the total magnification up to 1600x, revealing intricate features that would otherwise be invisible.

5MP Sensor and 4.3" Rotating Touchscreen

At the heart of the TetraView is a 5MP CMOS sensor that captures still images up to 3648x2048 resolution and VGA (640x480) video. All functions are controlled through the intuitive 4.3” TFT touchscreen, which can rotate 180 degrees. This rotation makes it easy to share your findings with a colleague or engage a classroom without anyone needing to leave their seat.

• 5MP CMOS Sensor: The 1/2.5" sensor with 2.2 µm pixels provides the resolution needed for detailed analysis and documentation.
• 180° Rotating Screen: Easily share the live view with others in a lab or classroom setting, promoting collaborative work.
• Touchscreen Control: Navigate menus, adjust settings, and trigger image capture directly on the 480x272 pixel display.

88mm x 88mm Mechanical Stage with Dual Focus Control

Specimen handling is precise and repeatable thanks to a fully mechanical stage and dual-speed focusing. The 88mm x 88mm stage includes metal clips to securely hold your slide, while X-Y controls allow for smooth, measured movements. Coarse and fine focus knobs let you quickly find focus and then make minute adjustments for a perfectly sharp image, critical at higher magnifications.

• Fully Mechanical Stage: Provides precise X-Y positioning of the slide for systematic examination of specimens.
• Adjustable Illumination: Dual top and bottom LED illuminators with adjustable brightness ensure optimal contrast for any sample.
• Integrated Filter Wheel: A built-in wheel offers red, blue, and green filters, plus 1mm, 3mm, and 6mm apertures to further control illumination.

Onboard 8GB Storage and TV/USB Output

The TetraView is a self-contained imaging station. It ships with an 8GB SD card (and supports cards up to 32GB) to store thousands of images or hours of video without needing a computer. For presentations or group instruction, the TV-out port lets you connect to a television or projector for a large-format live view. When you're ready to archive or process your data, the USB 2.0 port makes transferring files to your PC or Mac simple.

TetraView vs. Handheld Microscopes: High-Power for Slides

It's important to choose the right tool for the job. The TetraView is a high-power compound microscope designed specifically for viewing translucent specimens on glass slides. Its magnification range of 40x to 1600x is ideal for biology, forensics, and material science applications where cellular detail is key.

In contrast, low-power handheld digital microscopes are better suited for observing the surface of opaque, 3D objects like coins, stamps, or circuit boards. The TetraView's transmitted light system and high magnification are not designed for these types of objects, making it the superior choice for serious slide-based microscopy.
