4.3" Full-Color 180° Rotatable LCD Touchscreen 5MP CMOS Sensor for High-Resolution Imaging 40x to 1600x Magnification Range Fully Mechanical 88mm x 88mm Stage with Metal Clips Capture Images and Video to Included 8GB SD Card TV Output for Live Viewing on Monitors or Projectors Description FAQ Specifications In the Box Downloads Warranty Celestron TetraView LCD Digital Microscope The Celestron TetraView LCD Digital Microscope replaces a traditional eyepiece with a 5MP CMOS sensor and a 4.3" rotating touchscreen, allowing you to capture detailed images and VGA video directly to the included 8GB SD card. Its four achromatic objectives deliver an optical magnification range of 40x to 400x, which extends up to 1600x using the 4x digital zoom. The 88mm x 88mm fully mechanical stage and dual coarse/fine focus knobs give you precise control when examining any of the 7 included prepared slides. 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. What kind of specimens is the Celestron TetraView LCD Digital Microscope best for? The TetraView is a high-power compound microscope designed for viewing translucent specimens on microscope slides. It excels at observing biological samples like bacteria, cells, and microorganisms in pond water, as well as prepared slides from various scientific disciplines. It is not suitable for viewing opaque, solid objects like coins or insects. How do I save and transfer images from the TetraView microscope? Images and videos are saved directly to an SD card. The microscope includes an 8GB SD card and the slot supports cards up to 32GB. To transfer files, you can either remove the SD card and use a card reader or connect the microscope to a computer using the included USB 2.0 cable. Can I view live images from the Celestron TetraView on a larger screen? Yes. The TetraView features a TV/Video out port that allows you to connect it to a television, monitor, or projector. This is an excellent feature for classroom teaching, lab presentations, or group demonstrations where you want to share the live view with a larger audience. What is the maximum magnification of the TetraView and how is it achieved? The TetraView has a maximum optical magnification of 400x, achieved using the 40x objective lens. The total maximum magnification of 1600x is reached by applying the 4x digital zoom. While optical magnification provides the highest level of detail, digital zoom is useful for enlarging the center of the image for closer inspection. Can I use the Celestron TetraView to examine pond water samples for microorganisms? Absolutely. The magnification range of the TetraView, starting at 40x, is perfect for observing protists, amoebas, and other microorganisms found in pond water. You would place a drop of water on a blank slide with a coverslip and use the mechanical stage to systematically scan the sample. Is the TetraView LCD Digital Microscope suitable for looking at the details on a coin? No, the TetraView is not the right instrument for this task. It is a high-power transmitted light microscope, meaning light must pass through the specimen. For opaque objects like coins, stamps, or circuit boards, a low-power stereo or handheld digital microscope with reflected top-down lighting is the appropriate tool.
