The TETRAVIEW 5MP Digital Microscope with 180° TFT LCD Display from Celestron features a 5MP digital camera, achromatic objectives on a rotating turret, a 180° rotating TFT LCD display, and cordless operation option. The objectives have magnifications 4x, 10x, 20x, and 40x and contain optics made of achromatic glass. The achromatic optical glass reduces color distortions and provides images with a better clarity and detail than plain optical lenses. Instead of an eyepiece, this microscope has a Thin-Film-Transistor (TFT) LCD touchscreen which rotates 180°. This type of LCD improves addressability and contrast. The built-in 5MP digital camera delivers up to 400x on-screen magnification without digital zoom. With the 4x digital zoom, it delivers total magnification of up to 1600x. You can view your specimens via an integrated 4.3" display, capture images and videos, or save them to external memory. The microscope has an SD card slot which supports up to 32GB of memory. It also features an AV/TV and USB output ports which enable you or your audience to view images or videos on a larger screen. Additionally, the microscope can be used in a cordless operation mode using four AA batteries, but does not have a built-in charger.
The mechanical 3.5 x 3.5" stage features two precision X-Y position controls with scale and two metal brackets to hold and align your slides. To provide lighting for your slides, there is a bottom LED illuminator with controllable brightness and 0.65 NA condenser for collimating a light cone. To allow you additional control over image detail, sharpness and contrast of different visual features and sample layers, this microscope is equipped with a six-position filter wheel with red, blue, and green filters, and three diaphragms with different size apertures. Be aware that switching objectives will change working distance from the objective tip to your sample dramatically.
Also included with the microscope are seven prepared slides, a stylus, a 2GB SD memory card, a USB cable, an AC power supply with international plugs, a dust cover, and a hard case.
