Levenhuk D320L PLUS is a microscope with a 3.1M digital camera. The microscope is designed for conducting professional laboratory research. Moreover, it is an excellent choice for holding lectures and seminars in colleges and universities. The microscope is suitable for visual observations and, what's more, it allows for recording and saving them as pictures or videos. All the necessary accessories are already included in the kit.
This microscope comes with a classic monocular 360° rotatable head. Two eyepieces with different magnification allow for changing magnification power. Each wide-angle eyepiece features a pointer. The objectives are achromatic, you can use a 100x objective for oil immersion (a bottle with immersion oil is included in the kit). Observations are performed in the transmitted light. The optics feature a 40–1600x magnification range.
To adjust the sharpness, a coaxial mechanism of coarse and fine focusing adjustment is used. A stage can be moved along two axes. It is equipped with a mechanical scale. Under the stage, there is an Abbe condenser with iris diaphragm and LED illumination with adjustable brightness. The illumination can be powered by an AC supply as well as by batteries.
A 3.1M digital camera is connected to a computer with a USB cable. A special software program included in the kit allows for shooting videos, taking pictures, and processing them. The maximum image resolution is 2048x1536 pixels. A camera is installed in the optical tube instead of an eyepiece.
