History
An early digital microscope was made by a lens company in Tokyo, Japan in 1986, which is now known as Hirox Co Ltd. It included a control box and a lens connected to a computer. The original connection to the computer was analog through an S-video connection. Over time that connection was changed to Firewire 800 to handle the large amount of digital information coming from the digital camera. But some of their current advanced versions are all-in-one and do not require a computer. The most advanced all-in-one systems now have HD monitors built-in.
Invention of the USB port resulted in a multitude of USB microscopes ranging in quality and magnification. They continue to fall in price, especially compared with traditional optical microscopes. They offer high resolution images which are normally recorded directly to a computer, and which also use the computer for its in-built LED light source. The optical resolution is directly related to the number of megapixels available on a specific model, from 1.3 MP, 2 MP, 5 MP and upwards.

“So in accepting the leading of the sentiments, it is not what we believe concerning the immortality of the soul, or the like, but the universal impulse to believe, that is the material circumstance, and is the principal fact in this history of the globe.”
