The term "15 x 80 biocular" typically refers to binoculars that have a magnification of 15x and an objective lens diameter of 80mm. This means that objects viewed through these binoculars will appear 15 times closer than they do to the naked eye, and the larger lens diameter allows for better light transmission, making them suitable for low-light conditions. These specifications make such binoculars ideal for activities like birdwatching or stargazing.
The eyepiece of a microscope is the top part of the microscope in which you look through to see your magnified object. There is no other name for the eyepiece The eyepiece holds the ocular lens. If there are two eyepieces (one for each eye) they are called biocular lenses.
