What's the difference between eyepiece and optigraph?
Eyepiece
Definition:
(n.) The lens, or combination of lenses, at the eye end of a telescope or other optical instrument, through which the image formed by the mirror or object glass is viewed.
Example Sentences:
(1) Cortical cell length and diameter were measured using a microscope and eyepiece micrometer; measurements were conducted "blind."
(2) The sperm count can be made rapidly and directly from an undiluted, preheated sample by counting spermatozoa in the area of a grid located within the eyepiece; the count is expressed in millions per milliliter.
(3) Field tests involving 60 eyepieces demonstrated effective disinfection by a Chi-Square statistical comparison, at values greater than 95% confidence level, as compared to unirradiated eyepieces.
(4) It is very important that a patient himself can observe velopharyngeal movements through the eyepiece of the fiberscope in order to do self exercise.
(5) Higher correlation coefficients within and between observers were obtained using the cine method compared to the 70 mm visual and eyepiece techniques.
(6) Thus, it is now possible, as one scans the microscopic field, to look past the static images of red- and blue-stained cells and appreciate a dynamic and detailed medley of molecularly defined events emanating from the eyepiece.
(7) Airway luminal diameter was directly measured at diminishing transbronchial pressure (closing) and increasing transbronchial pressure (opening) by means of a stereomicroscope with a calibrated eyepiece.

(18) This paper offers the quantitative morphological data (light-optical morphometry with the aid of a graduated eyepiece micrometer) of some mesenchymal children tumours.
(19) A pair of small heaters were designed to clamp over the eyepiece tubes of a standard operating microscope and their effectivity assessed.
(20) It images a dot on the center of the lens under test on the scale in the eyepiece.
Optigraph
Definition:
(a.) A telescope with a diagonal eyepiece, suspended vertically in gimbals by the object end beneath a fixed diagonal plane mirror. It is used for delineating landscapes, by means of a pencil at the eye end which leaves the delineation on paper.
