| ||||||
MOB-1-15x Filar Micrometer is constructed using a standard compensating ocular AM-27, magnification of 15x with the two scales placed at the intermediate image plane. | ||||||
Graphic representation of the two scales, both superimposed onto the intermediate image plane | ||||||
|
||||||
The actual view of both scales looking down the ocular, normally they are superimposed with the image of the observed object |
||||||
|
||||||
Using filar micrometer in combination with an object micrometer, such as shown above, one can do very accurate measurements |
||||||
|
||||||
The short tube is intended for use with Biolam-M, the metallographic microscope which has 190 mm TL, and is used to replace standard tube of the monocular when using MOB-1-15x with objectives for 160 mm TL |
