Fine grinding produces a surface with little deformation that can easily be removed during polishing. Because of the drawbacks with grinding papers, alternative fine grinding composite surfaces are available, in order to improve and facilitate fine grinding, A high material removal rate is obtained by using grain sizes of 15, 9.0 and 6.0 µm.

The normal pupil size in adults varies from 2 to 4 mm in diameter in bright light to 4 to 8 mm in the dark. The pupils are generally equal in size. They constrict to direct illumination (direct response) and to illumination of the opposite eye (consensual response). The pupil dilates in the dark. Both pupils constrict when the eye is focused on a near object (accommodative response).

Your pupil has a maximum size of about 0.5 cm, so the light-gathering power of an 8" telpe (diameter 20.3 cm) is LGP = (20.3/0.5) 2 = 1650. The main function of the telpe is to take all of this light and concentrate it into your eye (or an equivalent camera).

long been realised by the population at large, and by 1300 the trade of lens-grinding was widespread enough to require formal guilds and regulations. Although popular and effective, no one was quite sure of the mechanics of it all. The %rst detailed mathematical explanation would not come until Johannes Kepler published his work on optics in 1604.
Curiously, the 13 inch f/3 has about the same degree of parabolization as the 20 inch f/5. So if you can make a somewhat larger mirror, then you can be confident in attempting a somewhat smaller f/3 mirror. My goal in grinding, polishing and figuring a mirror is to make it indistinguishable from perfect.
Metal bonded diamond grinding wheels are very important for precision grinding operations of hard and brittle materials especially like ceramics or cemented carbides. But the trueing and dressing problem has affected its wide use. In this paper, a new EDD (Electrical discharge dressing) device was developed for the dressing of metal bonded diamond arc grinding wheels.
