DEVICE FOR PRECISION LINEAR TRAVEL OF OPTICAL DEVICES Russian patent published in 2009 - IPC G02B7/00 G02B27/62 

FIELD: physics, optics.

SUBSTANCE: invention concerns field of optical instrument making and is intended for an alignment of optical devices in optical systems where it is needed to translocate linearly optical device precisely to itself with diversions no more than 4 angular seconds. This technical effect is provided because four basic laths are mounted with a prestress negative allowance on the basis and the mobile part of the device and forming surfaces of contact for rolling devices in two basic units are anchored. Thus one basic lath is regulated at the expense of introduction of additional devices of adjustment and provides combination of axes of rolling devices travel two basic units in one plane. The angular diversion of the mobile part of the made device at travel on 20 mm has made 3.5 angular seconds.

EFFECT: increase of accuracy of travel of optical devices at the expense of neutralisation of inexactness of manufacturing and the making up of details of the device.
