Collimator Tube F420 is a type of optical instrument which has a focus of 420mm and is used for obtaining parallel beams.
*Introduction:<o:p>
When combined with different reticles, accessories, micrometer eyepieces or microscope systems,
it can be used for measuring the imaging quality and focus of lens and other optical systems or
for checking the uniformity of optical glasses. <o:p>
1) Used as the tool for installing, correcting, adjusting and checking optical measuring instruments. <o:p>
2) When equipped with dedicated ranging reticle (bolo-oard) and micrometer eyepieces,it is <o:p>
able to measure distances, and when using Bolo-board, able to measure the focus of lens. <o:p>
3) When equipped with various detectability plates and microscopes, it can be used for
measuring the detectability of photographic lens or microscopes.<o:p>
4) When equipped with star point board and microscopes, it can be used for checking the
imaging quality of lens or other devices. <o:p>
5) When equipped with special flat mirrors and micrometer eyepieces, it can also be used
for measuring the linearity of rails and large surfaces. <o:p>
