Non-magnetic mounting
The 185-10 mirror is often used to verify infinity focus. It may be held in front of the objective lens of any of our transits or levels in order to provide an infinity focus reference, assuming that the instrument is lit internally using one of our lighting attachments. The reflected reticle image then comes into view when the instrument is focused at infinity.
This fused quartz, first surface mirror is optically flat to ¼ wavelength of sodium light, and mounted in a brass holder with a flange on the front surface. Foam lined plastic case is included.
Note: This mirror is not magnetic. For magnetic-backed mirrors, please see our 6202 or 6204.
