Imaging Resource has an article on a new toy recently delivered to technicians at LensRentals.com. (It should tell you something that the writers at Imaging Resource call the article a "Nerd Alert".)
The "toy" is a custom designed machine from Optikos designed to facilitate calibration of camera lenses.
The machine works by shining three pin-point sized light beams through the lens. The first beam travels straight through the lens assembly. The other two beams hit the lens at an angle. The sources for these two beams can be adjusted to change the angle at which the beam hits the lens.
The machine then produces a display showing the effect of shining the light beams through the camera. These results can be use to determine whether the lens is off-center. If the lens needs to be calibrated, it also produces real-time feedback while the lens is being calibrated.
The real-time feedback aspect promises to greatly decrease the amount of time needed to calibrate an off-centered lens.
LensRentals.com currently only rents equipment. They don't offer repair or calibration services. (They do sell their rental equipment after owning it for two year if you happen to be in the market for used lenses or camera bodies.)
The machine does seem to be something other companies might be interested in, including those that offer repair services.
Check out the LensRentals.com blog to see the machine in use.
