while watching the video. You should be able to get a good, sharp image.

Screwing down too much past the point of good focus can damage the

internal IR filter, so be careful here.

Once you have found a good focus, unscrew the lens until its barrel is

almost out. Then apply a small amount of Lok-Tite or similar

threadlocking compound. These compounds come in several strengths; use

a light-strength one if you intend to remove the lens.

Screw the lens in again until you get a sharp image. Then, let the

threadlocker set, usually about 10 minutes.

Once both lenses are installed, you will need to re-calibrate the device, and

upload the calibration to the STOC. Please see Section

6.8 Replacing and Adjusting CS-Mount Locking

Lenses

Any adjustment or replacement of CS-mount lenses on the STOC should be

followed by re-calibration of the STOC device (Section

8).

CS-mount lenses come with thumbscrew locks for holding the focus and

iris settings. They are set at the factory, usually with the iris wide open and

the focus set to infinity.

If you need to adjust the focus or iris, then it is a good idea to re-calibrate

Adjusting the focus or iris usually results in changing the internal camera

parameters, and the calibration will suffer.

It is easy to replace CS-mount lenses. To remove the lens, unscrew the lens

counter-clockwise. There will be some initial resistance, and then it should

unscrew smoothly.

CS-mount lenses have a 1” diameter, 28 threads-per-inch screw on their

back end. The screw mates with the lens holder opening. To insert a lens,

place its back end on the lens holder opening as straight as possible, and

gently turn it clockwise (looking down at the lens) until it engages the

threads of the lens holder. If you encounter a lot of resistance, you may be

cross-threading the lens. Forcing it on will damage the lens holder or lens

threads.

Once the threads are engaged, continue screwing it on until it seats firmly.

You can snug it down, but do not tighten it excessively, since this can

damage the lens and the lens holder threads.

Normal care should be used in taking care of the lenses, as with lenses for

any good-quality camera.
