Maximum Lens Dimensions

When mounting a lens on the dart S-mount or CS-mount camera models, observe the following:
The lens must not intrude into the camera body more than the values given below.

Camera Model
daA1280-54bm
daA2500-14bm
daA1280-54bc
daA2500-14bc
daA1600-60bm
daA1600-60bc
Table 4: Maximum Allowed Lens Intrusion for dart BCON Camera Models
The length of the threads on the camera's lens adapter is 7.5 mm for dart S-mount camera

models and 5.6 mm for dart CS-mount camera models.
For S-mount camera models, Basler recommends attaching an O-ring (Ø11 mm x Ø1.5 mm) to

the S-mount lens. This makes it easier to adjust the lens.
The CS-mount variants of the daA1600-60bm/bc cameras are shipped with a 0.5 mm spacer

ring. The spacer ring optimizes the flange focal distance of these cameras. When mounting a
lens on the camera, attach the spacer ring to the lens.
The maximum lens dimensions are also shown in Figure 12 on
Screwing in the lens too deep can damage camera components.
On S-mount cameras, the lens is screwed in and out to reach the desired level of focus.
S-mount lenses do not have a defined flange and therefore will not stop before they touch (and
possibly scratch or break) the sensor glass.
