Gaskets

Gaskets are recommended for providing optical isolation and dust protection.

However, gaskets can impede FOV and place unwanted stress on the module or the

individual sensor lens holders.

Gasket static force can deform the cosmetic baffle/lens holder resulting in poor image

quality and permanent damage to the camera. Gaskets placed on the R200 housing

can transfer chassis flex into the camera module causing loss of depth data. Gasket

thickness has a large effect on the static force applied to the module surface. The

thinner the seal, the greater the static force applied. Once the gasket is compressed,

the static force will increase exponentially.

7.8.3

Optical Isolation

Note: It is recommended to isolate the module cameras and IR projector from each other.

Not properly isolating the cameras can result in leakage light as shown in Figure 7-6.

To light leakage, it is recommended to use a gasket material in between the rear

cover holes and the module as shown in Figure 7-7. The gasket material needs to be

compliant so that it does not transmit chassis flex forces to the module.

In addition, light can transmit through a single piece of cover material. Using separate

cover material pieces with physical partitions for each opening minimizes the ability of

light to transmit through the cover. Refer Figure 7-8 for reference.
