9.3 Do's and Don'ts

As with any optical product, take special care when handling the OPT4048. The device is a piece of active silicon, without the mechanical protection of an epoxy-like package or other reinforcement. This design allows the device to be as thin as possible. Take extra care to handle the device gently to not crack or break the device. Use a properly-sized vacuum manipulation tool to handle the device.

The optical surface of the device must be kept clean for best performance, both when prototyping with the device, and during mass production manufacturing procedures. Keep the optical surface clean of fingerprints, dust, and other optical-inhibiting contaminants.

If the optical surface of the device requires cleaning, use a few gentle brushes with a soft swab of deionized water or isopropyl alcohol. Avoid potentially abrasive cleaning and manipulating tools and excessive force that can scratch the optical surface.

If the OPT4048 performs less than optimally, then inspect the optical surface for dirt, scratches, or other optical artifacts.
