D.B. Milliken Boresight Model B-02

The D.B. Milliken Boresight Model B‑02 is a precision accessory originally made by the Milliken company in Arcadia, California. It appears primarily in imagery and collections tied to 16 mm high-speed cine cameras (like the DBM‑5 series), serving as a boresight alignment tool. It was used to calibrate camera alignment by providing a fixed reference point—essential for accurate filming in high-speed or technical setups.

Camera technicians would install the B‑02 boresight into the camera’s optical path to ensure that lenses, shutters, and framing were precisely aligned before shooting. This was critical when capturing rapid events (e.g., rocket tests), where timing and frame consistency were paramount.
