Allied Vision Technologies Helps Laetus with Camera Cure-all

Laetus has begun using Allied Vision Technologies’ Stingray camera in its automated testing control systems for the pharmaceutical industry.
One standard camera alone could not fulfill the complex requirements of several different systems which had previously, and for good reason, made use of different cameras. A new development was needed, completely customized to fit Laetus’ ideal camera module needs.

To replace angle- and straight-mount varieties, two FireWire ports had to be positioned at 90° angles.
To reduce cabling, the I/O port was eliminated. In its place, an additional trigger board circuit needed to be housed within the unit, allowing the camera to be triggered instantaneously using a hardware signal via FireWire connection. Two modular designs were needed: one with a conventional C-mount lens adapter and one with a compact M12 lens and an integrated LED light source.

From these specifications arose the Laetus iCAM, a compact camera module with an integrated LED flash. Inside the 100 x 60 x 40 mm housing are a modified AVT Stingray Board Level camera, a small M12 lens, and a two-color LED flash. Illumination with red, white or UV LEDs is directly controlled by the camera and calibrated to its exposure time.

The iCAM is available in eight sensor varieties with resolutions from VGA (0.3 megapixels) up to 5 megapixels. Lens focus with 6, 8 or 12 mm focal length allows for perfect image quality using Allen screw adjustment. Alternately, the camera is available without the integrated flash, using a standard C-mount lens adapter instead.
