In the world of medical imaging, minute changes can literally mean the difference between life and death. Precise imaging allows physicians to make accurate diagnoses quickly and with confidence when treating patients with a variety of potentially life-threatening conditions.
The client: The client was in the medical imaging industry, where a minute difference could literally mean the difference between life and death.
The challenge: To track recovery, photos needed to be taken of the same area, in the same position, on a series of successive appointments. To guide the camera, two 12mm diameter, sharply focused spots of light needed to converge on the skin of a patient 1m away.
The clients competition had a similar project, so they were working to a strict time and budget.
The solution: Using a bulk stock mount, we accurately centred the LED by modifying the mount so it engaged with the LEDs integral lenses, rather than with its circuit board. The light from the LED then travels through a precision 350 micron pinhole, which gives the correct spot size and focus. The end result is a modular solution that can be easily adapted to allow different spot sizes and shapes for a range of distances.
Having made the prototypes in house, the transfer to volume production was seamless. Use of mass-produced and stock components kept costs and lead times minimal, and kept the product easily adaptable.
