Lumidigm selects Osram LEDs for fingerprints
Osram's Pointled LED provides uniform, efficient illumination in a compact package for the Mercury, Mariner fingerprint sensor.
Lumidigm has selected the Pointled from Osram Opto Semiconductors as the illumination source in its M-Series.

Lumidigm has a long history in the fingerprint sensor market with its proprietary multispectral imaging technology. The recent adoption of the compact, bright and efficient Osram Pointled has enabled Lumidigm to reduce the size and cost of its sensors and expand the reach of fingerprint authentication into new applications.
Lumidigm has chosen the Osram Pointled to provide a compact, uniform and efficient lighting platform in the company’s M-Series fingerprint sensors.
An innovator in fingerprint biometrics, Lumidigm provides state-of-the-art fingerprint scanning with special emphasis on high performance in real world conditions. The company's patented multispectral fingerprint technology closes a 20% performance gap often seen with conventional technologies because it illuminates both surface and subsurface fingerprint features, ultimately collecting more biometric information from the finger than conventional sensors can.
“We chose the Pointled product from Osram Opto Semiconductors for our Mercury and Mariner product lines because of the unique combination of small package size, symmetric radiation pattern, long lifetime and the ability to operate in high ambient temperatures,” said Steve Corcoran, Lumidigm’s Chief Engineer.
“These attributes made it possible for us to design a compact illumination system that produces a highly uniform and efficient lighting profile at the fingerprint reader platen. Thanks to the excellent output of the Osram Pointled, Lumidigm is able to leverage our multispectral technology in a compact fingerprint sensor series.”
The Osram Pointled is a combination of advanced package and chip technologies and Osram claims it is the smallest LED with an integrated reflector and is suitable for both surface mount technology and zero-height mounting.
The 2 mm diameter x 0.775 mm high module allows the light source to be sunk completely in the printed circuit board, making it ideal for applications such as the Lumidigm M-Series fingerprint sensors where space is at a premium. The typical brightness of the white mini LED is currently 800 mcd at a beam angle of 120°, perfectly suitable for this unique imaging application.
Lumidigm's fingerprint scanners are available worldwide.
