Market Applications:

•

IR touch panels for devices such as printer displays, eBook readers, smart phones, tablets,

ultrabooks, and GPS units

The Perspective:

With their low profiles of 1 mm, the VSMG10850, VSMB10940, and VEMD10940F are optimized for

use in IR touch panels in a wide range of devices. Offered in clear, untinted plastic packages, the

940 nm VSMB10940 and 850 nm VSMG10850 IR emitters provide high radiant intensity of 1 mW/sr

typical at 20 mA – up to 33% higher than comparable devices on the market – and fast switching

times of 15 ns. Offering high radiant sensitivity from 780 nm to 1050 nm, the VEMD10940F

photodiode features a daylight blocking filter matched with 830 nm to 950 nm IR emitters, including

the VSMG10850 and VSMB10940.

Availability: Samples and production quantities of the new IR emitters and photodiode are available

now, with lead times of six to eight weeks.
