New optoelectronic devices for the Mid-Infrared spectral range open completely new possibilities for portable sensors creation. Using Mid-infrared LED-PD optopairs allows developing an instrument that is smaller, less expensive and versatile.

Packages for LEDs

Generally LEDs are mounted in the package that provides two electrical leads, a transparent optical window for the emission and heat-sinking. An LED chip is soldered/glued to the package surface that is connected to the one of the lead wires. Top contact of the chip is connected to the other lead with a bonding wire.

We offer a range of standard and customized TO- and SMD-type packages:

TO-18 – for mounting one-element LEDs, single-wavelength matrices, 2-wavelength matrices
