Frankfurt Laser Company is pleased to announce a new line up of LEDs and accompanying photodiodes (PDs) to its range. Both LEDs and PDs operate in the mid infrared range from 1.58μm to 4.45μm.

Due to advances in measuring technology these LEDs are ideally suited for use in gas measurement; this can be measuring the concentration of a particular gas or the existence of a particular gas type within air. Such sensors offer a reliable, instant and non-contact method of gas detection. The individual LEDs and photodiodes are cost-effective and are small enough to be integrated into the smallest of packages. Operating over a wide temperature range allows them to be used in a variety of environments.

LEDs can be either used in Quasi CW or pulsed mode operation to obtain either a high average power output or a high peak power output.

As an addition to the package options, which are TO18 and TO5, both LEDs and PDs can be equipped with a parabolic reflector to either decrease beam divergence or increase the light gathering power respectively.

With a complete set of drive electronics available, this allows an easy set-up solution to enable quick and easy experimentation.
