Opto Diode launched infrared emitter and also a detector

Optoelectronic sensor specialist Opto Diode has launched a new infrared light-emitting diode packaged in a highly heat dissipating robust TO-66 package. The new device OD-669 is made using the material gallium aluminum arsenide (GaAlAs) and can emit infrared in the wavelength of 880 nm at a half intensity beam angle typically of 120 degrees. Nine IR emission chips are connected in series and is packaged in a electrically-isolated case. These devices are suggested far covert aircraft lighting or covert anti-collision lighting in aviation applications.

At a current of 300 mA, this device can produce output power in the range of 390 mW to 500 mW (typical). With a spectral bandwidth at 50% is 80 nm, this device forward voltage is in the range of 13.5 volts (typical) to 15 volts (maximum) and a reverse breakdown voltage
of minimum 5 volts and 30 volts (typical). Equivalent Capacitance is 11 Pf and a rise time and fall time is typically 3 sec. Thermal parameters include the storage and operating temperature ranges of -55 C to 100 C and the maximum junction temperature of 100 C.

A few weeks earlier to the above products announcement, Opto Diode has also announced the new BXT2S-68TE, a thermoelectrically-cooled (TEC), two-stage infrared (IR) detector for applications such as gas analysis, emissions monitoring, and process control.

With an active area of 6 mm x 6 mm (36 mm), this new lead selenide (PbSe) material based infrared sensor available in TO8 package with a flat sapphire window.

Opto-Diode offering wide choice of devices with Peak sensitivity Wavelength range starting from 3.6 m to 3.8 m,and on the other side devices with Peak sensitivity Wavelength range of 4.3 m to 4.5 m. The responsivity of these devices is in the range of from 1.65 x 10 4 V/W (minimum) to 2.5 x 10 4 V/W (typical).
The device features minimum detectivity (D) of 1.5 x 1010 , resistance ranges from 1.0 to 15.0 Mohms, and a typical response time of 12 sec.

Opto Diode says its B-Series cooled IR detectors offer superior sensitivity for extremely low-level signal detection and exceptional stability in environments where fluctuating temperatures exist. They are ideal for applications such as spectroscopy, process control, gas analysis and emissions monitoring.

The BXT2S-68TE element operating temperature is -25 C; absolute ratings for storage and operating temperatures range from -40 C to +85 C.
