Linear Array Pyroelectric Sensors
Linear Array Pyroelectric Sensors

Broadcom has unique capability to produce un-cooled pyroelectric linear array sensors which offer high performance right across the infrared spectrum and especially in the mid infrared. The unique thin film pyroelectric material can be patterned to provide micron-scale individual sensor pixels on the thermally isolating membrane layer of our sensor device.

The linear arrays are housed in a standard metal dual in line 16 pin package, that outputs an amplified, analogue multiplexed signal. The arrays can be supplied with a variety of filter window options including NIR and mid-IR linear variable filters (LVFs), as well as anti-reflection coated Si windows.
