OTP-538U
Introduction
The OTP-538U is a thermopile sensor in classic TO-46 housing.
The sensor is composed of 116 elements of thermocouple in series on a floating micro-membrane having an active diameter of 545 μm and with blacken surface to absorb the incident thermal infrared radiation, which induces a voltage response at output terminals.
The sensor chip is fabricated by a unique front-surface bulk micromachining technology, which result in smaller size and faster to response ambient temperature change.
The IR window is a bandpass filter having its 50% cut-on wavelength at 5 μm, and cut-down at 14μm.
The sensor responses pr...
