With its broad spectral response covering the entire range of the 80350 FT-IR scanner, the model 80008 Deuterated L-alanine doped Triglycine Sulphate (DTGS) detector is a good choice for many mid-IR applications. There is no need to worry about using liquid nitrogen - this pyroelectric detector operates at room temperature while still achieving good sensitivity. An off-axis parabolic reflector is integrated into the design, rather than a focusing lens. IR refractive optics are expensive and have transmittance limitations. Using this type of reflector provides several advantages: its gold coating enhances IR reflectance, the focal point is displaced from the mechanical axis, giving full access to the reflector focus area, and there is no shadowing with the detector’s active area positioned at the focal point. This DTGS detector is optimized for use with the Oriel 80007 silicon carbide IR source. Fine gain adjustments can be made via an internal potentiometer, if desired.

80350 FT-IR扫描器具有广泛的光谱响应范围，80008型氘化l -丙氨酸掺杂硫酸三甘氨酸(DTGS)探测器是许多中红外应用的良好选择。不用担心液氮的使用——这种热释电探测器在室温下工作，但仍然具有良好的灵敏度。设计中集成了一个离轴抛物面反射器，而不是聚焦透镜。红外折射率光学是昂贵的，并具有透射率的局限性。使用这种类型的反射器提供了几个优点:它的金色涂层增强了红外反射率，焦点从机械轴移开，可以完全进入反射器的焦点区域，并且在焦点位置没有探测器的活动区域的阴影。该DTGS探测器是优化使用Oriel 80007碳化硅红外源。如果需要，可以通过内部电位计进行微调。
