The 80040 is an excellent choice when transitioning from a collimated beam of light into a fiber (or visa versa), when working in the infrared. An advantage of the 80040 is that it does not require optical alignment. Simply connect the fiber optic cable and it is ready to use. Its 1.5-Inch Series female flange is compatible with a variety of products, including Oriel FT-IR Spectrometer Modular solution. An off-axis parabolic reflector is integrated into the design, rather than a condenser 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 fiber positioned at the focal point. This type of reflector provides very efficient radiation control because collection or focus occurs over very large solid angles. This makes the 80040 particularly useful with lower power incoherent sources, such as the Silicon Carbide or QTH infrared sources.

当在红外工作时，80040是一个很好的选择，从一束平行光束转换为光纤(或者反之亦然)。80040的优点是它不需要光学校准。只需连接光纤电缆即可使用。其1.5英寸系列凸缘与各种产品兼容，包括Oriel FT-IR光谱仪模块化解决方案。设计中集成了离轴抛物面反射镜，而不是冷凝器透镜。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，完全进入反射器焦点区域，并且在焦点上没有光纤的阴影。这种类型的反射器提供了非常有效的辐射控制，因为收集或聚焦发生在非常大的实心角度。这使得80040特别适用于低功耗非相干源，如碳化硅或QTH红外源。
