紫外线冷镜
紫外线冷镜与标准冷镜略有不同，但它们可以有效反射紫外线，并透射可见光和红外线。它们通常以45°角使用，非常适合要将紫外光与可见光和近红外光分开的应用。

冷镜
冷镜是热镜的反面，它反射可见光并透射红外光。 它们的涂层都是D一面的，并且像热镜一样，也沉积在低膨胀率的材料上，例如硼硅酸盐玻璃。 这些反射镜通常在随机偏振光中以45°入射角使用。

热镜
热镜按其名称说明执行：它们反射热量并透射可见光。 所有涂层均被归类为坚硬的D一表面电介质，并且将达到或超过规定的湿度和磨损规范。 为防止高温应用导致开裂或开裂，所有涂层均沉积在低膨胀材料（例如硼硅酸盐玻璃）上。

红外抑制滤光片
这些滤镜与热镜非常相似，但其红外阻隔范围更长。通过将电介质堆栈的反射与IR吸收滤光玻璃的吸收相结合，可以实现这种扩展的阻挡范围。由于这种吸收系数，这些滤波器仅在Z高滤波器温度不超过100°C的低功率应用中有用。
