紫外線冷鏡
紫外線冷鏡與標準冷鏡略有不同，但它們可以有效反射紫外線，并透射可見光和紅外線。它們通常以45°角使用，非常適合要將紫外光與可見光和近紅外光分開的應用。

冷鏡
冷鏡是熱鏡的反面，它反射可見光并透射紅外光。 它們的涂層都是D一面的，并且像熱鏡一樣，也沉積在低膨脹率的材料上，例如硼硅酸鹽玻璃。 這些反射鏡通常在隨機偏振光中以45°入射角使用。

熱鏡
熱鏡按其名稱說明執行：它們反射熱量并透射可見光。 所有涂層均被歸類為堅硬的D一表面電介質，并且將達到或超過規定的濕度和磨損規范。 為防止高溫應用導致開裂或開裂，所有涂層均沉積在低膨脹材料（例如硼硅酸鹽玻璃）上。

紅外抑制濾光片
這些濾鏡與熱鏡非常相似，但其紅外阻隔范圍更長。通過將電介質堆棧的反射與IR吸收濾光玻璃的吸收相結合，可以實現這種擴展的阻擋范圍。由于這種吸收系數，這些濾波器僅在Z高濾波器溫度不超過100°C的低功率應用中有用。
