以往的凹面光柵系統只能開小角度入射至光柵表面，如果將角度變大，會有許多能量沒有覆蓋到光柵上，為了將這些能量收集起來，設計了一凹面鏡，將入射之大角度光源，經由此面鏡，匯聚起來，反射成一平行光入射至光柵，在解析度近似相同的條件下，首先將探討有無加反射式凹面鏡系統光能量增加的效率，再將這兩系統加上波導比較能量的差異。
最後將有反射式凹面鏡系統拿出來討論，此系統波導距離理想聚焦點之強度分析與解析度探討，與此系統偵測器大小之強度分析與解析度探討。

In the past, a concave grating system of incident light is limited due to its narrow acceptance angle. If the acceptance angle becomes large, there will be a lot of energy out of concave grating. In order to collect energy, we designed a concave mirror. By adding a concave mirror, we are able to increase the light acceptance angle. Under the same condition of the resolution, the study shows the light intensity such a concave system with mirror as compared to a single concave system, and then compared the light intensity of the two systems with waveguide.
Finally, the study choose a concave system with mirror and waveguide. We study the effects of the distance of ideal focal line and different detector sizes on the resolution and the light efficiency.
