# 瞭解光學規格

## 製造規格

### 定心

##### 圖 2： 共軸測試

(1)$$\delta = \frac{\Delta}{f}$$

(2)$$W = \frac{\delta}{ \left( n - 1 \right)}$$

### 斜邊

##### 圖 4： 光學透鏡上的斜邊

3.00mm – 5.00mm 0.1mm
5.01mm – 25.4mm 0.25mm
25.41mm – 50.00mm 0.3mm
50.01mm – 75.00mm 0.4mm

### 通光孔徑

##### 圖 5： 以圖形顯示濾光片的通光孔徑及直徑

3.00mm – 10.00mm 90% 直徑
10.01mm - 50.00mm 直徑 – 1mm
≥ 50.01mm 直徑 – 1.5mm

## 表面規格

### 屈光度

##### 圖 6： 比較參考表面或使用干涉儀以測試屈光度誤差。

(3)$$\text{Power Error} \left[ \text{waves or } \lambda \right] = \frac{\Delta \, R \, D^2 }{8 \, R^2 \, \lambda}$$

## 材料規格
