我們可以根據(jù)光類(lèi)型，波長(zhǎng)，OD選擇不同的
我們可以根據(jù)光類(lèi)型，波長(zhǎng)，OD選擇不同的。
選擇需要注意以下幾點(diǎn)
1. 需要進(jìn)行防護(hù)的激光器波長(zhǎng)范圍，
2. OD值，光密度Optical Density：OD值越大，對(duì)相應(yīng)波長(zhǎng)范圍防護(hù)能力越強(qiáng)，
3. VLT（可見(jiàn)光透過(guò)率）：VLT數(shù)值低于20%，需要在一定照明的環(huán)境中進(jìn)行使用。
4. Frame（指的是鏡框類(lèi)型）：面部輪廓等信息。
根據(jù)類(lèi)型區(qū)分：

根據(jù)波長(zhǎng)和OD類(lèi)型區(qū)分：
通過(guò)波長(zhǎng)和OD數(shù)值選擇防護(hù)眼鏡
關(guān)于OD值的說(shuō)明：
光密度（OD）[optical density]定義為材料遮光能力的表征。它用透光鏡測(cè)量,表示被檢測(cè)物吸收掉的光密度，是檢測(cè)方法里出現(xiàn)的專有名詞。
光密度沒(méi)有量綱單位，是一個(gè)對(duì)數(shù)值，光密度是入射光與透射光比值的對(duì)數(shù)或者說(shuō)是光線透過(guò)率倒數(shù)的對(duì)數(shù)。計(jì)算公式為OD=log10（入射光/透射光）或OD=log10（1/透光率）
| OD1 | 0.1 |
| OD2 | 0.01 |
| OD3 | 0.001 |
| OD4 | 0.0001 |
| OD5 | 0.00001 |
| OD6 | 0.00001 |
| OD7 | 0.000001 |
