詳細(xì)介紹

我們可以根據(jù)光類型，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（指的是鏡框類型）：面部輪廓等信息。

根據(jù)類型區(qū)分：

根據(jù)波長(zhǎng)和OD類型區(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
