滤光片

There are yellow filters (for use under hazy weather conditions) attached to the inner side of the ocular-cover. The eyecups are made of soft rubber and fold in so that the binocular can be used with gas-mask.

它的特征如下：有极其强壮和沉重的身躯，可用电池能源照明的刻度板和主动红外光源探测器，物镜盖内有黄色滤光片，软橡胶制成的目镜罩在戴眼镜使用时可被翻折。

The correct shade of filter plate needs to be used to prevent exposure.

需要选用正确的滤光片来防止曝光。

It can also used in other harmful gas online remote measurement system by use different light filter.

通过更换检测装置中的滤光片，可以实现其它有害气体的在线监测。

Moreover, by appending filter and interference light filter, the signal noise ratio of the system is enhanced greatly.

此外，还分析了检测光学系统，对信号中的噪声进行分析，在系统中增加了滤波装置和滤光片，大大提高了检测系统信噪比。

Face on the first glass prism element. The interference filter is formed by depositingtwo prism elements are joined together.

这个滤光片是在两个棱镜连接前由第二棱镜一面镀SiO2/TiO2复合层膜构成。

A dichroic interference filter is interposed between the two prism elements and is disposed at an angle of 221/2° to an input face on the first glass prism element.

将一块二向色干涉滤光片介入两个棱镜中，并使它倾向于第一面棱镜投入面的221°~222°角之间。

That's exactly the reason why some professional binoculars come with yellow filters to be attached to the oculars.

这也解释了为什么有些专业望远镜要附带接在目镜上的黄色滤光片。

Each ultraviolet light pipe with 8w254nm8w365nm has ultraviolet ray filter of 150mm×70mm square meters which could be use separately by shore wavelength of long wavelength or both.the largest feature of the appliance is all-sealing design,to be used at all times,low power consumptionlong-time using.

本仪器采用2支8w254nm 和2支8w365nm 的紫外灯管，紫外滤光片的面积为150mm×70mm ，使用时可单独使用短波波长或长波波长，或者同时使用两个波长，本仪器最大的特点是全封闭设计，可随开随用，电耗功率小。
