Laser Safety Information: Our CL Series Fiber Scope is equipped with an attenuating, laser safety filter to reduce the risks of accidental viewing of active fiber emissions. Since many of the wavelengths of light used in the fiber optic industry are not seen to the bare eye, the natural aversion reflect to viewing bright light is suppressed resulting in the potential for long periods of accidental exposure which can lead to permanent damager. The filter we install will provide over 35dBm of attenuation at wavelengths from1310nm to 1550nm. In addition,it will provide over 20.5dBm of attenuation at 850nm. However, it should be stressed that in spite of the protection offered, under no circumstances should an actively emitting fiber be viewed with a visual inspection scope such as this. Operation Step: Input the fiber which will be checked into the fiber insert entrance, insert another fiber connector into the light source entrance. See from the eyepiece and press the ON/OFF LED switch (Illumination). Adjust the focus control, just to find the clearest viewing.
