LBS-100 Attenuator

LBS-100 Attenuator

Combination Neutral Density Filters and Single Beam Sampling Optic System, Lasers Up To ~400W

The LBS-100 system that is not as compact as the LBS-300s above but has
larger aperture, and has versions for longer wavelengths. The system contains
the mounting frame, 1 wedge beam splitter and several attenuators. The exit end
of the LBS-100 is standard C mount thread so all our cameras can be mounted
to the frame. The wedge angle is 6.5 degrees to insure that the reflection from
the rear side will not enter the camera. The optical elements are flat to 1/4 wave
in the visible to ensure no distortion of the beam.

What should be my Safety concerns while using LBS-100?

Regular laser safety precautions should apply. Please note, that the main incident beam will exit the LBS-100, refracted approximately 6.5°. Provision must be made to safely contain the transmitted beam by beam dump or power meter.

Can I use LBS-100 both for beam profiling and power measuring?

Yes, the main function of LBS-100 beam splitter is Beam profiling, however it allows simultaneous measurement of a beam transmitted thru wedge by power meter.

Imaging UV light with CCD Cameras

Is it possible to image a UV laser with a Silicon Sensor CCD camera offered by Ophir-Spiricon? The answer is yes, but the direct UV light ablates Silicon CCD chips over time. The ablation is cumulative and depends on the intensity, the wavelength, and the duration of the light on the sensor. The best choice for imaging UV light without damage is to avoid directly imaging the beam on the CCD sensor by using an UV image converter... Read more...
