LBS-100 Attenuator

LBS-100 Attenuator

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

In addition to the stackable filters and beam splitters described above, one can purchase the LBS-100 system that is not as compact as the stackable system above but has larger aperture, can be changed without disassembly 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 insure no distortion of the beam.

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...
