Laser-Damage Attack Against Optical Attenuators in Quantum Key Distribution
WebThe strength of attenuation is often quantified as an absorbance or optical density, which is the absolute value of the logarithm of base 10 of the power transmission factor. For example, an optical density of 3 means an attenuation of optical powers by the factor 10 3 = 1000. Absorbing and Reflective Neutral Density Filters WebThe Ophir® LBS-300HP-NIR beam splitter for high power NIR lasers is a compact device that can deliver extremely high power density attenuation, up to 15MW/cm2 at 5kW. It reflects less than 0.0001% of the incident NIR beam while transmitting 99.9999%. This enables measurement of beam shape, focal spot, beam waist, and overall power.
