Low Cost Dispersion Strengthened Ferritic Steels

Not Available Exciton proposes new dyes for laser eye protection for both the Notch and Tri-Stim approaches. Exciton's simulations and experiments support the synthesis of dyes with FWHM values of 4 nm. This value is one-half to one-fifth that previously observed. This value is also substantially less than the FWHM of reflection bands of rugates, holograms, or layered dielectrics because of the bandwidth requirements placed on such reflective technologies by the dimensions of the eye box. These new absorber dyes will also have absorption coefficients 2-5 times greater than those of current absorbers; therefore, proportionally lower dye concentrations will be required. As a result, processing and compatibility issues should be reduced and dye/host systems should demonstrate either a decrease in, or the absence of, interference from short wavelength bands. These dyes can be applied to both in-band and out-of-band solutions. Finally, eye protection incorporating these unusually narrow absorbers will have substantially less impact on color perception than either reflection or previous absorber technologies. Color balance may be within the human perceptual system's own adaptation range, or may be supplemented with only minor amounts of additional absorbers for critical color balance applications.
