OptiLayer:  Your Partner in Design and Post-Production Characterization of Optical Coatings

 

Simple color targets

OptiLayer provides Color Design options enabling design of multilayers with specified color properties. In order to design such coatings, Color Targets are to be specified. OptiLayer allows one to specify up to 99 color targets. Each target contains:

  • Type of color characteristic (according to selected Color Space)
  • Angle of incidence
  • Spectral Characteristic (reflectance, transmittance and/or back side reflectance)
  • Polarization type (S, P and A-averaged)
  • Values of color coordinates
  • Tolerances
  • Qualifiers (for Range Targets)

Convenient Preview Option allows one to visualize specified color targets.

Example. Color Targets for a multilayer reflecting light of yellow and blue colors from its front and back sides. The coating transmits white light. (To see how Preview option works, put the mouse over the picture)

Combined targets

OptiLayer allows one to specify complicated targets combining conventional target, color target and integral target. For example, if someone wants to design an anti-reflection coating reflecting bluish and greenish colors.

As a result of Needle Optimization procedure, 8-layer anti-reflection coating reflecting bluish and greenish light is obtained. (In order to see design process, put the mouse button on the right hand side picture)

 Design with Range Color Targets

 

Color Range Targets are specialized targets described by a convex polygon. Range Color targets are available for Chromaticity, CIE YU'V' 1976, CIE YU'V' 1960, Hunter Lab, CIE L*a*b*, CIE L*ru*v* color spaces only.

If a point in the selected color space is inside a polygon of the Color Range target, the corresponding term in the Merit function is zero. If the point is outside the polygon, the corresponding term in the Merit function is computed as a squared distance from the point to the boundary of this convex polygon, as show below.
