    Laser high reflection film 369nm,395nm,1064nm

    1. the product introduction

    Kingki offers three high-reflection films.

    1, metal reflective film

    2, all dielectric reflective film

    3. Metal + dielectric reflective film combining the two

    The 369nm, 395 nm, 795 nm and 1064 nm laser high reflection films are all electrolyte reflective films.

    The all-dielectric reflective film is based on multi-beam interference. In contrast to antireflection coatings, the optical surface is coated with a film having a higher refractive index than the matrix material to increase the reflectivity of the optical surface. The multilayer reflective film is formed by alternately vapor-depositing two materials of high and low refractive index, and the optical thickness of each film is one quarter of a certain wavelength. Under this condition, the reflected light vectors on the faces of the superimposed layers have the same vibration direction. The composite amplitude increases as the number of layers of the film increases

    opening of the end of the high-index locus as the value of g decreases from

    1.0 partially compensates for the shortening of the low-index locus. A simi- lar effect exists as g increases from 1.0, when the lengthening of the low-in- dex locus is compensated by an overlapping with the high-index locus. The half-wave layer must be of an index higher than that of the substrate; oth- erwise, the opening of the half-wave circle would pull the low-index locus even farther from the point g = 1.0, hence increasing the reflectance further and effectively narrowing the characteristic. The important feature of the arrangement is that at the reference wavelength, the second quarter-wave portion of the half-wave layer and the following quarter-wave layer should have loci on the same side of the real axis.
