Capabilities

Thin Film Coatings Highlighted Product VLOC routinely applies high power laser damage threshold coatings ranging from 250nm in the ultraviolet and extending up to 2300nm in the near infrared. Thin film coatings may be processed on a quick turn around basis on a variety of optical substrates and crystals. Environmental testing and spectral scans are provided as required .

VLOC utilizes automated cleaning and coating processes. Our coating facility is equipped with modern state of the art automated box coaters equipped with cryopumped systems, multiple pocket electron beam sources (E-beam) and ion beam sources for both ion assisted (IAD) and ion beam sputter (IBS) deposition. Along with our environmentally controlled clean room, we offer several coating technologies which provide the ultimate in damage resistance and physical durability. Film deposition is controlled by both quartz crystal and optical monitoring techniques.

Polarization

Optical interference coatings used at other than normal incidence respond differently to s and p polarized light. The difference in reflectance between s and p polarizations of a 50% beamsplitter can be as high as 35%. For this reason, it is essential to specify s, p or random (the average of the s and p performance) polarization whenever the angle of incidence exceeds 20 degrees. The s and p polarization are defined by the relationship between the plane of polarization and the plane of incidence. A coated optic exhibits its s polarized performance when the polarization direction of the input beam is perpendicular to the plane of incidence. The same optic exhibits p polarized performance when the input beam polarization lies in, or parallel to, the plane of incidence. Since s and p polarization are determined with reference to the geometry of incidence on the optic, simply stating "horizontal" or "vertical" polarization is not sufficient.

Testing

Transmission and reflection testing is performed with a Perkin-Elmer Lambda 19 UV/VIS/NIR or Cary 5 spectrophotometer, calibrated by comparison to NIST standard reference materials. Bidirectional Scattering Distribution Function (BSDF) and surface roughness are measured with a TMA Microscan scatterometer. Environmental testing capabilities include standard MIL-SPEC durability tests and a large capacity Blue-M humidity chamber.

OPTICAL FABRICATION: Thin films provide wide-angle correction for waveplate components
An alternate approach to traditional stretched-polymer or quartz waveplates introduces a C-plate (or out-of-plane) retardance in combination with hybrid-liquid-crystal polymer A-plate technology for a flat retardance response.

Thin-film coatings form 10-km-radius surfaces
Although gravitational waves-ripples in the space-time continuum due to moving matter-have never been detected, the Large Scale Cryogenic Gravitational Wave Telescope (LCGT; Honshu, ­Japan) and the Advanced Laser Interferometric Gravitational Wave Observatory (LIGO; Hanford, WA, and Livingston Parish, LA) are just a few of the interferometric systems actively looking for them.
