May 13, 2014, Barrington, N.J. - Edmund Optics® (EO), the premier provider of optical components, introduces its new TECHSPEC® Hydrophobic Windows. These windows are ideal for use in harsh or humid environments for a wide variety of applications that would experience humidity or water exposure, including outdoor sights and scopes.

Resistant to liquid absorption or wetting

TECHSPEC Hydrophobic Windows are designed to resist liquid absorption or wetting, which simplifies handling and cleaning. The windows utilize a proprietary hydrophobic surface to cause the liquid to form droplets on contact, rather than be absorbed or spread across the surface of the window.

Anti-reflective coatings provide <0.4% reflection per surface

TECHSPEC Hydrophobic Windows feature anti-reflective coatings to provide less than 0.4% reflection per surface from 425-675 nm. The windows exhibit contact angles of greater than 107°. In order to minimize performance loss, TECHSPEC Hydrophobic Windows are designed to maintain contact angles of greater than 100°, even after moderate surface abrasion.

Seven models available with diameters from 5 mm-75 mm

TECHSPEC Hydrophobic Windows are available in seven models with diameters from 5 mm to 75 mm. All models are in-stock and available for immediate delivery for fast turnaround and excellent value.
