AEROSPACE & AVIATION MOLDED OPTICAL GLASS DOME - FLANGED

In addition to stringent optical requirements (see Optical Camera Domes), flange mounted optical molded glass domes for UAV and RPV aviation applications fall into a unique category of mechanical demands. In particular, the faster the aircraft, the more challenging the demands on the mechanical integrity and optical performance of an aviation camera dome due to impacts. For aerospace applications, including missiles and UAVs, the biggest challenge comes from low altitude flight operations. Although the more infamous bird impacts are a concern and must be considered, the biggest problem comes from abradants such as sand, dirt and even bugs!

This is especially prevalent in arid and semi-arid areas of the world, which contain high concentrations of airborne particulates and bugs. Be it aviation border patrols on the U.S/Mexican border, or low altitude UAV / RPV flight operations in the Middle East, airborne particulates must be considered when designing an aviation optical glass dome. Ignoring this critical environmental hazard will result in loss of optical performance of aerospace camera domes, sometimes in a matter of only days or weeks. Rayotek specializes in engineering and manufacturing flanged mounted molded glass domes specifically for aerospace applications.

WHAT IS THE BEST OPTICAL DOME MATERIAL FOR AEROSPACE APPLICATIONS?

Choosing the right material is critical in engineering an optical glass dome for UAV, RPV and Missile applications. Highly durable materials such as sapphire and ALON are the most robust and abrasion resistant, but material costs are considerably higher than glass, plus sapphire and ALON cannot be molded. Sapphire and ALON must be grown, ground and polished; all very time consuming processes. In many applications Rayotek recommends borosilicate glass, or, for small optical domes, chemically-strengthened specialty glasses such as Gorilla® Glass*. These high quality optical glasses are more than adequate and can be molded, making manufacturing times literally thousands of times faster than processing sapphire type materials.

PROPERLY MOUNTED GLASS DOMES PERFORM BETTER, LAST LONGER:

Aerospace glass domes are highly dependent on proper mounting systems for the best strength and reliability. Proper mounting will also reduce vibration, which can impact optical and sensor performance with sensitive systems. Rayotek engineering focuses on the entire dome assembly including the seal, material compatibility and the flange, not just the glass dome. Rayotek has over 25 years of research, engineering, and in depth testing, to develop light-weight flanged dome mounting systems. This type of mounting system allows glass domes to achieve optimum strength and optical performance with minimal mass increase due to the flange.
