AEROSPACE AND DEEP SEA:
Where harsh environments and demanding requirements leave no room for error, the exceptional performance, durability, stability and reliability of CEO OPTICS products provide the system builder an extra safety margin. That’s why we’ve become a favored supplier to leading developers of advanced targeting systems, IR countermeasures, directed energy weapons, heads up displays and laser communication systems, as well as navigational systems for civilian aviation and space-based instruments.
Most short range air-air missiles, and even some medium-range missiles use some variant of infrared guidance, homing in on heat differentials produced by a target’s exhaust or even just air friction against its surface. The IR sensors are mounted in the nose of the missile, and if you look closely you’ll see that they’re behind a transparent “dome.” Creating those domes is a challenging materials task: give us something that lets as much IR radiation as possible in without distortion, but protects everything inside the missile from the buffeting and heat created during the missile’s own Mach 3+ flight and violent turns.
The hemisphere dome we manufactured be used to protect the lens of underwater camera, which could resist the pressure of water, and give a best view field to catch picture.
Specification of hemispherical dome we could supplied as follow:
Materials: BK7 glass, fused silica Pyrex(borosilicate) various types of optical glass.
Diameter: From 10 to 250 mm.
Diameter Tolerance: 0.1 mm, standard; 0.01 mm – attainable.
Surface Quality: 60/40 Scratch/Dig, standard; 20/10 Scratch/Dig, attainable depending on material type and combination of other parameters.
Power/Irregularity: 5/1 (interference fringes), standard; 0.5/0.1 (interference fringes) depending on material type and combination of other parameters. Aperture 60 deg.
Decentration: 0.05mm, standard; 0.01, attainable.
Optical dome lens is a transmisive optical device that affects the focus of a light beam through refraction.
