G&H | Phoenix
Finished Optics
G&H | Phoenix is located within a Technology Park in North Wales that is widely recognised in the UK as a centre for excellence in optics. We have over 10 tonnes of optical glass in stock (i.e. Schott, Ohara, CDGM, etc.), resulting in faster lead times on glass components.
Our optical components are used in many applications across the world which include:
- Night vision equipment and HHTI
- Surveillance and security cameras
- Radar, mapping and tracking devices
- Space optics assembly programmes
- Laser and cutting equipment
- Test and measurement equipment
- UAVs, periscopes / telescopes for military and non military
- Gimbals
- Target acquisition
- Protective windows over optical systems (for all manner of component designed for military aircraft / sea vessels and land vehicles)
- R&D projects for scientific research, lab work and specialised optical designs
- Custom made optics in IR materials including Chalcogenide, ZnS, ZnSe, Ge, CaF2 and Si
- Diamond turned product range includes IR diffractive hybrid and aspheric lenses
- Lens sizes from 8mm to 350mm
- Full in-house test capability
- State of the art, diamond turning laser machine for silicon parts
- Prototype optics as well as programme batch quantities
