Custom coatings
We can create almost any custom coating, from basic AR coatings to complex or specialist coatings, such as oleophobic and hydrophobic coatings. The most common coatings are listed below.
| AR COATINGS V-AR coatings are designed for narrow band use. R type. › 0.2%. Broadband AR coatings tend to have higher reflectances the broader the wavelength range. R typ. for visible ‹ 0.4%. | MIRROR COATINGS Metal coatings are versatile and economical. Typical materials include aluminium, gold and silver. Dielectric coatings are normally more costly but offer better performance and durability. |
| BEAMSPLITTER COATINGS Beamsplitter coatings are designed to either be as non-polarising as possible or to distinguish between the two polarisations. | FILTER COATINGSDichroic coatings are all-dielectric and divide a beam spectrally. They are normally designed for 0º or 45º use. For stronger blocking, an interference filter can be used (see custom filters section below). |

Custom mechanics
An experimental optical system benefits most from the flexibility and economy of stock mounting systems, such as TubeMount. For serial production, however, an optical system usually needs to be much more compact, more simple to assemble and more economical when produced in volume. This usually requires a custom optomechanical mounting assembly.
Mechanical mounting systems are usually manufactured from aluminium and often black-anodised to reduce stray light reflections. We have extensive experience in creating such custom mechanical parts.
