Our coating capabilities
SINOPTIX can propose coated parts on roughly every kind of material and shape.
Our coating solutions
| Type of coating | Usage | Detail |
|---|---|---|
| Anti-reflect (AR) | improve transmission | T up to 95% |
| Mirror | Signal reflection | Ar, Au, Al, Mg coating |
| Bandpass filters | control a narrow, well defined spectral wavelength | width: 10nm |
| Bandstop filters / notch filers | reject light of a specified wavelength range | up to OD6 in the reject area |
| Shortpass & longpass filters | let the signal pass after or before a specific spectral value and stop the remaining | cut-on/off slope 3 to 5% |
| ND filters (Neutral Density) | Attenuate an optical signal | up to OD 8 (T=10^-8) |
| Dichroic filter | Split the signal in different wavelenghts | Trichroic are also available |
| Metallization coating, ITO (Indium TIn Oxyde) | Conductive channels (heat / electricity) & welding supports | metal mask tolerances +/- 0,1mm |
| Anti-sludge coating | Protect against dirt deposition | – |
| Water repellent coating | Avoid water deposition | – |
| DLC (Diamond Like Carbon) | Hardening for anti-scratch | – |
Color glass filters
Colored glass filters are material colored filter (in opposition with coated filters). They are cheaper and more resistant than coated filters, but their optical properties are less precise and hardly customized.
SINOPTIX proposes a wide range of colored glass filters of most famous brands (SCHOTT/ OHARA / CORNING) or their Chinese equivalents.
