Our filters & optical coatings solutions
If you need to trim your transmission wavelenghts or polarization, increase of reduce the reflection of your optics we have the right solution for you.
- Optical filters are usually used to reduce the amount of light either in a quantitative or qualitative way. They can either be made of colored glass of by multi-layer optical coatings.
- Multi-layer optical coatings can also be used to increase transmission (by reducing reflection) or for high reflection coatings.
- Coatings may also impact non optical properties :
- Hardness : DLC (Diamond like coatings)
- Shielding from electro-magnetic fields : ITO or other metalization
- Reflective coatings (Gold, Silver or protected alumunium mirror coating)
OUR COATING CAPABILITIES
SINOPTIX can propose coated parts on roughly every kind of material and shape.
OUR COATING SOLUTIONS
|TYPE OF COATING
|T up to 95%
|Ar, Au, Al, Mg coating

|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)
|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
|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.
Don’t hesitate to contact us for more details.
SINOPTIX offers wide solutions of optical filters &. Please browse below for some examples of our realizations.
