TiBlack™ Coating (UV, VIS, NIR)

Benefits

• Optical Black Coating
• High absorption in the UV, VIS and NIR range
• Low reflection in the UV, VIS and NIR range
• Can be patterned by lift-off and chemical etching
• Low defect and pin hole level
• Excellent environmental stability
• Good adhesion on glass and metal substrates
• RoHS conformity

Applications

TiBlack™ coating will mainly be used to reduce scattered light and for blackening. Examples are apertures in lense systems of endoscopes or sensor lids. Furthermore, in projection applications, digital imaging and for scientific solutions. In monolithic arrays of dichroic filters, TiBlack™ is used to cover the interspace between the individual filters resulting in minimized cross-talk and stray light.

• Multi-Bandpass Filters
• Endoscopy
• Space observation
• Sensor lids for cameras
• Multispectral Imaging
