UVIR-cut Filter
- Can be used as an optical filter to adjust color temperature and density.
- By applying various coatings to various substrates, a variety of optical properties can be realized, either by the substrate alone or by combining multiple substrates.
Applications
- Digital Camera
- Digital Camera for Broadcast / Cinema
IR-cut Filter
Features
- Three types are available for different purposes, including the IR-cut coating type, the IR absorbing glass type, and the hybrid type combining IR absorbing glass and IR-cut coating.
- We can also accommodate combinations with UV absorbing glass and UVIR-cut.
- Other special coatings include low-incident-angle-dependent AR coating, which improves the incident angle dependence of the coating, low stress AR coating, which enables deposition of thin substrates of less than 0.2 mm with minimal warpage, and other coatings with conductive film and water repellent film functions.
