Clarus XC 270

Clarus XC 270 3D screens use Harkness’ brand new 4th generation screen technology to provide a wide viewing angle, greater uniformity, improved colour and contrast both in 2D and polarised 3D.

Clarus XC 270 3D screens are designed for use in all cinema auditoria where 3D systems using polarised light are deployed. Whilst designed for 3D, the surface type also supports conventional 2D pictures giving a viewing experience similar to that of a conventional white screen.

d-smooth coating technology applied to the unique base material provides a visibly smoother surface finish and deeper visual perspective to 3D content.

Our proprietary and unique seam welding process ensures our screens have no visible seams under projection conditions.  Screens are available in either perforated or non perforated forms depending on speaker placement. Clarus XC 220 cannot be folded and must be rolled for transportation.

Acoustic Performance

Screens are perforated to facilitate the acoustic performance of behind-screen speakers.  For most cinema auditoria, standard perf pattern is used.  For close viewing (less than 5m/16ft), mini-perf pattern is recommended.


Non-perforated screens are available for use when there are no speakers situated behind the screen.

Screens should normally be transported and stored at temperatures between 5°C and 30°C (40°F and 85°F), with relative humidity less than 80%.
If screens are very cold (e.g. following air transport) then they must be allowed to warm up before unpacking, otherwise cold cracking may occur. Screens should be installed within a maximum of 2 months of shipping. Packages should be handled with care to avoid damage.

Care and Maintenance

The general environment where the screen is installed should be kept reasonably clean to avoid dirt and dust build-up. Screens can be periodically cleaned using a soft brush or cloth, doing this vertically with limited pressure. Screens can be cleaned using a damp cloth wetted with water and a mild detergent. Under no circumstances should screens be cleaned with abrasive materials or harsh chemicals such as acids, bleaches or solvents. Harkness Screens is not liable for damage caused to screens through the use of inappropriate cleaning methods or chemicals.
