SafetyScan Full Stepped Lens

The Pangolin Safety Scan Lens (Full Stepped) is a patented diverging lens for laser projectors that increases beam divergence across the entire projection area to enable safer, more powerful, and more visually stunning audience scanning shows.

From the Manufacturer

Laser safety is important, and as a professional laserist, you should be careful when projecting laser beams into an audience. This is why Pangolin developed the Safety Scan Lens. Our patented Safety Scan Lenses were designed to help make your shows safer, while at the same time allowing your shows to maintain a high level of visual impact.

When audience scanning shows are performed using a raw laser beam, that beam is typically so small that the entire beam's power can enter a viewer's eye. The SafetyScan lens increases the divergence of the laser beam throughout the full projection area. Once affected by the SafetyScan lens, the beam becomes bigger — and because the beam is bigger, this effectively lowers the irradiance (beam power per unit area) that enters the pupils of audience members. Due to the inverse-square law that governs light, this means that higher actual laser power can be used, because the size of the beam is increased in both the horizontal and vertical dimensions.

The result is a show that can be more powerful, safer, and much more pleasant to view — with a softer, more immersive audience scanning experience. The full stepped lens diverges beams across the entire scan area, making it ideal for applications where the full projection field — including both audience-level and aerial beams — benefits from increased divergence.

Features

• Full stepped lens design — diverges beams across the entire projection area for comprehensive beam divergence coverage
• Increases laser beam divergence in both horizontal and vertical dimensions, lowering irradiance throughout the projection field
• Allows use of higher actual laser power while maintaining safer irradiance levels for audience scanning
• Available in six diopter strengths (-1 through -6) to match a wide range of projector beam divergence and venue distances
• Compatible with projectors using the Kvant lens mount or custom-built mounting arrangements with three-axis adjustment
• Can be mounted externally in front of the exit aperture or internally inside the projector for added security
• Simple and reliable "binary" operation — the beam is either affected or it isn't, with no intermediate states
• Divergence tables provided for lasers with M² of 1.2, 3.0, and 5.0 to assist in proper lens selection
• Protected under US Patent numbers 8,506,087 and 8,681,828
• Recommended use: Audience scanning laser shows, live events, concerts, festivals, nightclubs, theatrical productions
