Phase One Industrial has expanded its RS and RSM lens offering with three new high performance lenses for high-altitude aerial photography and long-range aerial and ground inspection applications.

The 300mm AF, 180mm, and 150mm MK II lenses are designed to enhance the performance and flexibility of Phase One Industrial’s iXM-RS and iXM aerial camera series. Each offers precision imagery, taking advantage of the cameras’ ultra-high resolution backside-illuminated (BSI) CMOS sensors, to maintain a smaller ground sample distance (GSD) while flying at higher altitudes, the company said.

Phase One RSM 300mmAF. With the longest focal length in the line-up, this lens offers a 5 cm GSD from 13,000 feet. It fits both iXM and iXM-RS camera models and produces superb image quality by enhancing the cameras’ ultra-high resolution BSI CMOS sensors (3.76 µm pixels).

The lens is designed for both high-altitude 2D and 3D mapping and long-range ground inspection. The motorized lens offers a focus range of 10 m to infinity within which a predefined distance can be set remotely. A self-locking mechanism is built in to secure the focus position against vibrations.

• 5 cm GSD from 13,000 feet
• 10 m to infinity focusing range
• f/8 – f/32 aperture range
• 1/2000 sec exposure time
• RS Shutter reliability – 500,000 actuations

Rodenstock RS 180mm. Specified by Phase One and built by Rodenstock Photo Optics, Germany, this lens reaches a 5 cm GSD from 8,000 feet when used with the iXM-RS150F camera. The lens supports the camera’s ultra-high resolution BSI sensor for greater image quality and is integrated with a Phase One RS reliance shutter for speed and reliability. The RS 180mm enhances high-altitude aerial 2D and 3D mapping and improves efficiency in oblique configurations.

• 5 cm GSD from 8,000 feet
• f/6.3 – f/22 aperture range
• 1/2000 sec exposure time
• RS Shutter reliability – 500,000 actuations

Phase One RS 150mm MK II. A 5 cm GSD from 6,500 feet is achievable with the RS 150mm MK II lens. It complements the iXM-RS150F camera’s ultra-high 150-megapixel resolution BSI CMOS sensor for acquiring quality images for high-altitude aerial 2D and 3D mapping.

• 5 cm GSD from 6,500 feet
• f/5.6 – f/22 aperture range
• 1/2500 sec exposure time
• RS Shutter reliability – 500,000 actuations

Every Phase One Industrial lens is rigidly built for robustness against vibrations and shocks to meet RTCA DO160G standards, and is individually tested for performance and high-modulation across the whole image area.
