Large Format Lenses

 

Raptar Pro Lens

The Raptar Pro large format lens series has been specifically designed for the line-scan and large area sensor market. The first lens in the series is the 1X Raptar Pro 86 mm. With its improved MTF, strong relative illumination and zero distortion over a 90 mm field of view, this lens is ready for challenging applications. Navitar Raptar Pro Lenses

  • Covers up to 90 mm sensors.
  • Manual iris.
  • Covers up to 90 mm FOV.
  • High resolution - 100 lp/mm.
  • Less than 0.1% distortion.
  • F/4.0 design.
  • Sized for 12K line sensors.
  • Optimized for 95 mm WD.
  • Ideal for electronics inspection, web inspection, flat panel inspection (LCD and plasma), biomedical imaging, factory automation, food and beverage inspection and more.

Mechanically, the lens is designed with a T-mount rear coupler and is available with the adapters that convert to a C, F, or SLR format. An optional clamp can be attached to the exterior of the T mount for mounting to a flat surface. A special rear coupler is available for Dalsa 12K cameras. Dimensions of the parent lens are provided for customer coupling of other special configurations. The rear dovetail interface of the lens provides a means of rotating a line-scan camera to the maximum performance axis of the lens. Click here for a complete system diagram.

Additionally, to accommodate the new larger format cameras with the larger non-standard threads, an M72 x 0.75t mounting system is available. For those cameras with a thread smaller than M72, a “step-up” ring must be used. These rings may be found at www.photofilter.com. There are two varieties of M72 mounts with flange distances of 6.56 and 30.8mm. Any user fabricated custom mount must maintain these distances for the Raptar Pro to perform satisfactorily. A special rear coupler is available for Dalsa 12K Piranha series cameras. The rear dovetail interface provides a means of rotating a line scan camera to the maximum performance axis of the lens.

The Raptar Pro lens can be used for inspection and viewing of objects in numerous applications including machine vision, Q/C inspection, web inspection, biomedical imaging, product manufacturing, and more.
