Inspec.x L 5.6/105

High-Resolution Lenses for Line-Scan Applications

This series was developed to meet the highest demands in the field of industrial image processing with very large sensors. The lenses of the Inspec.x L5.6/105 series are characterized by their outstanding imaging performance over an image circle of up to 82 mm. The very popular 12 k/5 µm and 16 k/5 µm line scan sensors as well as very large area sensors benefit from the high resolution, low distortion and excellent color correction of the objective lens.

The V-groove interface on both ends of the lens enables the best azimuth position to be set and the lens to be used in the retro position for magnifications up to 3×.

  • Large image circle up to 82 mm
  • Perfect match with 5 µm pixel size
  • Full-metal barrel
  • Lockable aperture
  • Focal length: 105 mm
  • Aperture: 5.6–11
  • Working distance: 100–420 mm

Inspec.x L float

High-Resolution Lenses with Wide Magnification Range

These lenses combine a newly developed mechanism with the proven imaging performance of the Inspec.x L series. One lens covers a particularly large scale range.

By using a floating element lens, these lenses achieve a very high optical performance over the extremely large scale range from 0.3× to 3.0× or from 0.06× to 0.52×. Thanks to the mechanical full metal design, it can also be used in the industrial sector, with the gear rims providing the option of automation.

  • Ideal for 12k und 16k sensors
  • Geared rings for focus and aperture
  • Large image circle up to 82 mm
  • Extreme magnification range
  • Floating element optics
  • Perfect match with 5 µm pixel size
  • Spectral range: 400–750 nm
  • Distortion:: < 0,4 %

Inspec.x L 4/105

High-Resolution Lenses for High Magnification Imaging

The development of this lens series enables object resolutions down to 2 µm. The lenses are optimized to achieve a resolution of up to 200 Lp/mm in the object plane when using sensors up to 82 mm in length. This high image quality is achieved across the entire image circle. In addition, the extremely low distortion below 1 µm over the entire field of view stands out.

The lenses of the Inspec.x L 4.0/105 series harmonize perfectly with modern high-resolution cameras with 12 k/5 µm and 16 k/5 µm sensors and are therefore ideal for applications that require extremely high resolution. There are three lenses available, optimized according to the image scale, each of which can also be ordered in a special version that is optimized for use with a prism beamsplitter (coaxial illumination).

  • Outstanding MTF performance over the entire image circle
  • Diffraction-limited optical design
  • High numerical aperture
  • Focal length: 105 mm
  • Image circle: up to 82 mm
  • Spectral range: 400–750 nm
  • Iris diaphragm: manual, lockable
  • Mount: V-groove
  • Wide range of mechanical accessories

Inspec.x L 4/60

High-Resolution Lenses for small Magnifications

The lenses of this series are optimized for the imaging of objects at infinity up to a scale of 0.2 ×. Here they show an extraordinary contrast for sensor sizes up to 70 mm diagonal. In addition to this high contrast, the lenses are characterized by very good color correction and minimal distortion. The 60 mm lens has an unusually high performance for this short focal length and thus enables the imaging of large objects in spatially limited applications with large sensors.

With their screw-on thread, the lenses can be used with the popular Modular Focus helical mount. This enables the lenses to be adapted to virtually all existing cameras using various camera adapters.

  • High contrast for small magnifications
  • Excellent color correction
  • Magnification range: 0 – −0.2
  • Image circle: up to 70 
  • Spectral range: 400–750 nm
  • Iris diaphragm: manual, continuous with set screw
  • Mount: compatible to Modular Focus
  • Wide range of mechanical accessories
