LensCheck™ Quality Control

Optikos CorporationRequest Info
 
Optikos' LensCheck Quality ControlOptikos, the leader in image quality test equipment, is pleased to offer this compact, efficient, easy-to-use quality control tool. The LensCheck™ Instrument is a cost-effective solution to your production and prototype lens qualification needs, and provides portable and precise measurements for VIS/NIR through LWIR applications.

With patented Optikos®VideoMTF image analysis software, LensCheck instruments feature real-time MTF testing and analysis that allow manufacturers to qualify incoming products quickly and reliably—helping meet quality assurance standards for complete assemblies.

The LensCheck’s configurable automated measurement routines and industry-leading accuracy make it the instrument of choice in production and R&D facilities around the world. Optikos validates all measurements with a 50mm F/5 Audit Lens:

VIS—better than 2% (1% typical); and repeatability—better than1% (0.5% typical) LWIR—better than 3% (2% typical) to 40 lp/mm; and repeatability—better than 2% (1% typical)

Its flexible platform allows a wide range of measurements, including:

   •  MTF – on/off axis
   •  EFL and f-number
   •  Back focal length
   •  Astigmatism
   •  Field Curvature
   •  Distortion
   •  Transmission (VIS optional)
   •  Stray light (VIS optional)

A range of options that enhance the LensCheck’s flexibility include:

   •  Rotary Lens Mount (VIS and LWIR)
   •  Audit Lenses (VIS and LWIR)
   •  Reference Lenses (VIS and LWIR)
   •  Transmission Kit / Relative Illumination Kit (VIS only)
   •  Stray Light Kit (VIS only)
   •  Finite Conjugate Instrument (VIS only)
      --available as an option or standalone unit)
   •  Reflective Collimator (VIS and LWIR)
   •  Line of Sight (Rotary Lens Mount) (VIS and LWIR)
   •  Achromatic Objectives (VIS only)
   •  Apochromatic Objectives (VIS only)
   •  Lens Mounts (VIS and LWIR)

Optikos provides innovative applications of optical technology to a range of government, commercial, and consumer products organizations worldwide. For defense applications, Optikos is a DDTC registrant and has facility clearance and extensive experience with products and services regulated by the ITAR. Known internationally for its engineering excellence, Optikos Corporation’s commitment to meeting and exceeding the expectations of its customers is exemplified by its long-standing ISO 9001 certification.

GLOSSARY
metrology
The science of measurement, particularly of lengths and angles.
image quality
A measure of the closeness with which an optical image is capable of resembling the original object. The factors that affect image quality are lens aberrations, diffraction, dirt and stray light within the system, and atmospheric turbulence and haze outside it. If the image is recorded photographically, it can become further degraded by image motion during exposure and by light diffusion in the emulsion. At one time image quality was expressed by its resolving power, but today a more meaningful...
astigmatism
A lens aberration that results in the tangential and sagittal image planes being separated axially.  
distortion
A general term referring to the situation in which an image is not a true-to-scale reproduction of an object. The term also is used to connote the temporal alteration of the signal's waveform shape. There are many types of distortion. See also anamorphic distortion; curvilinear distortion; keystone distortion; panoramic distortion; perspective distortion; radial distortion; stereoscopic distortion; tangential distortion; wide-angle distortion.
illumination
The general term for the application of light to a subject. It should not be used in place of the specific quantity illuminance.
