Standard Camera Detectors For Visible/NIR MTF Measurement Standard Camera Detectors For Visible/NIR MTF Measurement

Image Science offers Matrix digital camera detectors designed for real-time MTF measurements in the visible and near-infrared (NIR) wavelengths. Available in three models with variations in sensor size and pixel resolutions, these cameras can be used in a variety of applications.

SWIR MTF Testing Analyzers SWIR MTF Testing Analyzers

Image Science has developed two MTF analyzers for testing in the 1-3 micron region. They can be used as additions to an existing MTF measurement station, or can be delivered as a complete solution.  The first unit is a real-time device typically outfitted with an InGaAs camera that covers the 0.9 to 1.7 micron range. The second unit is a scanning system covering the 1.0 to 3.2 micron range. It uses a lead sulphide detector and sampling aperture.

Infrared Transmission System Infrared Transmission System

Image Science has developed a system for measuring the transmission of small IR lenses in the LWIR and MWIR wavebands. The infrared transmission system measures absolute transmission and minimizes the problems posed by testing short focal length lenses.

Matrix-SD MTF Starter Kit: MS1002/00 Matrix-SD MTF Starter Kit: MS1002/00

Image Science’s Matrix-SD MTF starter kit comprises an image analyzer and an object generator and is used for MTF testing in the spectral range of 350 to 1000 nm. It’s specifically been designed for individuals who already have an optical table/bench with standard positioning equipment.

Visible MTF System – Swinging Arm Type Visible MTF System – Swinging Arm Type

In a Swinging Arm system the lens under test and the image analyzer assembly are mounted together on a bench section which can be rotated in front of the collimated beam.  This configuration has the advantage that the field angle can be varied from one extreme to the other in a single continuous movement, which enables EFL and Distortion to be measured easily and accurately.

Infra-Red MTF System – Beam-Steering Type Infra-Red MTF System – Beam-Steering Type

The Infra-Red MTF System measures the Modulation Transfer Function (MTF) of thermal imaging lenses and telescopes, in both the 3-5 um and 8-12 um wavelength bands. In addition other optical parameters such as Effective Focal Length (EFL), Distortion, and Field Curvature may also be measured. A 1-3um (SWIR) detector is an available option. The bench can be programmed to perform high-speed production testing if required.

  • Theory And Measurement Of The Modulation Transfer Function (MTF)
    Theory And Measurement Of The Modulation Transfer Function (MTF)

    MTF is a quantitative and objective measure of the quality of an image formed by a lens or and electro-optical system. This measurement is appropriate for lenses of all qualities and can be calculated from lens design data, which enables theoretical and actual performances to be compared.

    Lens Manufacturers: Do You Know The Best Test For Lens Performance?

    A high-quality lens begins with a good design, tolerant to small manufacturing errors. The manufacturing process must be tightly controlled, from individual lens elements to final assembly. But, since small errors in manufacturing can result in serious loss of performance, end-of-line testing is necessary.

  • Infrared Transmission System Datasheet

    This datasheet includes an image of Image Science’s infrared transmission system and information on its features. This system measures the transmission of small IR lenses in the LWIR and MWIR waveband.

  • Modulation Transfer Function (MTF) Systems

    Modulation Transfer Function (MTF) Systems help system designers predict the actual image-forming capability of an optical system. These systems compensate for image degradation caused by inevitable aberrations and diffraction phenomena.

ABOUT IMAGE SCIENCE

Image Science was formed in 1991 and specialises in the design and manufacture lens testing systems for both Research & Development and production applications.  We concentrate on providing the best combination of accuracy, speed of measurement,  and ease of use.

In particular, we specialise in the measurement of MTF (Modulation Transfer Function) which is the most widely used measure of image quality. However, in addition to MTF, we also measure a wide range of other optical parameters, including:

  • PTF – Phase Transfer Function
  • EFL – Effective Focal Length
  • FFL – Flange Focal Length
  • Distortion
  • Field Curvature
  • Astigmatism
  • Strehl Ratio
  • Encircled Energy and Blur Spot Diameter
  • Absolute and Relative Transmission

Our systems are available for the following regions of the spectrum:

  • Visible
  • NIR (Near Infra-Red)
  • SWIR (Short-Wave Infra-Red)
  • MWIR (Medium-Wave Infra-Red)
  • LWIR (Long-Wave Infra-Red)
  • UV (Ultra-Violet)

Each one of our systems is configured to suit the customer’s particular requirements, and is supplied in a modular form which allows for later upgrading. Systems are often motorised, and can be programmed to perform automatic testing for high-volume production testing if that is required.

Our systems have been installed all over the world, and our customers include small and large companies, defence contractors, and government agencies.
