The OPTITEST system is configurated from basic opto-mechanical components which are modular, compatible to each other and common to most of the instruments. The opto-mechanical components are specifically designed to allow instruments reconfiguration on site without any adjustments. The advantages of this modular approach are significant from point of view of flexibility and cost efficiency:
 
  • to adapt the instruments to new applications might be sufficient to buy some components only, avoiding the costly procurement of a complete new instrument.
  • setting up a modified instrument is easy and fast, since no adjustments are necessary.
  • the OPTITEST system is continuously developed, so that new components and features (e.g. image processing) enhance the utility of existing instruments.
     
    Tube mounted objective Lenses
     
    The tube mounted objective lenses represent one of the main components of OPTITEST Autocollimators, Collimators and Telscopes.
     
    Typical features of these basic elements are:
     
  • barrel made of hardened steel with hard chrome surface
  • front end surface accurately square to optical axis
  • front end surface with female thread M35x0.75 mm (for barrels D 38 mm) and M53x0.75 (for barrels D 57 mm) to allow addition of accessories (achromats in mount, beam deflecting mirrors atc.).
     
    Similarly with the instruments described before, the tube mounted objective lenses are available in two different types:
     
  • TUBE MOUNTED OBJECTIVE LENSES (Infinity Setting)
  • TUBE MOUNTED OBJECTIVE LENSES WITH FOCUSING DEVICE (Finite Distance Setting)
     
    Accessories

    Reticle Adapters
     
    A Reticle Adapter is basically an assembly containing:
     
  • one reticle in mount when designated for collimators and telescopes
  • a beamsplitter and two reticles in mount for use in autocollimators
  • mechanical interface for connection to tube mounted objective lenses (M35x0.75mm)
  • mechanical interface for connection with eyepieces and illumination devices (M27x0.5mm)
     
    Reticle Adapters for Collimators and Telescopes

     
    Reticle Adapter for Autocollimators
     
    The Beamsplitter Mount (BSP) contains a beamsplitter and two reticles in mount for use in autocollimators. The Beamsplitter Mounts with the eyepiece and illumination forms an assembly known as Autocollimation Head.

    Eyepieces
     
    The range of eyepieces included in the OPTITEST line provides capabilities for many applications requiring different parameters as:
     
  • large field of view
  • large magnification
  • facilities for attaching CCD-cameras, etc.
     
    All the eyepiece are focusable and have a long eyepoint which is convenient for spectacle lens wearers. A diopter scale can be used for various measurements like astigmatismus, flatness errors etc.

    CCD-Camera Adapter
     
    This device includes highly corrected imaging optics which transfer the reticle image from the eyepiece on CCD-array. The Camera Adapter has a mechanical interface to CCD-Camera (C-mount) and a threaded mount (M28x0.75) to eyepiece.
     
    The imaging optics are interchangeable (factory assembly). A complete Video Attachment includes:
     
  • CCD-Camera-Adapter
  • CCD-Camera (standardly 2/3"monochrome. On request other types)
  • TV-Monitor, monochrome, CCIR
  • BNC-Cable to connect camera and monitor
  • Power supply for camera

    Illumination Devices
     
    Standard Illumination
     
    The standard illumination device of OPTITEST normally includes:
     
  • condenser optics
  • a green filter with a ground side working as diffuser
  • illuminating lamp in socket
  • connection cable to power supply. Length 1m.
     
    The tube containing the filter is directly screwed on the illumination housing. The standard green filter can be easily exchanged if necessary.

    Further illuminations
     
    In some applications the light intensity of the standard illumination might not be sufficient. This is the case in procedures requiring autocollimation with a small (uncoated) reflector or long distances between reflector and autocollimator. A need for more light is also related to collimators with very long focal length or alignment of complex optical systems. For these or similar applications following illumination devices with halogen lamps are recommended.
