Tube mounted objective lenses
The tube mounted objective lenses represent one of the main components of OPTITEST Auto-collimators, Collimators and Telescopes. Typical features of these basic elements are:
Similarly with the instruments described before, the tube mounted objective lenses are available in two different types:
A Reticle Adapter is basically an assembly containing:
Reticle Adapter for Collimators and Telescopes
Reticle Adapter for Auto-collimator Beamsplitter Mounts
The Beamsplitter Mount (BSP) contains a beamsplitter and two reticles in mount for use in auto-collimators. The Beamsplitter Mounts with the eyepiece and illumination forms an assembly known as Auto-collimation Head.
The range of eyepieces included in the OPTITEST line provides capabilities for many applications requiring different parameters as :
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.
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:
The standard illumination device of OPTITEST normally includes:
The tube containing the filter is directly screwed on the illumination housing. The standard green filter can be easily exchanged if necessary.
The Power Supply for standard illumination is an adjustable transformer which allow for adapting the light intensity to the specific application. The transformers include the power cable.
In some applications the light intensity of the standard illumination might not be sufficient. This is the case in procedures requiring auto-collimation with a small (uncoated) reflector or long distances between reflector and auto-collimator. 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 halogene lamps are recommended.
