From the word, ‘uni,’ Uniray is a single-beam index system that provides a direct signal which tends to be independent of picture modulation. It does not involve the tracking of beam light and does not need extreme sweep linearity. In comparison to the aperture-grill system or shadow mask, Uniray optics which focuses on independent visualization also contains performance benefits. Such include increased efficiency, sharper images throughout the life-span of the equipment, and the allowance of exceptional brightness for every high voltage supply. Some of the available Uniray Optics wear the frontal, MAXX 30, the sporty and the fit over glasses.
Enhanced Value for Uniray Optics
Uniray Optics requires well-designed electron optics. It also needs additions of small, low-level circuits which are inexpensive and are readily available in integrated forms. These additions bring in the unique cost-effectiveness of the Uniray optics. With this, there is the elimination of several costly and bulky parts applied in the shadow-mask system types.
Major Feature Considerations
Some of the main characteristics associated with the Uniray Optics are the source of significant considerations by many. They include:
1) Light Source
Lenses and Mirrors-They help to decrease the distance of exit light. They also make straight the optical path.
2) Uniform Distribution
Reflects on the appropriate number of internal reflections
Lowering the cross-sectional area will create difficulty in aligning the optical system. There will be a need for added focus lenses
Raising the number of internal reflections increases uniformity. However, the size of the system remains enlarged.
Fly Eye Lens
Consider the appropriate number of cell lens
Raising the number of cell lens increases uniformity but lowers the level of brightness.
For micro mirror-glass array, the stray of light should not be incidental to the projection lens system. Such an alignment may produce image flaring.
In the case of using a simple mirror-glass, there is a need for careful alignment of the optical axis.
Whenever there is a rise of incidental angle, there should be a lowering of the f-number of the projection lens.
F-number is the focal length ratio of the system, to the diameter of the entrance pupil.
4) Projection Lens
For LED system- Should contain an f-number of 1.8-2.4
For Laser system- Should contain an f-number of 3.2 or greater
Various Uniray ranges of the eye-wear offer comfortable light frames with increased absorption of scattered radiation. They contain high resolution, a change of reflection angle, and with low polarization loss – read article on matte black glasses mens.
