With antireflection coatings, there are far less opportunities to lose necessary light while maintaining an acceptable level of contrast. These coatings are also beneficial for eliminating light reflection, which can interfere with the accuracy of telpes, imaging equipment, and other optical devices used in the astronomical industry.
A telpe mirror is designed to form a diffraction limited image of a point source. Ideally, a certain percentage of the light in the image will fall within the diffraction disk diameter. The Strehl ratio compares the mirror''s actual performance in terms of its ability to .

If you make the centre deep, you will end up with a fast telpe ( F/D = 4) well suited for deep sky observations. On the opposite, a shallow mirror ( F/D = 8) will be performing very well on planets and the moon.
