can currently provide
mirrors up to ~32" in diameter from high-quality, precision
monolithic borosilicate glass up to 2.1"
in thickness. This is very good glass, and it is usually
with little wait. I will help to make your large-aperture
telescope a reality and
success, not only by making high-quality optics, but also with mirror
cell advice. For larger sizes, I can often find substrates in
quartz or other materials.
Small mirrors - I prefer to make new monolithic mirrors that are 14.5" or larger. For 8" - 14" optics, I highly recommend Carl Zambuto. I refigure mirrors as small as 10". I work quality cast or machined cellular blanks and flats. I do not make small flats, and I prefer to refigure flats only when I am working on or testing a primary that goes with it. I am now only supplying flats for clients who are buying a primary or are having one refigured by me.Mirror cell testing- I have extensive experience with mirror cells for alt-azimuth Newtonian telescopes, and I can provide some testing and validation results for the edge support of a mirror cell. This is a useful and often vital testing step that many telescope builders have never even considered, and which is very important for large, thin mirrors.
Experience and typical work: I have considerable experience in working thin mirrors, cast cellular mirrors, and sub-F/4 optics, and combinations thereof. I make custom focal ratios and can supply a specific focal length to close tolerance if required.I generally don't have finished mirrors in stock, though I hope to change that in the future. However, I usually have some generated mirror blanks that are ready for work. For a list of any items that I may have in stock, please click here, and see if that gives you some project ideas.
Much of my work is for the clients listed on my Clients page, and I thank them for choosing to work with me based on the quality of my work, adaptability to meet their needs, timely delivery, and dependability. My Projects Page lists many, but not all, of the other projects that I have been involved with.
