Lockwood Custom Optics, Inc. - Information

Me and a mirror Welcome to the Lockwood Custom Optics web site.  My name is Michael Lockwood, and I started LCO in 2006 to supply quality optics to amateur and professional astronomers, telescope builders, scientists, researchers, and industry.

I specialize in high quality optics and give each optic individual attention in figuring and testing to make it the best it can possibly be, no matter if it is one of many or a single custom piece.  I also understand that quality custom optics are not easy to find, and I want to be a dependable source.

I am a source for high-quality optics and services such as:

As for customer service, I specialize in: For astronomical use, products from Lockwood Custom Optics produces high-accuracy optics that produce high-contrast, high resolution images that will allow your instrument to excel in its application.  For scientific and other uses, LCO represents one of the best values in LIDAR and other types of optics.

Other important notes

Before placing an order, please read my FAQ.  It contains answers to lots of questions, and also discloses some terms and conditions of sale.

Large mirrors - I can currently provide mirrors up to ~32" in diameter from high-quality, precision annealed, monolithic borosilicate glass up to 2.1" in thickness.   This is very good glass, and it is usually available 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.

PLEASE NOTE - EMAIL (in general) DOES NOT ALWAYS WORK!  Technology has made communication easier, but certain email addresses are blocked by certain filters, messages sometimes simply disappear, and that is not your or my fault.  So, If you've tried to contact me and haven't heard back, there is a significant chance that the email got eaten by the internet or a spam filter.
