Lockwood Custom Optics

Custom telescope mirrors, 16"- 52" in aperture, F/2 and up
Newtonian, classical Cassegrain, and Ritchey-Chretién systems
Refiguring for systems 6"- 52" in aperture
Custom flat mirrors - elliptical or round, and flat testing

Welcome to the Lockwood Custom Optics web site. My name is Michael Lockwood, and I make optics for amateur and professional astronomers and telescope builders.

I specialize in high quality custom optics (rather than doing large production runs of one type of mirror) because I believe in giving each optic individual attention in figuring and testing to make it the best it can possibly be. If I can measure significant error in a mirror, it is simply not good enough, and must be worked further.

I am a source for difficult to find, high-quality optics and services such as:

Large Newtonian primary mirrors (focal ratios of F/2 and up)

Custom-made Cassegrain optical systems

Large elliptical diagonal mirrors

Closely matched optics for binocular reflecting telescopes

Custom-made Cassegrain secondaries, and

Testing and refiguring of assembled Cassegrain systems/telescopes

As for customer service, I specialize in:

Communicating with my clients, whether problems arise or not

Keeping clients updated on project progress

Delivering products in a timely manner, and

Flexibility in scheduling and custom services.
Providing clients with information on how to best use my products

I can provide mirrors up to approximately 42" in diameter from monolithic borosilicate (Pyrex or Pyrex-equivalent) glass from 2" to 3" in thickness. This glass is available to me now, with little delay. I specialize in high-quality, fast, large and thin optics, and I will help to make your large-aperture telescope a reality and success.

If you're looking for the lowest price on a telescope mirror, or for a standard Newtonian primary mirror under 12" in aperture, please look elsewhere. For smaller quality custom optics and Schiefspiegler systems, I recommend that you email Dick Wessling at The Pines Optical Shop - PinesOP(at)aol(dot)com.

I make custom optics, so I generally don't have finished mirrors in stock, and my prices are generally (but not always) higher than those that do. However, I usually have some generated mirror blanks that are ready for work. For a list of any items I may have in stock, please click here.

The bulk of my work is for the clients listed in the table on the first web 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. (Please note that 14.5" F/4, 16.5", 18", 20", 24", and 28" F/3.7, and 22", 28", and 30" F/3.3 mirrors are exclusive to Starmaster, and are not available for private sale at this time.) While these valued clients keep me fairly busy, I have some time available for projects that require quality optics. If you have such a project, please email me at:
