Elliptical/Flat Optics

All current production is with Fused Quartz. Most ellipticals diagonal mirrors are in stock!.

We are having a really good production run of Ellipticals 4.5" and larger. If you will be needing one soon, or even within the next year, let me know so I can get enough of them processed to cover everyone.

ELLIPTICAL and ROUND FLATS

We manufacture optical flats in just about any size, shape and material, including your material. If you need something other than listed below, send us a detailed message of what you need and we will provide you with a quotation.

Testing throughout is done by non-contacting interferometry whenever possible and are tested at full aperture whenever possible. All of our elliptical/flat optics are precision pitch polished and have excellent surface quality, thoroughly inspected at every stage of manufacture. Our enhanced aluminum coatings are applied for 45-degree angle of incidence.

We purchased a large batch of Quartz diagonal blanks from ProtoStar. We are processing them and we will add them to this site as they become available. A majority of them are for upgrades for import telescopes. Our first available size is 70mm (2.75") minor and they are ready to ship. Call Frances for current pricing, Thanks!

Large elliptical Diagonal Flat Mirrors

We are using fused quartz for our substrates. Our blanks are diamond machined on all sides. A safety bevel is provided, front and back, for safe handling. Precision polished until 1/10 wave or better, P-V is usually much better. I can "hand-select" one for you! Test data with serial number provided. Includes our enhanced aluminum coatings.

We try to have most sizes in stock!

Call, text or e-mail for pricing. We will continue

to manufacture elliptical diagonals for the

Astronomical community for the foreseeable

future.

All sizes 5.00" and larger are 1.0” thick.

Enhanced aluminum coatings at 45 degree angle of incidence optimization.
