An optical mirror is a flat or curved substrate plus a coating, and the coating on a given listing is one of the fields the enquiry confirms for that listing. The manufacturer's recorded mirror group lists four coating families by name: aluminized mirrors, gold-plated mirrors, silver-plated mirrors and dielectric film mirrors. Documented listings include big first-surface mirrors offered with silver, gold or dielectric coatings — first-surface listings, coated on the front face. The mirror group is also one of the manufacturer's headline product categories, listed in its main product range alongside lenses, windows, prisms and filters.
Curved forms sit in the same range: a customised 300 mm K9 glass concave reflecting mirror is a documented listing. Two more documented listings are OEM optical glass silver coated reflective mirrors for laser processing, and factory custom flat glass aluminium coated reflector mirrors. The catalogue's reflector mirror group also names aluminised, gold-plated, silver-plated and dielectric film mirrors.
Documented Mirror Families
| Family (storefront group) | Documented listing (storefront name) |
|---|---|
| Aluminized mirror | UV-enhanced aluminium coated reflector mirror |
| Gold-plated mirror | CO2 laser optical mirror, silicon gold coating |
| Silver-plated mirror | OEM silver coated reflective mirror (laser processing) |
| Dielectric film mirror | Round or square plano dielectric coating high reflectivity mirror |
For laser-dedicated mirrors — silicon gold-coated CO2 reflectors, galvo scanning mirrors and high-reflectivity dielectric parts — the laser mirrors page goes deep. For the coating technology itself across all component types, see optical coating. Documented mirror listings carry 10-piece minimums; pricing follows substrate, coating and quantity and is confirmed in the written quotation. An enquiry for a specific family should name the coating family and the band the mirror must serve.
Frequently Asked Questions
First surface or second surface — which do you supply?
Optical service means first surface: the documented big first-surface mirror listing is coated on its front face, and that coated face is the reflecting surface.
Which coating for the infrared?
A gold-coated silicon CO2 laser mirror is a documented listing; the coating for a given infrared band is confirmed per listing in the enquiry.
What is the minimum order?
10 pieces on the documented mirror listings.
Flatness, Substrates and the One-Inch Habit
Mirror specifications beyond the coating repay a short checklist. Flatness is where a mirror specification starts — a steering mirror in a delivery path can be modest, while a mirror inside an interferometer or a laser cavity is part of the optical design and its flatness belongs in the first line of the enquiry. Some documented listings state their substrate — glass on the documented JGS1, K9, OEM optical glass and flat glass reflector listings, and silicon in the documented gold-coated silicon reflector line — and where a listing does not state one, the substrate belongs in the enquiry. Size follows the beam with margin — the working rule is a clear aperture comfortably larger than the beam footprint at the mirror's working angle, remembering that a round beam at 45 degrees paints an ellipse. And format follows the installed base of mounts: the documented 25.4 × 3 mm dielectric reflector is the one-inch format, so the mount you already own belongs in the enquiry alongside the mirror's size.
