Coating is a specification field in its own right on this catalogue's listings. The catalogue's right-angle prism listings include a light splitter prism with a dielectric coating — the record holds the listing's name and its coating, and does not state which face carries the coating. This page collects the coating evidence across the catalogue so a buyer can see the film options as one capability rather than as scattered listing details.
Documented Coating Evidence

| Aluminium coating | Aluminized mirror family; UV-enhanced aluminium reflector for UV service |
| Gold coating | Gold-plated mirror family; silicon CO2 laser beam reflectors |
| Silver coating | Silver-plated mirror family; OEM laser processing reflectors |
| Narrowband coating | Customised narrowband coating green bandpass filter (fluorescent) — a documented listing |
Specifying a Coating Job
A coating enquiry needs the substrate and its dimensions, the wavelength band, the function (anti-reflection, high reflection, partial reflection, band selection) and the angle of incidence. Those five items are the fields the film design is quoted against. Coating is normally quoted as part of the finished component — the window, mirror or filter it belongs to — so specify the component with its coating requirement in one enquiry rather than separating substrate and film into two conversations.
Workshop imagery of coating and production processes appears in the manufacturer's storefront gallery and is shown on the about page with its gallery attribution stated as published; no coating performance figure is published on this page that the underlying listings do not document.
Frequently Asked Questions
Can you AR-coat a window for a specific wavelength?
AR coating on ZnSe windows is a documented listing; state the wavelength the coating must serve, and ask in the enquiry for the design centre to be confirmed for that wavelength.
Do you coat components separately from supplying them?
Coating is quoted as part of the finished component in this programme — specify substrate and coating together in one enquiry.
Which coating for a CO2 laser mirror?
Gold on silicon is the documented CO2 construction; dielectric high-reflective coatings serve specified bands — see the laser mirrors page.
How to Read a Coating Quotation
Coating quotations reward the same discipline as coating specifications: compare like with like. Two quotations for 'AR coating' can describe films centred at different wavelengths, designed for different incidence angles, with different durability — all honestly labelled. The comparison fields are the band, the angle, the substrate the film is designed on, and the environmental duty the film must survive, because a film's adhesion and hardness are part of its specification in production instruments even when they are invisible in the optics. Buyers should also note the sequencing fact that coating usually follows substrate finishing, so coated components carry the lead time of both operations; ordering the component and its coating as one specification, as this programme does, keeps that arithmetic honest. The short version: state band, angle, substrate and duty once, in the first message.
