This page gathers the infrared programme that the rest of the site divides by component. The material set is documented in the window listings: ZnSe window plates, ZnS and calcium fluoride window plates in a combined CO2 laser line, and a multi-material assortment naming infrared silicon among its window materials. Infrared optics is also one of the twelve product categories under which the manufacturer is registered in the RP Photonics buyer's guide, alongside lenses, mirrors, prisms, filters and waveplates — an independent directory registration that matches the storefront catalogue.
ZnSe Windows
AR coated, 10-piece documented minimum.
Germanium Windows
Category enquiry notes. No germanium listing is recorded in the source catalogue; availability is confirmed by enquiry.
CO2 Laser Lenses
ZnSe focus lenses, 20 mm diameter, 50.8 mm focal length.
Laser Mirrors
Silicon gold-coated CO2 reflectors and galvo mirrors.
Infrared Filters
Infrared transmitting and narrowband filters for IR instruments and sensors.
How the Infrared Programme Divides
By band and by job. Germanium is a general material candidate for the long-wave band, but it is not a documented listing here. CO2 laser delivery and focusing work through ZnSe lenses and windows and gold-coated silicon mirrors. Sensing and detection work through infrared filters — the documented infrared transmitting filter for sensors and the 850/940 nm narrowband lines — which select the band the detector sees. A buyer specifying an infrared instrument can name two or three of these in one enquiry against one band plan; any combination is confirmed item by item in the quotation.
For a germanium requirement, first confirm availability: no germanium size, coating, stock range or minimum quantity is published on this site because no germanium listing is recorded in the source catalogue. Send the band, the component list and the environment; the documented part of the quotation will work in the recorded materials, and any germanium item must be confirmed separately in writing.
Frequently Asked Questions
Which infrared materials are documented?
ZnSe, ZnS and calcium fluoride in the window plate listings, and infrared silicon in the multi-material window assortment. Germanium is not recorded as a documented listing and requires a separate availability confirmation.
Is infrared optics a registered category for this manufacturer?
Yes — infrared optics is one of the twelve categories in the manufacturer's RP Photonics buyer's guide registration.
Can I quote an infrared set as one order?
Documented windows, filters, mirrors and focus lenses can be discussed against one band plan. A germanium item must first be confirmed as available; it is not part of the documented set.
Specifying an Infrared Set: The Band Plan Habit
Infrared systems fail at interfaces between components, because each part was specified against a slightly different idea of the band. The working habit against it is the band plan: one line in the enquiry stating the instrument's working band, its source or scene, and its detector, followed by the component list that must serve that band. Against a band plan, each window's material, each coating and each filter edge is confirmed against the one band stated in the enquiry, rather than each against its own assumption. The documented programme on this page lists ZnSe, ZnS and CaF2 window plates, infrared silicon windows, infrared filters and the CO2 laser set; each item in a mixed infrared order is confirmed item by item in the quotation, against the one band plan in the enquiry. Germanium is not part of that documented set, so a germanium item must be confirmed separately before it joins a mixed order.
