GCC-10220 Circular Protected Silver Mirrors

The source lists three protected silver round mirror options in the GCC-10220 series: GCC-102204, GCC-102206 and GCC-102201. Their individual cards carry diameter markings of φ40.0, φ12.7 and φ20.0 respectively. This description retains the source symbols and values without supplying a missing unit, clear aperture or thickness. All models share photography showing three circular optics, so the English artwork is a representative series image rather than proof of pack quantity, substrate or exact size. Selection requires model-specific spectral performance, mounting details and operating conditions. Current delivery, accessories and custom-size feasibility should be confirmed separately. Similar coating categories elsewhere in the catalog do not establish the complete technical specification for this family.

Models and diameter markings

The individual SKU cards identify GCC-102204 as φ40.0, GCC-102206 as φ12.7 and GCC-102201 as φ20.0. The diameter symbol is present, but no unit is given; neither millimeters nor clear aperture is assumed. The source heading uses GCC-10220 Series and mentions 102206. Complete identities follow each individual card, without decoding model digits into material or dimensions.

Protected silver coating and optical data

Protected silver is the coating category stated in the source, not evidence that the entire optic is made of silver. Protective-layer material, substrate, operating band, reflectance, incidence angle and polarization are unspecified. Parameters from rectangular protected silver mirrors or other silver-coated products are not transferred. A silver-gray appearance does not establish a spectral band, efficiency or damage guarantee; obtain model-specific test data.

Appearance and mounting details

All three models reuse photography of three round optics with silver-gray or dark reflective faces and substantial gray edges. Differences in brightness are photographic appearance, not verified model or performance distinctions. Three displayed pieces do not establish a three-piece kit. Individual engineering drawings are absent for thickness, surface figure, parallelism, dimensional tolerances, rear construction and clamping interfaces. Confirm included holders and quantity.

Selection, custom sizes and delivery

The source offers custom sizes without adding unlisted stocked SKUs or guaranteeing every requested size. Confirm the complete model, diameter unit, actual mounting dimensions and optical operating conditions before selection. The source lists 2–7 days for dispatch. Check current stock, quantity, accessories, custom-size feasibility, cleaning instructions and actual delivery with the supplier.
