GCCH-102 Metal-Coated Mirrors

Eight metal-film mirror options are identified by complete model. Every card reuses a photograph of three gold-colored circular mirrors in different sizes, without individual dimensions, coating composition or numerical precision data. These descriptions retain each model’s identity, the source metal-film designation and visible circular construction while flagging missing material, optical and mounting data. Photographic color is not used to invent a gold-coating specification.

Models and configuration differences

The eight options are GCCH-102203, 102303, 102205, 102305, 102125, 102105, 102103 and 102123. Cards identify the model without individual parameter tables. Digits are not decoded into diameter, thickness, material or coating grade. Obtain data for the complete selected model; unlisted models are not added.

Metal-film designation and precision

The source advertises high-precision metal-film mirrors but specifies no metal, protective layer, substrate, surface figure, roughness or scratch-dig grade. “High precision” is promotional wording and is not converted to λ/10, a flatness rating or certification. A gold-colored photograph does not establish gold coating or a copper substrate.

Appearance, dimensions and mounting

Photographs show three sizes of circular reflective faces with substantial dark edges; every card reuses this image. It provides neither scale nor individual dimensions and does not establish a three-piece pack, a combined configuration or an included holder. Diameter, thickness, clear aperture, tolerances, clamping position and rear construction are unknown. Dimensions and mounting compatibility from other families are not assigned.

Spectral and operating conditions

Operating band, reflectance curves, incidence angle, polarization, damage threshold, power, temperature and cleaning method are unspecified. Confirm coating and reflectance for the actual optical setup; the metal-film designation alone does not establish broadband coverage or high-power suitability. Custom-size promotion has no separate SKU. Confirm current delivery, quantity and accessories.
