K9 Standard-Precision Flat Metal Mirrors — GMH11 Series
From $13 USD
Request a quoteProduct description
GMH11 standard-precision flat mirrors use a plane reflecting surface for beam steering, interferometry and imaging-system optical assemblies. The source substrate is H-K9L optical glass, described as K9 in the series name.
The 94 source models include circular and rectangular sizes, with uncoated, protected aluminum, protected UV-reflective aluminum, protected silver and protected gold options. Select the actual model coating and dimensions in the specification table.
The source general description and gallery refer to enhanced aluminum, while individual aluminum model rows say ordinary aluminum with protection. This distinction is retained: source reference images do not redefine a model coating.
Flat mirror reflection schematic
Angles are measured from the surface normal; this illustration does not specify model dimensions.
Drawings are reference illustrations and may differ from an actual part. Handle mirrors at non-optical edges with gloves; avoid touching or wiping metallic reflecting surfaces. Use an air blower for loose surface contamination. Source model attachment paths are retained in the catalog evidence; unverified files are not advertised as confirmed downloads.

Technical notes
For a plane mirror, the reflected angle equals the incident angle, measured from the surface normal. The diagram illustrates 45°, normal and arbitrary incidence.
Review the material, dimensions and other specifications listed for the individual model. Check any available curves against the model's stated operating range.
Illustrations and printable specification summaries are reference information, not manufacturing drawings. Confirm technical suitability and final requirements with your quotation.
