K9 High-Precision Flat Metal Mirrors — GMH12 Series
From $19 USD
Request a quoteProduct description
GMH12 high-precision flat mirrors use fine-annealed H-K9L optical glass and a plane reflecting surface for beam steering, interferometry and imaging assemblies. General source specifications include λ/10 surface figure at 633 nm and 10-5 reflective surface quality.
The 70 source models include circular and rectangular sizes and five coating choices: uncoated, protected aluminum, protected UV-reflective aluminum, protected silver and protected gold. Individual model dimensions and coatings take precedence.
The source general description and gallery refer to enhanced aluminum, while the individual aluminum model rows say ordinary aluminum with protection. This distinction is retained in the model specifications and reference curves.
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 and avoid touching or wiping metallic reflecting surfaces. For model-specific drawings or CAD files, include the model number in your inquiry.

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.
