GCC-5013 90° Silver-Coated Off-Axis Parabolic Mirrors

Five protected-silver 90° off-axis parabolic mirrors are distinguished by complete model, φ value and focal-length value. Cards supply model-specific selection text without length units or a focal-length reference. These descriptions retain the printed 101.2 and individual differences rather than letting the shared F=152.4 engraving override card data. Hole-designated configurations, materials and performance from the protected-gold family are not transferred. Series artwork supports appearance only, not exact engineering curvature or pack quantity.

Models and card values

GCC-501305 lists φ25.4 and focal length50.8; 501304 lists φ25.4 and25.4; 501306 lists φ25.4 and76.2; 501307 lists φ25.4 and101.2; 501302 lists φ50.8 and101.2. All cards specify protected silver and90°. Length units are absent, so mm is not added. Printed101.2 is not corrected to101.6, and model digits are not decoded.

Mechanical interfaces and construction

None of the five cards carries a with-hole designation. This does not guarantee the absence of every hole, and hole configurations from protected-gold models are not assigned. Holes, rear interfaces, clear aperture, body height, clamping areas and tolerances are unspecified. Reused photographs are not individual mechanical drawings. Obtain the selected complete model drawing before confirming holder compatibility.

Coating, angle and focal-length definition

Protected silver is an explicit source designation, not an inference from photographic color. Protective-layer composition, substrate, reflectance spectrum, operating band, surface figure, surface quality and damage threshold are absent. The 90° series label is not automatically converted to a 45° incidence-angle specification or a ray diagram. Focal length is not defined as parent, effective or reflected focal length, nor is its measurement reference specified.

Photographs and supply

Cards reuse three views, including a body engraving of F=152.4. That engraving does not override other models’ card values. Dark cylindrical bodies and sloped silver-gray faces establish appearance only, not a three-piece pack, included holder or each model’s scale. Custom sizes are offered without a separate custom SKU. The source lists 2–7 days for dispatch; confirm current delivery, quantity, accessories and cleaning conditions.
