GCC-5011 Protected-Gold 90° Off-Axis Parabolic Mirrors

Eight protected-gold 90° off-axis parabolic mirror options are distinguished by complete model, card diameter value, focal-length value and an explicit with-hole designation where present. The cards provide model-specific selection text but omit length units, focal-length references and hole geometry. These descriptions preserve the differences and the printed 101.2 without letting an engraving in the shared photograph override individual model data. Appearance is not treated as a mechanical drawing or evidence of pack quantity.

Models and card values

All eight options are designated protected-gold 90° off-axis parabolic mirrors. Card diameter-symbol and focal-length values are: φ50.8 and focal length 50.8 for 501111/501101; φ25.4 and 50.8 for 501105; φ50.8 and 101.2 for 501112; φ25.4 and 25.4 for 501104; φ25.4 and 101.2 for 501107; and φ50.8 and 152.4 for 501103/501113. No length unit is supplied, so mm is not added. The printed 101.2 is retained rather than corrected to 101.6.

Hole-designated options and interfaces

GCC-501111, 501112 and 501113 explicitly say with hole. The other five cards omit that wording, which does not guarantee the absence of every hole. Hole position, direction, diameter, through-hole status and purpose are unspecified. Shared photographs do not establish individual hole geometry. Obtain mechanical drawings for clear aperture, thickness, clamping, rear interface, tolerances and holder compatibility.

Coating, angle and focal-length definition

Protected gold 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 gold-colored 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.
