GCL-1201 Sapphire Optical Windows

The source lists GCL-120101 and GCL-120102 sapphire windows in the GCL-1201 series. Their individual cards stateφ12.7,d1.0 andφ25.4,d1.0 respectively. Diameter markings are retained,but units and the meaning of the d field are not supplied. Verified millimeter thickness and clear aperture are therefore not added. English artwork follows the blue circular-window appearance in the original photography; color does not establish coating or transmission spectra. These descriptions distinguish the explicit sapphire category and original card markings from open performance questions. Material grade,crystal orientation,operating band and mechanical fit require documentation for the selected model. Confirm mounting and sealing requirements alongside the optical specification before assessing suitability.

Models and card markings

The GCL-120101 card statesφ12.7,d1.0; GCL-120102 statesφ25.4,d1.0. The diameter symbol is explicit,but no unit or clear-aperture definition is given. The d1.0 marking has neither a field explanation nor a unit and is not converted into a verified1.0 mm thickness. Complete identities follow individual cards without decoding model digits.

Sapphire category and optical data

The source explicitly identifies sapphire windows. Crystal orientation,material grade,coating status,operating band,transmission,reflectance and damage threshold are unspecified. The name does not establish numerical infrared-transmission,temperature or pressure guarantees. Photographic blue color is not evidence of an antireflection coating or spectral performance; obtain model-specific test data.

Appearance and mechanical use

Both options reuse photography showing two blue circular plates with pink-purple edges. Appearance supports family identification rather than a two-piece pack,actual model proportions or individual geometry. Thickness,diameter tolerances,surface figure,parallelism,wedge,chamfers and clamping interfaces are unconfirmed. Focal length and focusing functions are not added to a window description. Check mounting and sealing requirements against engineering drawings.

Selection,custom sizes and supply

The source custom-size offer does not establish additional stocked SKUs. Confirm units,the d-marking meaning,clear aperture,crystal orientation,coating and wavelength conditions before assessing mounting. Temperature,pressure,power,cleaning,accessories and pack quantity are unspecified. The source lists2–7 days for dispatch; check current stock,custom-size feasibility and actual delivery with the supplier.
