GCO-0501M Uncoated Collimation Test Optic

The source identifies GCO-0501M as an uncoated collimation tester. Its frame is marked60 × 67 × 25,and the product title describes an optic diameter of50 and thickness of20,without dimension units. These bilingual descriptions retain the complete model,configuration and stated meanings rather than supplying millimeters or clear aperture. Collimation tester describes the source use category while the actual test principle,interpretation method,accuracy and required supporting equipment remain open questions. English artwork follows the rectangular frame and circular optic appearance. The product is not presented as an electronic photodetector,power meter or complete system supplied with a light source and camera. Obtain model-specific technical and operating documentation before assessing suitability.

Model and original dimensions

GCO-0501M is the sole online model. The card states frame60 × 67 × 25 and an optic marking of50,D20; the product title explicitly describes optic diameter50 and thickness20. Those diameter and thickness meanings are retained from the title, but no units are provided. The three frame values have no axis definitions. Millimeters,clear aperture and tolerances are not added.

Collimation testing and uncoated configuration

The source identifies an uncoated collimation tester. Uncoated is an explicit configuration; antireflection or reflective coatings are not invented. Testing principle,fringe interpretation,measurement accuracy and sensitivity are unspecified. The product is not recast as an electronic photodetector,a power meter or a complete interferometric measurement system.

Optic and frame appearance

Photography shows a substantial black rectangular frame surrounding a circular optical element with a visible thick edge. Appearance does not establish substrate,surface flatness,parallelism,wedge angle or complete internal construction. Operating wavelength,usable beam diameter,incidence arrangement,clamping interfaces and mounting threads are absent. Optic diameter is not substituted for clear aperture.

Selection, custom sizes and supply

Confirm units,frame-axis definitions,optical clear aperture,test procedure,accuracy conditions and any required light source or viewing equipment before selection. The source custom-size offer does not establish additional stocked SKUs. Holders,light sources,cameras,accessories,pack quantity and cleaning method are unspecified. The source lists2–7 days for dispatch; check current stock,custom-size feasibility and actual delivery.
