GCL-05 Polarizers

The current online GCL-05 family has two options: GCL-050003 and GCL-050004. Their source cards stateφ25.4 with500:1 andφ50.8 with100:1 respectively. The source does not supply a diameter unit or a field definition for either ratio. These descriptions retain those original values without converting them into verified millimeter diameters or guaranteed extinction ratios. A main image additionally names050005, which does not change the two-SKU online scope. The bilingual descriptions distinguish card facts from shared photography and open technical questions. English artwork shows the dark gray circular-disc family appearance, rather than establishing pack quantity, polarization type or exact engineering dimensions. Obtain model-specific optical and dimensional data before assessing suitability.

Two online model identities

The individual GCL-050003 card states polarizer,φ25.4 and500:1; GCL-050004 statesφ50.8 and100:1. Another main image names GCL-050005 withφ12.7 and500:1. That is retained as additional main-image information rather than added as an online SKU or assigned to another model. Complete identities follow the individual cards.

Diameter markings and ratio definitions

The diameter symbol is explicit, but no unit or outer-diameter/clear-aperture definition is provided. Millimeters are not assumed. The500:1 and100:1 figures have no field label; they are not converted into verified extinction ratios, minimum guarantees or performance at every wavelength. Confirm the ratio definition, measurement wavelength, angle, polarization and test conditions. The two model ratios are not interchangeable.

Category and appearance

The source calls these polarizers without specifying linear or circular polarization, absorptive or reflective operation, thin-film construction or crystal structure. GCL-0510 parameters are not transferred. Photography shows several dark gray circular discs with black edges; color, count and proportions do not establish substrate, pack quantity or exact dimensions. Axis markings, thickness, tolerances and mounting interfaces are unconfirmed.

Selection and supply

Operating band, transmission, damage threshold, power limits, temperature, cleaning method and accessories are unspecified. A custom-size offer does not establish additional stocked SKUs; confirm its scope. The source lists2–7 days for dispatch. Check complete model, dimensional definition, ratio, optical conditions, quantity, current stock and actual delivery when ordering.
