GCL-0604 Optically Contacted Quartz Zero-Order Wave Plates

The GCL-0604 optically contacted quartz zero-order waveplate family contains 11 online SKUs. Inspected images establish half-wave retardance and corresponding nominal wavelengths for nine models. Two models lack dedicated images and retain their category and code while awaiting individual specification data. The GCL-060417 image prints 7800 nm, an unresolved value preserved for confirmation rather than silently corrected. GCL-060412 likewise retains its source value of 633 nm. The φ25.4 notation has no dimension unit or diameter definition. These descriptions distinguish confirmed information from gaps for each model. Optically contacted preserves the source construction category without describing adhesive glue. English artwork is a circular-optic appearance reference, not an internal construction or calibrated engineering diagram.

Model-specific data and missing images

Nine models have inspected image evidence for half-wave retardance, their corresponding wavelengths and φ25.4. GCL-060418 is documented in main003. GCL-060434 and GCL-060431 have no dedicated images or individual parameters; only the model and family category are retained. Their suffixes do not establish half-wave retardance, wavelength or dimensions.

Source anomalies and literal values

The GCL-060417 image literally states 7800 nm. That unresolved value is retained for supplier confirmation rather than silently changed to 780 nm. GCL-060412 states 633 nm, which is not replaced by another family’s 632.8 nm. Nominal wavelengths are not combined into a continuous operating range. φ25.4 lacks a dimension unit and diameter definition.

Optically contacted quartz zero-order configuration

The source category is translated as optically contacted quartz zero-order waveplate. Optical contacting is not described as adhesive cementing, and the family is not reclassified as air-spaced, multi-order or polymer. Internal plate count, contact surfaces, retardance accuracy, crystal axes, thickness and temperature response are unspecified.

Appearance, selection and supply

Shared photography shows one blue circular optic with a pink edge. Color does not establish coating or wavelength. Confirm actual wavelength, retardance, accuracy, clear aperture, clamping, alignment, damage conditions and inspection records. The source offers custom sizes and lists 2–7 days for dispatch; confirm accessories, quantity, stock and actual delivery.
