GCC-2040/1 Notch Filters

Two notch filters are listed with wavelength labels of 1064 nm and 632.8 nm, source bandwidth values and OD6 rejection-depth labels. The source does not define the bandwidth measurement convention or supply complete spectra, mounting dimensions or test conditions. These descriptions retain each card’s values and their limitations; the two-filter photograph is an appearance reference only.

Models and wavelength labels

GCC-204004 is labeled 1064 nm; GCC-204001 is labeled 632.8 nm. The source identifies GCC-2040/1 notch filters without a center-wavelength definition, tolerance, operating incidence angle or polarization. Both options reuse the same blue/yellow-green two-filter photograph; surface color is not assigned as a verified appearance for either model.

Source bandwidth label and rejection depth

The 1064 nm option carries a 44 nm source bandwidth label; the 632.8 nm option carries 13 nm. The original term is “half-bandwidth.” Both state rejection depth OD6. The source defines neither the transmission threshold nor whether the width means FWHM or HWHM. OD6 has no stated test interval, conditions or certificate. Values are retained without recasting them as verified FWHM or band-wide rejection guarantees.

Appearance and mounting data

Photographs show circular reflective optical surfaces in shallow dark rims with two filters on display. Diameter, thickness, clear aperture, materials, threads, tolerances and orientation are absent. The two-item photograph does not establish a two-piece pack or a kit containing both wavelengths. Dimensions from other filter families are not assigned; obtain the selected model’s drawing and mounting requirements.

Operating conditions and supply

Passband range, passband transmission, secondary passbands, edge steepness, temperature limits and laser damage threshold are unspecified. OD6 does not establish permitted laser power. Custom-size promotion has no separate SKU. Confirm material, spectral requirements, dimensions, quantity, delivery and cleaning method separately.
