GCC-2111 Dielectric-Coated Longpass Filters

Twelve dielectric long-pass filter options are identified by complete model. Every SKU card reuses the same three-filter series photograph without model-specific wavelength, dimensions or spectral data. These descriptions preserve each option’s identity and visible construction while identifying missing information. The shared 400, 450 and 550 nm engravings are not assigned as confirmed specifications to any individual option.

Models and wavelength information

The source lists GCC-211101, 102, 103, 104, 105, 106, 107, 109, 110, 111, 113 and 117: twelve options. Each card gives its model but reuses a photograph engraved L400nm, L450nm and L550nm. No table maps these labels to individual models. Wavelengths are not assigned by model-number order, and missing model numbers are not added.

Dielectric long-pass designation and spectra

The source explicitly identifies dielectric long-pass filters without an edge definition, transmission, blocking range, optical density, edge steepness or spectral curves. Model-specific wavelengths, tolerances, incidence angles and polarization data are absent. Reflected color and photographic arrows do not substitute for a spectrum or installation-direction instructions. Obtain a data sheet for the complete model before ordering.

Appearance and mounting dimensions

Reused photographs show circular optical surfaces in black rims. A three-item display and its reflections do not establish a three-piece pack. Diameter, cell height, clear aperture, substrate, frame material, threads, tolerances and clamping requirements are unspecified. Φ25.4 or Φ12.7 dimensions and holder compatibility from other GCC series are not assigned to this family.

Operating conditions and supply

Custom sizes are promoted without a separate custom SKU; agree wavelength, spectral requirements, dimensions and delivery separately. Temperature limits, laser damage threshold, permitted power, cleaning requirements and quantity are absent. The dielectric-coating designation does not establish a particular layer stack, glass type or high-power capability.
