G73814 passes a vivid, highly saturated band of mid-green while
tamping stray photons down to the noise floor. Transmission breaks 90 % near
526 nm, stays above that level to ~570 nm, and plunges below one percent by ~600 nm.
UV/blue energy is suppressed to near zero (aside from an < 8 % ripple around
390 nm that KUPO can flatten on request), and yellow-to-near-IR light remains
suppressed right out to ~760 nm—where only a gentle tail rises to under 6 %.
KUPO coats Borofloat®, soda-lime, Schott D263 T, or Corning Eagle XG substrates cut
to any outline—from 5 mm chips to 450 mm plates—with thicknesses of
0.21 – 3.8 mm, and can ship prototypes in about two weeks.
Typical uses: FITC-style fluorescence excitation, green-LED machine vision,
RGB laser/LED projection, discrete green channels in multispectral cameras, saturated
stage lighting, and AR waveguides needing bright green injection free of UV/IR heat.
Description
The G73814 delivers an exceptionally broad 63 nm passband centered at 553 nm with 94.4 % peak transmission. This wide-aperture filter balances substantial spectral breadth with outstanding blocking characteristics, making it ideal for applications requiring maximum green-to-yellow collection without spectral compromise.
Key Advantages
- Maximum Spectral Breadth – 63 nm passband spans 523-575 nm with > 92 % average transmission for maximum photon collection
- Ultra-Clean Out-of-Band Rejection – Blocks 98.97 % of UV light and 99.23 % of red/NIR light, achieving exceptional two-sided extinction
- Hard-Oxide Ion-Assisted Durability – Superior coating resists mechanical wear, chemical exposure, and environmental contamination across extended deployment
- Peak Transmission Excellence – 94.4 % at 553 nm ensures maximum detection sensitivity even in low-light applications
- Complete Customization Range – Order as round, square, or free-form optical blanks (5-450 mm) on Borofloat, soda-lime, Schott D263 T, or Corning Eagle XG at your chosen thickness (0.21-3.8 mm)
Typical Applications
- Wide-Field Fluorescence Microscopy – Illuminate large samples uniformly with broad spectral acceptance while collecting from multiple green-yellow fluorophores
- Stage Lighting and Gels – Create vivid yellow-green theatrical colors by filtering tungsten lamps with efficient broad-spectrum acceptance
- Airborne Remote Sensing – Monitor vegetation health using broad green reflection signature from aircraft and satellite platforms
- Holographic Reconstruction – Reconstruct wide-bandwidth holograms recorded at yellow-green wavelengths for high-brightness display applications
- Multi-Stain Microscopy – Simultaneously detect multiple green-shifted fluorophores (FITC, Alexa 488, mCherry fusion variants) in single-filter systems
Integrate G73814 for broad-spectrum green-yellow detection; rapid prototyping and full production volume capability assured.
