P12607 Hybrid delivers Notch centre 549.7 nm, Notch width (FWHM) 185.4 nm, and Notch depth OD ≥ 2.8 (T < 0.15%).
The hard-oxide coating is built for repeated handling, heat, and cleaning.
Best suited for:
Fluorescence imaging systems, laser safety filters, environmental monitoring instruments, and optical systems with broad spectral isolation needs.
Description
The P12607 provides extended wavelength coverage with a 185 nm notch spanning 471-615 nm and exceptional 95.6 % peak transmission. Operating at 0.15 % depth at 527 nm, this filter transmits 91.2 % in the blue region and 93.3 % in the red-NIR band. Its broad notch width makes it particularly suitable for applications requiring suppression of extended green-yellow wavelengths in dual-channel detection systems.
Key Advantages
- Extended Notch Bandwidth - 185 nm blocking range suppresses green, yellow, and orange wavelengths simultaneously for complete mid-visible rejection
- Ultra-Low Notch Depth - 0.15 % transmission at 527 nm provides excellent attenuation of environmental green light and laser scatter
- Hard-Oxide Multilayer Construction - Ion-assisted deposition ensures long operational life under thermal cycling and high-power illumination
- Versatile Format Availability - Round, square, and custom free-form geometries on standard substrates ranging 5-450 mm with 0.21-3.8 mm thickness
- High Red-NIR Transmission - 93.3 % across 652-780 nm maximizes signal collection in far-red and NIR imaging
Typical Applications
- Biomedical Fluorescence - Separates blue-excited cyan fluorescence from red and far-red indicators in multicolor assays
- Raman Spectroscopy - Blocks 532 nm excitation laser while transmitting Raman signals across separated violet and NIR regions
- Multispectral Remote Sensing - Enables blue and red channel discrimination in agricultural and environmental monitoring
- Laser-Induced Breakdown Spectroscopy - Isolates blue continuum emissions from red atomic lines in LIBS instrumentation
- Stage Lighting and Display - Creates vibrant magenta color spaces in theatrical, broadcast, and AR/VR applications
Prototyping completed within 2-3 weeks; full production runs support rapid product development and manufacturing scale-up.
