Red-NIR Transition Bandpass Filter

The BP780-60 Bandpass Filter is precision-engineered for applications requiring spectral coverage at the critical transition between visible red and near-infrared wavelengths. With its 780nm center wavelength and balanced 60nm FWHM, this filter delivers excellent performance for biomedical imaging, fluorescence applications, and spectroscopic analysis in this unique spectral region.

Key Features:

  • Red-NIR Optimized: 780nm center wavelength at the visible-NIR boundary
  • Balanced Bandwidth: 60nm FWHM for optimal spectral performance
  • High Transmission: >88% peak transmission in passband
  • Superior Blocking: Excellent rejection of shorter visible and longer IR wavelengths
  • Professional Grade: Hard-coated surfaces for demanding applications
  • Temperature Stable: Minimal wavelength shift across operating range

Specialized Applications:

  • Fluorescence microscopy and cell imaging
  • Biomedical imaging and diagnostics
  • Agricultural and vegetation monitoring
  • Industrial quality control and inspection
  • Laser diode characterization
  • Spectroscopic analysis and research

Technical Specifications:

  • Center Wavelength (CWL): 780nm
  • Full Width Half Maximum (FWHM): 60nm
  • Passband Range: ~750nm to 810nm
  • Substrate: High-quality optical glass
  • Coating: Multi-layer transition coating
  • Surface Quality: 40-20 scratch-dig
  • Parallelism: <30 arcseconds
  • Clear Aperture: >90% of diameter

Transition Region Advantages:

The 780nm wavelength offers unique benefits:

  • Bridges visible red and near-infrared spectral regions
  • Excellent for fluorescence applications with red-shifted fluorophores
  • Optimal for vegetation analysis and chlorophyll studies
  • Compatible with both silicon and InGaAs detectors
  • Reduced scattering compared to shorter visible wavelengths

This spectral region (750-810nm) is particularly valuable for applications requiring the transition from visible to NIR, making it ideal for fluorescence imaging with far-red fluorophores and vegetation analysis where chlorophyll absorption characteristics change dramatically.

Perfect for researchers and engineers working with fluorescence imaging, biomedical applications, and agricultural monitoring where the unique properties of the red-NIR transition provide enhanced analytical capabilities. Each filter undergoes comprehensive testing to ensure consistent performance across this critical spectral region.

Optical dicing refers to precision cutting processes used to segment optical materials, particularly those with specialized coatings, into smaller functional components while maintaining their structural and optical integrity. In the context of optical coating flats (flat substrates like glass, fused silica, or semiconductors coated with anti-reflective, dielectric, or other optical layers), dicing ensures these coated substrates meet exact dimensional requirements for applications in photonics, lasers, sensors, and semiconductor devices.

Methods

  • Saw Dicing: Diamond-coated blades for clean cuts with minimal chipping.
  • Laser Dicing: Non-contact ablation for delicate or brittle materials, reducing mechanical stress.
  • Plasma Dicing: Dry etching for ultra-fine features, ideal for advanced semiconductor wafers.

Price

Dicing Service will generally cost from $50 to $125 per piece. Depending on the accuracy and size you are requesting.

Fequently Asked Questions

What are the Thickness of the Optical Filters?

For Mounted Optics:

  • 6mm (by Default)
  • 3.5mm (Specified in Order Note)

For Unmounted Optics:

  • 0.5mm
  • 1.1mm
  • 2mm

(most of the unmounted optics are having thickness of 1.1mm ~ 2mm)

What is the difference between mountings?

Unmounted:

  • a bare glass optical filter

Mounted:

  • Smooth Mount for protection of the optics. No thread is there on the mount.

Metric Mount:

  • Start with M as prefix, usually seens as M25.5x0.5mm. Mostly used as camera filters

Imperial Mount (Usually Thorlabs):

  • Start with SM as prefix, usually seen SM1, SM05 etc... Mostly used in Optical system. (You will have a SM external thread to connecting to other objects)

C-Mount:

  • Very frequently used mounting. C-Mount is 1‘’-32TPI. And it is not the same thing as SM1, or M25.5x0.5mm.
