Wide-Bandwidth Near-Infrared Bandpass Filter

The BP1080-140 Bandpass Filter is designed for near-infrared applications requiring extensive spectral coverage with excellent out-of-band rejection. With its 1080nm center wavelength and wide 140nm FWHM, this filter provides comprehensive NIR transmission ideal for broadband spectroscopy, multi-wavelength imaging, and applications requiring tolerance to wavelength variations.

Key Features:

  • NIR Optimized: 1080nm center wavelength for optimal NIR performance
  • Wide Bandwidth: 140nm FWHM for extensive spectral coverage
  • High Transmission: >80% average transmission across passband
  • Effective Blocking: Superior rejection of visible and far-IR radiation
  • Robust Construction: Hard-coated surfaces for industrial durability
  • Stable Performance: Minimal temperature-induced wavelength drift

Versatile Applications:

  • Broadband NIR spectroscopy and analysis
  • Multi-wavelength laser systems
  • Agricultural and food quality assessment
  • Biomedical imaging and diagnostics
  • Industrial process monitoring
  • Telecommunications and fiber optics

Technical Specifications:

  • Center Wavelength (CWL): 1080nm
  • Full Width Half Maximum (FWHM): 140nm
  • Passband Range: ~1010nm to 1150nm
  • Substrate: NIR-optimized optical glass
  • Coating: Multi-layer broadband coating
  • Surface Quality: 40-20 scratch-dig
  • Parallelism: <30 arcseconds
  • Clear Aperture: >90% of diameter

Wide Bandwidth Advantages:

The generous 140nm bandwidth makes this filter perfect for:

  • Applications with multiple NIR wavelengths or broadband sources
  • Systems requiring tolerance to laser wavelength drift
  • Temperature-sensitive applications with varying operating conditions
  • Multi-channel NIR systems and LED arrays
  • Spectroscopic applications covering wide NIR ranges

This filter effectively isolates a broad NIR spectrum while blocking unwanted visible light and longer infrared wavelengths that could interfere with NIR detectors and sensors.

Ideal for researchers and engineers working with broadband NIR applications where comprehensive wavelength coverage is essential. Each filter is manufactured using advanced coating techniques and undergoes rigorous testing to ensure consistent optical performance across the entire passband.

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.
