Professional BP890-30 Near-Infrared Bandpass Filter - Precision NIR Filtering

Achieve superior near-infrared optical performance with our BP890-30 Bandpass Filter, precisely engineered for 890nm wavelength transmission. This premium optical component delivers exceptional filtering with a 30nm full-width half-maximum (FWHM) bandwidth, making it the perfect choice for NIR spectroscopy, machine vision, biomedical imaging, and advanced optical sensing applications.

Key Specifications:

  • Center Wavelength (CWL): 890nm - Optimal for near-infrared applications
  • Bandwidth (FWHM): 30nm - Excellent spectral selectivity and transmission
  • High NIR Transmission: Maximum light throughput in the near-infrared region
  • Sharp Spectral Cutoff: Superior out-of-band blocking performance
  • Professional Grade: Manufactured to stringent optical industry standards

Primary Applications:

  • Near-infrared spectroscopy and chemical analysis
  • Machine vision and industrial inspection systems
  • Biomedical imaging and tissue analysis
  • Laser diode filtering and beam conditioning
  • Agricultural and food quality assessment
  • Research and laboratory NIR applications
  • Optical communication systems

Technical Advantages:

Our BP890-30 filter utilizes advanced multi-layer thin-film coating technology optimized for near-infrared wavelengths. The 30nm bandwidth provides excellent signal isolation while maintaining high transmission efficiency, crucial for sensitive NIR measurements. Each filter undergoes rigorous spectral testing to ensure consistent performance across the entire aperture.

Near-Infrared Excellence:

The 890nm wavelength is particularly valuable for applications requiring deep tissue penetration, minimal water absorption, and reduced scattering. This filter's precise 30nm bandwidth ensures optimal performance in demanding NIR applications where spectral purity is critical.

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.

Standard Mountings
