Ultra-Wide Bandwidth Visible Light Filter

The BP650-300 Bandpass Filter is designed for applications requiring exceptionally broad spectral coverage in the visible spectrum. With its 650nm center wavelength and ultra-wide 300nm FWHM, this filter provides comprehensive visible light transmission while blocking unwanted UV and near-infrared radiation.

Key Features:

  • Visible Light Optimized: 650nm center wavelength for optimal visible spectrum coverage
  • Ultra-Wide Bandwidth: 300nm FWHM spanning most of the visible spectrum
  • Broad Transmission: >80% average transmission across passband
  • UV/IR Blocking: Effective blocking of ultraviolet and near-infrared radiation
  • Color-Neutral Design: Minimal color distortion across visible spectrum
  • Durable Construction: Hard-coated surfaces for long-lasting performance

Ideal Applications:

  • White light imaging and photography
  • Color measurement and analysis systems
  • General illumination and lighting applications
  • Machine vision and inspection systems
  • Educational demonstrations and experiments
  • Broadband visible spectroscopy

Technical Specifications:

  • Center Wavelength (CWL): 650nm
  • Full Width Half Maximum (FWHM): 300nm
  • Passband Range: ~500nm to 800nm (covers most visible spectrum)
  • Substrate: High-quality optical glass
  • Coating: Multi-layer broadband coating
  • Surface Quality: 40-20 scratch-dig
  • Parallelism: <30 arcseconds
  • Clear Aperture: >90% of diameter

Ultra-Wide Bandwidth Advantages:

This exceptional 300nm bandwidth makes the filter perfect for:

  • Applications requiring natural color reproduction
  • Systems working with broadband white light sources
  • Blocking unwanted UV and IR while preserving visible light
  • General-purpose visible light filtering without spectral bias

The filter effectively acts as a visible light isolator, removing harmful UV radiation and unwanted infrared while maintaining excellent transmission across the entire visible spectrum from blue to red.

Ideal for applications where you need to work with the full visible spectrum while eliminating out-of-band radiation that could interfere with sensors, cameras, or optical systems.

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.
