Wide-Bandwidth Green-Centered Visible Light Filter

The BP525-97 Bandpass Filter is engineered for applications requiring broad spectral coverage centered in the green region of the visible spectrum. With its 525nm center wavelength and wide 97nm FWHM, this filter provides extensive transmission spanning from cyan through yellow-orange wavelengths, making it ideal for broadband visible light applications.

Key Features:

  • Green-Centered Design: 525nm center wavelength optimized for visible light applications
  • Wide Bandwidth: 97nm FWHM for comprehensive spectral coverage
  • High Transmission: >85% average transmission across passband
  • Superior Blocking: Excellent rejection of UV, blue, and red wavelengths
  • Color-Balanced Performance: Natural color reproduction in green-yellow range
  • Durable Construction: Hard-coated surfaces for long-lasting performance

Versatile Applications:

  • Machine vision and industrial inspection
  • Fluorescence microscopy and imaging
  • Color measurement and analysis systems
  • Agricultural and vegetation monitoring
  • General illumination and lighting applications
  • Educational demonstrations and experiments

Technical Specifications:

  • Center Wavelength (CWL): 525nm
  • Full Width Half Maximum (FWHM): 97nm
  • Passband Range: ~476.5nm to 573.5nm
  • Substrate: High-quality optical glass
  • Coating: Broadband multi-layer coating
  • Surface Quality: 40-20 scratch-dig
  • Parallelism: <30 arcseconds
  • Clear Aperture: >90% of diameter

Wide Bandwidth Advantages:

The generous 97nm bandwidth makes this filter perfect for:

  • Applications requiring broad green-yellow spectral coverage
  • Machine vision systems with LED illumination
  • Fluorescence applications with multiple green fluorophores
  • Color-critical imaging where green sensitivity is important
  • Systems requiring tolerance to wavelength variations

This spectral range (476.5-573.5nm) covers the peak sensitivity region of the human eye and many CCD/CMOS sensors, making it particularly valuable for imaging applications where natural color perception and high sensitivity are important.

Perfect for researchers, engineers, and optical system designers working with machine vision, fluorescence imaging, and color analysis applications where broad green-centered spectral coverage provides optimal performance. Each filter is manufactured to exacting standards and tested for consistent 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.
