Wide-Bandwidth UV-A Bandpass Filter

The BP360-90 Bandpass Filter is engineered for ultraviolet applications requiring broad spectral coverage in the UV-A region. With its 360nm center wavelength and wide 90nm FWHM, this filter provides extensive UV transmission spanning from the UV-B boundary well into the visible spectrum, making it ideal for broadband UV applications and fluorescence excitation.

Key Features:

  • UV-A Optimized: 360nm center wavelength for comprehensive UV-A coverage
  • Wide Bandwidth: 90nm FWHM for extensive spectral range
  • High UV Transmission: >80% average transmission across passband
  • Superior Blocking: Excellent rejection of visible and IR radiation
  • UV-Resistant Design: Specialized coatings for long-term UV exposure
  • Low Autofluorescence: Minimal background fluorescence for sensitive applications

Versatile Applications:

  • Broadband fluorescence microscopy and imaging
  • Multi-fluorophore excitation systems
  • UV spectroscopy and analysis
  • Industrial UV inspection and quality control
  • Photochemistry and photobiology research
  • Environmental monitoring and sensing

Technical Specifications:

  • Center Wavelength (CWL): 360nm
  • Full Width Half Maximum (FWHM): 90nm
  • Passband Range: ~315nm to 405nm
  • Substrate: UV-grade fused silica
  • Coating: Broadband UV-optimized dielectric layers
  • Surface Quality: 40-20 scratch-dig
  • Parallelism: <30 arcseconds
  • Clear Aperture: >90% of diameter

Wide Bandwidth Advantages:

The generous 90nm bandwidth makes this filter perfect for:

  • Applications requiring broad UV-A spectral coverage
  • Multi-fluorophore systems without filter switching
  • Broadband UV sources and LED arrays
  • Systems requiring tolerance to UV wavelength variations
  • Maximum light gathering efficiency in UV applications

This spectral range (315-405nm) spans the entire UV-A region and extends slightly into the visible violet, making it particularly valuable for fluorescence applications where multiple UV fluorophores need to be excited simultaneously.

Perfect for researchers and engineers working with broadband UV applications, multi-fluorophore imaging, and UV spectroscopy where comprehensive UV-A coverage eliminates the need for multiple filters or complex filter switching systems. Each filter undergoes rigorous UV exposure testing to ensure long-term stability and performance.

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.
