Premium Deep UV Laser Line Bandpass Filter

The BP266-10 bandpass filter is engineered for the critical 266nm deep UV laser line, delivering exceptional performance for the most demanding ultraviolet applications. With its ultra-narrow 10nm full-width half-maximum (FWHM), this filter provides outstanding spectral selectivity and laser line cleanup in the challenging deep UV spectrum.

Exceptional Specifications:

  • Center Wavelength: 266nm ± 2nm precision
  • Ultra-Narrow Bandwidth: 10nm FWHM for maximum selectivity
  • High Deep UV Transmission: >80% peak transmission
  • Superior Blocking: OD3+ out-of-band rejection
  • Deep UV Resistant: Hard-coated for extreme UV durability

Critical Applications:

  • Nd:YAG fourth harmonic laser line cleanup
  • Deep UV laser spectroscopy and analysis
  • Semiconductor laser-based inspection systems
  • Advanced photolithography processes
  • Deep UV fluorescence microscopy
  • Precision laser micromachining

The 266nm Deep UV Laser Advantage:

At 266nm, this filter targets the fourth harmonic of Nd:YAG lasers, a critical wavelength for semiconductor inspection and advanced materials processing. The ultra-narrow 10nm bandwidth ensures exceptional laser line cleanup, removing unwanted spectral components that can compromise precision in deep UV applications.

Trust SyronOptics for your most demanding deep UV laser applications. Our specialized deep UV coatings and precision manufacturing ensure reliable performance in extreme ultraviolet environments where accuracy is paramount.

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.
