Broad-Band High-Throughput Filter - BP450-90

Maximize light collection efficiency with our BP450-90 bandpass filter, designed for applications requiring broad spectral coverage at 450nm wavelength with exceptional light throughput.

Key Specifications:

  • Center Wavelength (CWL): 450nm - Blue wavelength transmission
  • Full Width Half Maximum (FWHM): 90nm - Broad bandwidth for maximum light collection
  • High Transmission Efficiency: Optimized coating for superior light throughput
  • Smooth Passband: Consistent transmission across the entire bandwidth
  • Reliable Performance: Stable characteristics across operating conditions
  • Cost-Effective Solution: Excellent performance-to-price ratio

High-Throughput Applications:

  • Machine vision systems - Ideal for broad-spectrum blue light detection and analysis
  • General fluorescence microscopy with broad-spectrum blue fluorophores
  • Industrial inspection and quality control
  • LED and light source characterization
  • Color sorting and optical classification systems
  • Educational and training laboratory use
  • General spectroscopy and optical analysis
  • Biomedical imaging with high sensitivity requirements

Performance Benefits:

The broad 90nm bandwidth provides maximum light collection while still offering useful spectral filtering. This makes it perfect for applications where signal strength is the primary concern and broad spectral acceptance is beneficial.

Application Advantages:

Ideal for light-starved applications where you need to collect as much signal as possible. The broad bandwidth ensures excellent signal-to-noise ratios in the most challenging lighting conditions while still providing some degree of spectral discrimination.

Why Choose SyronOptics BP450-90?

Our broad-band filters deliver maximum light efficiency with consistent quality manufacturing. Each filter is designed to provide the highest possible light throughput while maintaining the optical quality standards expected from professional components.

High-efficiency optical component trusted by engineers and system integrators for applications requiring maximum light collection with basic spectral filtering capabilities.

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
