Orange-Red Fluorescence Bandpass Filter

The BP605-55 Bandpass Filter is precision-engineered for fluorescence microscopy and imaging applications in the orange-red spectral region. With its 605nm center wavelength and balanced 55nm FWHM, this filter delivers excellent performance for Rhodamine-based fluorophores and other orange-red emission applications requiring superior spectral selectivity.

Key Features:

  • Fluorescence Optimized: 605nm center wavelength ideal for orange-red fluorophores
  • Balanced Bandwidth: 55nm FWHM for optimal spectral performance
  • High Transmission: >88% peak transmission in passband
  • Superior Blocking: OD5+ blocking of unwanted wavelengths
  • Low Autofluorescence: Minimal background fluorescence for sensitive applications
  • Professional Grade: Hard-coated surfaces for demanding microscopy environments

Fluorescence Applications:

  • Rhodamine fluorophore emission filtering
  • Texas Red and Alexa Fluor 594 imaging
  • Multi-color fluorescence microscopy
  • Live cell imaging and time-lapse studies
  • Immunofluorescence and histology
  • Flow cytometry and cell sorting

Technical Specifications:

  • Center Wavelength (CWL): 605nm
  • Full Width Half Maximum (FWHM): 55nm
  • Passband Range: ~577.5nm to 632.5nm
  • Substrate: High-quality optical glass
  • Coating: Multi-layer fluorescence coating
  • Surface Quality: 40-20 scratch-dig
  • Parallelism: <30 arcseconds
  • Clear Aperture: >90% of diameter

Fluorescence Advantages:

The 55nm bandwidth provides optimal performance for:

  • Excellent collection efficiency for Rhodamine and similar fluorophores
  • Superior signal-to-noise ratio in fluorescence imaging
  • Compatibility with standard fluorescence filter sets
  • Minimal crosstalk with adjacent fluorescence channels
  • Optimal balance between signal collection and spectral selectivity

This spectral range (577.5-632.5nm) perfectly captures the emission characteristics of popular orange-red fluorophores while providing excellent blocking of excitation light and other unwanted wavelengths.

Perfect for researchers and microscopists working with fluorescence imaging, cell biology, and life science applications where precise orange-red emission filtering is critical for high-quality results. Each filter undergoes rigorous testing to ensure consistent performance and minimal autofluorescence background.

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.
