Description
The BBP-560 is a narrowly tuned bandpass filter with an approximately 49 nm bandwidth, centered at 553 nm and passing light from 535 nm to 584 nm (50 % points). Peak transmission is 97.3 % at the center wavelength. The filter achieves deep blocking outside the pass-band: red transmission drops to 1 %, blue to 0.1 %, and NIR is suppressed below 0.1 %. Green transmission within the pass-band is moderate (36.4 %) due to the narrow bandwidth, while yellow is partial (55 %). The distinctive characteristic is a transparency window in the SWIR(1000-1200) band at 39.2 %, making BBP-560 suitable for applications requiring both visible green isolation and SWIR sensing.
Key Advantages
- Tight green isolation - The narrow 535-584 nm pass-band with 97.3 % peak transmission isolates green wavelengths with minimal bleed-through to red (1 %) or blue (0.1 %), ideal for monochromatic green imaging.
- Deep red and blue rejection - Red transmission (1 %) and blue (0.1 %) are suppressed to near-background levels, eliminating color cross-talk and enabling pure green-channel analysis from broadband light sources.
- Hard-oxide ion-assisted coating - Durable narrow-bandpass coating maintains spectral performance and peak transmission through thermal stress, mechanical handling, and long-term laboratory use.
- SWIR transparency window - The 39.2 % SWIR(1000-1200) transmission creates a dual-band filter capable of simultaneous visible green and short-wave-infrared sensing in a single optical element.
- Full customization options - Round, square, and free-form blanks from 5 mm to 450 mm diameter, thickness 0.21-3.8 mm, on Borofloat, soda-lime, Schott D263 T, or Corning Eagle XG substrates.
Typical Applications
- Green laser selection and isolation - The 535-584 nm pass-band efficiently selects green laser wavelengths (532 nm, 555 nm, 561 nm) while rejecting red and blue lines for clean green-only applications.
- Chlorophyll and plant imaging - Green light penetrates plant tissue and chlorophyll exhibits complex absorption in the 535-584 nm band, making this filter ideal for plant phenotyping and agricultural diagnostics.
- Dual green-SWIR sensing - The combination of narrow green pass-band and 39 % SWIR transmission enables simultaneous visible chlorophyll imaging and thermal/SWIR material analysis in single-sensor applications.
- Fluorescence microscopy - Isolates green fluorophore emission (GFP, FITC, Alexa 488) with high specificity while the SWIR window enables simultaneous NIR fluorophore detection or thermal background measurement.
- Environmental and water monitoring - Green light has optimal water penetration; the narrow 535-584 nm band supports underwater imaging and water-quality analysis while SWIR capability enables thermal or material sensing.
