High Transmitting Bandpass Filters

We offer a high-transmittance variant of its standard bandpass filter selection. By tailoring the blocking range to match the detector, we can provide the maximum possible throughput while maintaining good blocking to meet the customer’s needs. Wavelengths include all popular laser, mercury biomedical, and analytical spectral lines. 

Description

High Transmitting Bandpass Filters

We offer a high-transmittance variant of its standard bandpass filter selection. By tailoring the blocking range to match the detector, we can provide the maximum possible throughput while maintaining good blocking to meet the customer’s needs. Wavelengths include all popular laser, mercury biomedical, and analytical spectral lines.

All filters are constructed using the same high-quality materials and methods as our standard bandpass filters, thus providing a highly stable, long-lasting filter.

These bandpass filters are designed for use in situations where far-infrared blocking is not required. They feature high transmission in the passband region and good blocking over a limited range. Theoretical transmission curves are available on request.

For even higher performance, please see our extensive selection of hard-coated bandpass filters.

BENEFITS

  • Wavelengths from the ultraviolet through the infrared
  • Stabilized to prevent drift of peak wavelength over time
  • Hermetically sealed and protected by an anodized aluminum ring
  • Transmission as high as 80%

COMMON APPLICATIONS

  • Spectral radiometry
  • Medical diagnostics
  • Chemical analysis
  • Colorimetry
