Products

Bristol Instruments offers a variety of optical interferometer-based products for scientists and engineers who are interested in Laser Spectral Characterization, WDM Wavelength Testing, or Non-Contact Thickness Measurement. Wavelength meters and spectrum analyzers are available to characterize CW and pulsed lasers that operate from the visible to the mid-IR. The wavelength of WDM lasers and WDM signals can be measured with a family of optical wavelength meters and multi-wavelength meters. And, an optical thickness gauge is offered to measure absolute thickness, a dimension that is critical in the development and production of materials such as specialty plastic films, medical tubing, and ophthalmic products.



WAVELENGTH METERS - SCIENTIFIC

Bristol Instruments’ wavelength meters are for scientists and engineers who need to know the exact wavelength of their lasers. These systems use proven interferometer-based technology to measure absolute wavelength to an accuracy as high as ± 0.0001 nm. To achieve the reliable accuracy that is expected from Bristol Instruments, all of its wavelength meters include a built-in wavelength standard for calibration. Systems are available for CW and pulsed lasers that operate at wavelengths from 375 nm to 12 µm.

  • 671 Series - CW lasers, 375 nm - 12 µm
  • 871 Series - Pulsed and CW lasers, 375 - 1700 nm, 1 kHz measurement rate

WAVELENGTH METERS - WDM

Bristol Instruments provides a family of optical wavelength meters and multi-wavelength meters designed specifically for the testing of WDM lasers and WDM systems. Absolute laser wavelength is measured to an accuracy as high as ± 0.3 pm. This performance is guaranteed by continuous calibration with a built-in wavelength standard and is traceable to NIST standards. Straightforward operation and rugged design satisfy the needs of both the R&D scientist and the manufacturing engineer.

  • 828B System - 1 kHz measurement rate, single wavelength, CW and modulated signals
  • 438 Series - 10 Hz measurement rate, multi-wavelength, CW and modulated signals
  • 428 Series - Multi-wavelength, CW and modulated signals
  • 228 Series - Single-wavelength, CW signals

SPECTRUM ANALYZERS

The spectrum analyzers from Bristol Instruments provide high-resolution spectral analysis and high-accuracy wavelength measurement in one instrument. These systems are for scientists and engineers who need to know the wavelength, bandwidth, and longitudinal mode structure of their lasers with the reliable accuracy that is required for the most demanding applications.

  • 771 Series - CW and high-repetition rate pulsed lasers, 375 nm – 12 μm

THICKNESS GAUGES

Bristol Instruments' optical thickness gauges are a simple and non-destructive way to precisely measure thickness of a variety of transparent and semi-transparent materials. Thickness information is critical in the development and production of materials such as contact and intraocular lenses, and medical products including balloon catheters, stents, bags, and tubing. Bristol combines high accuracy with straightforward operation and rugged design to make these instruments ideal for both laboratory and manufacturing environments.

  • 157 Series - Accuracy of ± 0.1 µm with repeatability of ± 0.02 µm
  • 137 Series - Accuracy of ± 1 µm with repeatability of ± 0.05 µm
