BRISTOL INSTRUMENTS, INC., located near Rochester, NY, was founded in January, 2005, by three technical and marketing leaders of the now-defunct Burleigh Instruments. Together, this group has over 70 years of combined experience in the design, manufacture, and marketing of lasers and precision test instruments used in basic and applied research, engineering, and production test applications.
The company currently focuses on the scientific, fiber communications, and optical metrology markets. The scientific market consists of researchers at universities, government laboratories, and industry who are involved in fields such as chemistry, physics, and optics. The fiber communications market consists of R&D and manufacturing engineers who need to accurately test DWDM components and transmission systems with respect to absolute wavelength. And, the optical metrology market consists of manufacturers that need to precisely measure critical physical dimensions of materials such as specialty plastic films, medical membranes, and ophthalmic products.
The primary technology utilized by Bristol Instruments is optical interferometry. Detailed analysis of interference phenomena, a consequence of the wave properties of light, can result in a variety of precise measurements. In particular, Michelson and Fizeau interferometer-based technologies are employed to develop instruments that provide reliable accuracy.
WDM WAVELENGTH TESTING
Bristol Instruments has developed a family of optical wavelength meters specifically designed for WDM testing applications. These instruments are ideal for the precise wavelength characterization of tunable WDM lasers, DFB lasers, and VCSELs. Bristol Instruments also offers multi-wavelength meters to fully characterize WDM transmission signals. With features such as straightforward operation and rugged design, these systems satisfy the needs of both the R&D scientist and the manufacturing engineer.
LASER SPECTRAL CHARACTERIZATION
WAVELENGTH METERS – SCIENTIFIC APPLICATIONS
Bristol Instruments’ wavelength meters provide accurate information for researchers who need to know the exact wavelength of their lasers. These systems use proven Michelson or Fizeau 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 wavelength meters use a built-in wavelength standard for automatic calibration. Systems are available for CW and pulsed lasers that operate at wavelengths from 350 nm to 12 µm.
SPECTRUM ANALYZERS – SCIENTIFIC APPLICATIONS
The spectrum analyzers from Bristol Instruments provide the most complete wavelength and spectral characterization of CW and high-repetition rate pulsed lasers that operate from 375 nm to 12 µm. These systems combine proven Michelson interferometer-based technology with fast Fourier transform analysis for accurate measurement of absolute wavelength to ± 0.0001 nm and high resolution spectral analysis to 2 GHz. As with all products from Bristol Instruments, every measurement is guaranteed by continuous calibration with a built-in wavelength standard.
NON-CONTACT THICKNESS MEASUREMENT
Bristol Instruments’ optical thickness gauge provides precise thickness information that is critical in the development and production of a variety of materials. These include ophthalmic products such as contact and intraocular lenses, medical products including balloon catheters, stents, bags, and tubing, as well as specialty plastic films, laminates, and flexible packaging.
