  • QA Optical Thickness Gage Smart Probe Datasheet

    Bristol Instruments’ Quick Align (QA) Optical Smart Probe is designed to offer unique alignment for use in production environments where the most precise and reliable information is required. A built-inn camera is included to detect the location of the reflected optical signal from the tested material. The alignment of the probe is then adjusted so that the optical signal is on target.

  • 871 Series Laser Wavelength Meter Brochure

    The 871 Series Laser Wavelength Meter from Bristol Instruments is designed to measure the absolute wavelength of pulsed and CW lasers. The wavelength meter provides the fastest measurement rates up to 1 kHz, which enables the wavelength characterization of individual laser pulses. Available for operation from 375 to 1700 nm, the 871 Laser Wavelength Meter utilizes a unique Fizeau etalon design that guarantees a measurement accuracy of ± 1 ppm (± 300 MHz at 1000 nm).

  • Advantages For Using 137/157 Optical Thickness Gauges

    The 137/157 Optical Thickness Gauges deliver reliably accuracy and exceptional repeatability for the most demanding thickness testing applications. These gauges are ideal for contact and intraocular lenses, medical balloon catheters, medical tubing, plastic films, laminates, glass, and adhesives.

  • Optical Thickness Gauge Probes Brochure

    Bristol Instruments offers a range of optical gauge probes for different thickness measurement applications. Probes are chosen based on the thickness of the material to be tested, the accuracy required while testing, and the need for simplified alignment.

  • Measuring Lens Assembly Thickness with the 157 Series Optical Thickness Gauge

    This technical note provides details on how the 157 Series Optical Thickness Gauge by Bristol Instruments can be used to determine the precise thickness of cemented or air-spaced achromatic doublets and triplets (as well as more complex lens stacks), and other lens assemblies.

  • Contact Lens Metrology with the 157 Series Optical Thickness Gauge

    Bristol Instruments’ 157 Series optical thickness gauge is ideal for contact lens metrology. Its guaranteed performance over long periods of time and its ability to measure absolute thickness to an accuracy of + 0.1 µm and repeatability as high as + 0.05 µm make it an ideal solution for this application.

  • Thermal Stability of the 157 Series Optical Thickness Gauge
