Automatic calibration with a built-in wavelength standard guarantees this performance to ensure the most meaningful experimental results.<\/p>\n<p><strong>Fastest sustained measurement rate<\/strong><br \/>\nThe 871 Laser Wavelength Meter generates a spatial interferogram that is detected by a fast photodetector array. An on-board digital signal processor quickly converts the interferometric information to wavelength. Because this calculation is done internally, a sustained measurement rate as high as 1 kHz is achieved.<\/p>\n<p>Wavelength measurements can be reported at this rate by data streaming with an RS-422 serial interface, or an internal data buffer is available to save up to one million measurements.<\/p>\n<p><strong>Convenient laser input and straightforward operation<\/strong><br \/>\nA laser under test enters the 871 Laser Wavelength Meter through a pre-aligned fibre optic input connector. This ensures optimum alignment of the laser beam to the system\u2019s Fizeau etalons resulting in uncompromised accuracy.<\/p>\n<p>The 871 Laser Wavelength Meter operates with a PC connected directly by USB or though a local area network via Ethernet. Software is provided to control measurement parameters and to report wavelength data, or the system can be integrated directly into an experiment using a library of commands for custom or LabVIEW programming. In addition, a browser-based application can be used with a tablet or smartphone to display laser wavelength information anywhere in the laboratory.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The 871 Laser Wavelength Meter uses a proven Fizeau etalon design to measure the wavelength of pulsed and CW lasers to an accuracy as high as \u00b1 0.2 parts per million (\u00b1 0.0002 nm at 1000 nm).<\/p>\n","protected":false},"featured_media":49996,"template":"","meta":{"_acf_changed":false,"footnotes":""},"product_brand":[],"product_cat":[217],"product_tag":[],"class_list":{"0":"post-49901","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-pulsed-cw-wavelength-meters","8":"first","9":"instock","10":"shipping-taxable","11":"product-type-simple"},"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.6 (Yoast SEO v27.7) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>871 Series Pulsed &amp; CW Laser Wavelength Meter - 871 Series Laser 2000<\/title>\n<meta name=\"description\" content=\"871 Series pulsed &amp; CW laser wavelength meter.
