New!
The new Clarity Narrow Line Laser combines the absolute accuracy and traceability of our existing Clarity Precision Frequency Reference with new linewidth narrowing capabilities making it ideal for a wide range of interferometric applications. Linewidths < 30kHz available.
All of our Clarity products use Wavelength References gas cell technology to lock a diode laser source to a molecular absorption line offering superb long term stability.
See our datasheet or contact sales@wavelengthreferences.com for more information.
We offer traceable gas cells equivalent to the NIST SRM’s 2517 Acetylene Gas Cell, 2517A High Resolution Acetylene Gas Cell, 2519 Hydrogen Cyanide Gas cell, 2514 Carbon 12 Carbon monoxide Gas Cell, and 2515 Carbon 13 Carbon Monoxide Gas Cell. These devices are available in compact rugged aluminum housings with SMF28 fiber pigtails at a cost a fraction of the NIST devices and are fully traceable and functionally equivalent.
In addition to the standard gas cells we offer custom devices in a variety of materials and configurations. Our tri-gas cell has gas lines from 1510nm to 1640nm in one device. Our HF cell covers the 1300nm band. We can offer custom gas fillings either with pure gas or mixtures, some examples include methane, ammonia, hydrogen chloride, water, iodine, hydrogen sulphide, and others.
Wavelength References specializes in fiber coupled gas cells but also offers bare gas absorption tubes. These tubes are used where the device will be in a free space optical application or used at a wavelength where optical fiber is not applicable. We can fill a gas absorption tube with almost any gas or gas mixture.
