Acetylene Fiber-Coupled Gas Cell, 3 cm Path Length, SC/PC

• Hydrogen Cyanide and Acetylene Gasses Available for Wavelength Coverage of 1510 to 1565nm
• FC and SC Fiber Connection Options with a Variety of Path Lengths Available
• NIST Traceable Reference Cells

Wavelength References Fiber-Coupled Gas Cells are FC/APC, SC/APC, FC/PC, or SC/PC connected fiber coupled, gas filled precision filters whose absorption wavelengths depend on specific molecular energy level transitions that may be used as wavelength standards. Hermetically sealed to maintain  >10 year lifetime, these gas cells feature metal housings, wedged windows, and coated optics for minimum interference artifacts and can be easily integrated into existing benchtop systems. Wavelength References Fiber-Coupled Reference Cells are available with a variety of path lengths and pressures which meet the requirements of NIST Standard Reference Material® (SRMs) 2517a, 2519, or 2519a.  Short path lengths are recommended for measuring gasses at high concentration while longer path lengths enable more sensitive measurements. These reference cells are ideal for spectroscopy, wavelength/frequency locking, laser calibration, and optical gas sensing systems.  Hydrogen Cyanide (H¹³C¹⁴N) has been identified by national standards bodies as the primary wavelength reference in the C-band (1530 – 1565nm) while Acetylene (¹²C₂H₂) is recognized as a primary wavelength reference in the 1510 to 1540nm band.
