Hollow Fiber Gas Cell
Gas cell blocks include an optical window, a fiber port, and a gas port. With two blocks you can convert a hollow fiber into a bench top gas cell for absorption spectroscopy or wavelength reference applications. Simply swap fibers for different path lengths.
Feature
Incredibly simple and robust alignment
Range of wavelengths: UV to LWIR
Range of pathlengths: 0.1to 5m
Low sample volume:< 10 mL
Compact size; flexible layout
Gas Cell OMEGA System
Standard Kit = 2 Gas Blocks + 1 Hollow Fiber
Non-optical parts | Stainless steel |
Fiber coating options | Aluminum (UV) Silver (VNIR) Silver-lodide (Mid-IR) |
Alignment
The relatively large fiber diameter (ID = 0.2 - 1.5 mm) and single pass configuration enables obtaining ‘first light” with minimal effort. In some cases, you can collimate your beam and mount your laser on one end and simply put your detector at the other end. It is that easy.
Versatile Systems
Gas cells kits can utilize a wide range of hollow core fiber optic waveguides. Options include different sample volumes, path lengths, and wavelength ranges.
