The variable pathlength Venus cell described here is made of borosilicate glass. It has a pathlength that can be set anywhere from 1.6 meters to 6.4 meters. The volume is 0.75 liters.  This cell also comes in a variable pathlength mode with the micrometer adjustment to set the pathlength. The cell comes in nickel coated aluminum or stainless steel construction for more rugged applications.

This cell has larger mirrors over the 400 cc version. The larger mirrors collect a larger solid angle of radiation being reflected back and forth between the field mirror and the objective mirror. The basepath is slightly longer giving a longer pathlength for any fixed number of reflections. The performance is excellent. The ratio of pathlength to volume is highest for this family of gas cells giving it excellent energy throughput and IR performance.

The base price for a borosilicate cell body gas cell starts at $5,400.00. The price for Ni coated Al cell and 316 stainless gas cells are higher. The price is even higher depending on o-rings and windows. We can interface one our gas cells to any FTIR spectrometer brand.
