Method of making a corrosion resistant gas cell including an end cap having integral reflecting mirrors and sealing surfaces, the method involving the steps of: rough shaping a plate of stainless steel to near net dimensions using a standard-precision CNC milling machine and standard cutting bits to form a near net stainless steel core; coating the near net stainless steel core with a layer of nickel that is at least 0.002″ thick by immersing the near net stainless steel core in a bath of nickel sulfamate for at least eight hours; and precision shaping the coating of nickel with a precision milling machine to form the integral reflecting mirrors and sealing surfaces of the gas cell |
