What light path do I need to use to measure the absorbance of GOPOD Reagent while using β-Glucan Assay Kit (K-BGLU)?

The absorbance of 100 micrograms of glucose (0.1mL of standard at 1.0 mg/mL + 0.1 mL sodium acetate buffer) incubated with 3 mL of GOPOD Reagent measured at 510 nm and with a light-path of 1 cm should be approximately 1.0 absorbance unit.
