Dark Current Test
Dark Current Test
The dark-current test measures the leakage current from each diode. The test is
used to check for leaking diodes which may cause non-linearity at specific
wavelengths. During the test, the slit assembly moves to the dark position,
cutting off all light falling onto the diode array. Next, the leakage current from
each diode is measured, and displayed graphically. The leakage current
(represented in counts) for each diode should fall within the limits.
