Manually Variable Optical Delay Line ODL-340 (:254KB)

Max. delay up to 330 psec

The ODL-340 uses an air-gap method to generate a delay in the optical signal. The duration of the delay is controlled by adjusting the position of a prism reflector so that the optical distance between the input and output collimators is varied. The device allows an adjustment of up to 49.5mm, corresponding to an optical delay of up to 330ps.
