Digital Lens Clock
Unlike our manual lens clock, the digital lens clock gives accurate readings for refractive index lenses (such as 1.49, 1.53, 1.56, 1.59, 1.61, 1.67, 1.71, 1.74). It can read out both negative and positive values. Also contains a memory function and auto power on/off.
With the purchase of a digital lens clock, you also receive a hard case that is lined with foam.
