This objective has a working distance of 0.35 mm at a cover glass thickness of 0.3 mm silicon.

This objective for incident light brightfield features the M 27 threaded mount! This objective has been designed particularly for the infrared spectral range between 900 nm and 1,200 nm and for IR backside inspection, i.e. observation through the silicon wafer. It is mainly used at 1,064 nm (Nd-YAG-Laser) with the IR-LSM.
