Variable Beam Splitters on Customer Request

Variable beam splitters have a inhomogeneous layer distribution on a square substrate.

The components are used to incorporate two beams in an assembly with a

single laser when the laser power of both partial beams were supposed to be
identical following the last optic in the system. This is impossible with
conventional beam splitters because the different components transmit light

The beam splitters are based on a customer request. The designs depend on
the wavelength: If a variable beam splitter is developed for a wavelength of 532
nm, it does not function at another wavelength. For example, for 1064 nm
designs, transmissions from 45% to 55% and 10% to 70% are available, or for
the wavelength 753 nm transmissions from 4% to 20%.

Two standard sizes are offered: 45 mm x 22 mm and 70 mm x 22 mm. Other sizes
are available but the maximum length of the substrates is restricted at 70

SCHUNK's New Safety Gripping System EGN

With the SLS, SOS, and STO functionalities, the SCHUNK EGN gripping system certified in accordance with DIN EN ISO 13849 enables safe human/machine collaboration. If the production process is interrupted by an emergency shut-off, the SCHUNK EGN goes into either a safely limited speed mode or a safe stop mode depending on the activated protection zone. In contrast to other solutions available on the market, the SCHUNK safety gripping system is continuously powered even in the safe operating stop so that the gripped parts are reliably held even without mechanical maintenance of gripping force. As soon as the protection zone is released, the gripper immediately switches back to the regular operating mode without the system having to be restarted.
