Page 13: Description
Description The SuperK VARIA is a plug & play filter accessory for the SuperK series of lasers. The VARIA provides a filtered output channel using a variable bandpass filter. The VARIA also includes a secondary output channel which emits the remaining portion of unfiltered light. -
Page 14: Top Panel
Features shutters are manually operated by turning the shutter knob between the Open and Closed positions as shown in Figure Figure 2 Auxiliary output – shutter knob set to open Output aperture shutters Open – emission unblocked Closed – emission blocked Caution: When the laser outputs are not in use, NKTP recommends to CLOSE the shutters. -
Page 15: Figure 3 Top Panel
Set the shutter to “Closed” to block emission and “Open” to unblock emission from the aperture. Mounting holes The two mounting holes (2) are designed to fasten the SuperK VARIA to either metric or imperial optical tables that have screw holes spaced at either 25 mm or 1” pitch. -
