Improved Performance, Stability and FlexibilityIRVINE, Calif., Nov. 21 -- Newport Corp.'s new 910A series spatial filters use a novel optomechanical design that enables more rapid alignment and precise adjustment and delivers greater long-term stability than anything previously available. The modular 910A series offers a selection of nine different focusing objectives and 11 pinhole apertures, which can be easily changed for maximum operational flexibility. The optics are all antireflection coated for use over the 400-nm to 700-nm wavelength range.
The 910A series spatial filters are versatile laboratory tools ideal for use in any application that requires a visible laser beam free of spatial inhomogeneities. Typical uses include investigations in holography, interferometry, laser-based imaging and metrology in the semiconductor, communications, life science and research markets.
The 910A series features five-axis alignment -- xy translation of the pinhole, plus true gimbaling of the entire assembly. These adjustments are accomplished with high-resolution (100 threads/inch) screws, featuring large-diameter knobs for extremely sensitive and precise adjustment. Translation along the optical axis is also provided via a knurled ring that does not cause rotation of the pinhole, thus maximizing axial stability. Independent locks for each axis of translation and rotation securely hold the adjustment mechanism itself, not just the actuator screws, in order to maintain stable alignment. Moreover, engaging or disengaging each lock has negligible influence on position. These compact spatial filters are supplied with a removable slotted base plate for direct mounting to any surface with a ?-20 on 1 inch, or M6-1.0 on 25 mm, hole pattern. Alternately, they can be post-mounted using either a 8-32 or M4 threaded hole in the unit's lower surface.
